   You could  enter up to 6 different roof types onto the Master Roof, Wall,
and Partition  Data screen.   Each roof type has a reference number, and the
reference number  of one  of the defined roofs should be entered here.  Note
that if  the zone  has a  conditioned floor  or a return-air plenum above it
then you  do not  need to  enter a  roof for it.  If the roof is 100% glass,
then it  should be  entered as  glass with  a tilt  of 180  and 0 reference.

   This entry  can be used to define exterior walls and partitions.  Input a
"P" in  the DIR/TYPE field to specify a partition.  To specify a wall, input
the wall orientation.                                                       
                                                                            
   You could  enter up to 8 different wall types onto the Master Roof, Wall,
and Partition  Data screen.   Each wall type has a reference number, and the
reference number  of one  of the  defined walls may be entered here.  If the
wall is  100% glass then it should be entered as a glass with a reference to
a wall.   It  is sufficient  to enter  only the direction of that wall.  The
following wall types are currently defined.

   Walls or  floors that  are more than 5 feet below grade should be entered
as partitions.   Partitions  can also  be used  to account  for "extra" heat
losses or  gains that affect the zone.  Of course, a partition should always
be specified when a zone adjoins an unconditioned zone.  You can enter up to
8 different  partition types  onto the Master Roof, Wall, and Partition Data
screen.   Each partition  type has  a reference  number, and  the  reference
number of  one of the defined partitions may be entered here.  The following
partition types are currently defined.

   Use this  entry for windows, horizontal skylights, glass walls, and glass
doors.   You can  enter up to 20 different glass types onto the Master Glass
Data screen.   Each  glass type  has a  reference number,  and the reference
number of  one of  the defined  glass types  should be entered here.  If the
roof is  100% glass, then it should be defined as a glass with a tilt of 180
degrees and  0 reference.  If the  wall is  100% glass,  then it  should  be
defined as  a glass  with a  reference to a wall. It is sufficient to define
only a  direction for  this wall.   The  following glass types are currently

                         Exit to Operating System                           
   Selection "0"  of the  Master Menu is used to exit CHVAC.  Always be sure
to exit  CHVAC with  this selection  or the  ESCAPE key  so that all of your
input data  can be stored properly.  Exiting by turning off the computer can
cause loss of input data.                                            ESD 149
                      Enter/Edit General Project Data                       
   Selection "1"  of the  Master Menu  is used  to enter  and  edit  general
project data  such as  client information  and building  opening and closing
hour.   Some of  the General  Project data applies to the project as a whole
and can  be modified  for individual  zones.   This so-called "default" data
includes: lighting and equipment loads per square foot, number of people per
square foot,  load per  person, safety  factors,  and  type  of  calculation
specification.  This selection is also used to define the people, equipment,
and lighting load profiles.                                          ESD 154
                Enter/Edit Outdoor/Indoor Design Conditions                 
   Selection "2"  of the  Master  Menu  is  used  to  enter  and  edit  data
concerning the  degrees latitude, altitude, and design temperatures.  You do
not have  to know  any climate  information for your project if it is one of
the over 300 cities that are included in CHVAC's built in weather data base.
To see if your city is part of CHVAC's data base, simply type the first five
letters of your city into the CITY REFERENCE input.  If your city is part of
the data base, suggested values will be filled in for you.           ESD 163
                   Enter/Edit Master Roof and Wall Data                     
   Selection "3"  of the  Master Menu  is used  to define  the 5 Master Roof
types, 5  Master Partition  types, and 6 Master Wall types allowed by CHVAC.
The ASHRAE  code, U-factor, and color are entered here, and only a number is
entered to indicate the appropriate roof, wall, or partition on the Detailed
Zone screen.                                                         ESD 171
                       Enter/Edit Master Glass Data                         
   Selection "4"  of the  Master Menu  is used to define the 20 Master Glass
types allowed  by CHVAC.   The  winter and summer U-factors, shading coeffi-
cients, room  construction, and glass dimensions are entered here.  Then the
glass types are referred to by number in the Zone Data screen.       ESD 177
                     Enter/Edit Exterior Shading Data                       
   Selection "5"  of the  Master Menu is used to enter the dimensions of any
overhangs or  fins you  might have on the building.  Note that if you do not
have any external shading you can leave this screen blank.           ESD 182
                    Enter-Edit Air Handler System Data                      
   Selection "6" of the Master Menu is used to enter and edit data about the
air handling  systems in the building.  Note that while you can define up to
999 different  air handlers,  the zones  can only  use one air handler each.
Some of  the input  items on  this screen  include: air handler description,
terminal type,  fan type,  duct losses,  and outside  air information.  This
screen is  also used  to describe  pretreated air (if any) and allows you to
change the indoor design conditions for each air handler.            ESD 186
                       Enter/Edit Detailed Zone Data                        
   Selection "7"  of the Master Menu is used to enter and edit zone specific
data such  as the height and length of walls, the number of people, lighting
and equipment  watts, and  the air  handler number.   At  the bottom  of the
screen is  a option to edit the Miscellaneous zone data, delete the zone, or
rotate the  zones.   Miscellaneous data is: the type of calculation (heating
or cooling),  safety factors,  internal load  profiles,  loads  per  person,
latent equipment  load, ceiling height, and outside air CFMs.  The Miscella-
neous Data  screen is  also used  to quickly  inactivate a  zone,  duplicate
zones, specify  the perimeter  of a  floor slab,  or specify  the area  of a
zone's ceiling affected by a return-air plenum.                      ESD 194
                          Enter/Edit Plenum Data                            
   Selection "8"  of the  Master Menu  is used  to specify that the "plenum"
space (the  area between the roof of the building and the suspended ceiling)
is being  used to  direct return  air back  to the  air handling  unit.  The
plenum space  requires such  zone specific  data as the height and length of
walls and  the equipment  watts.   Other information  such as the percent of
lighting load to the plenum and the U-Factor of the plenum floor is required
as well.                                                             ESD 205
                         Rotate Zone Orientations                           
   Selection "9"  of the  Master Menu  is used to "rotate" the zones so that
the orientations  for all  of the  walls and  glass sections  can be changed
automatically to  the desired  orientation.   Note that  you can also rotate
zones from the Zone Data screen.                                     ESD 213
                       Compute and Print HVAC Loads                         
   Selection "C"  of the  Master Menu is used to print the reports either to
the printer  or to  the monitor.   There  are nine different reports you can
specify and  they cover  different aspects  of input  and output  data.  The
hour-by-hour load  profile, supply CFM required by each zone, and return and
supply side  loads are  part of  the Air System Summary report, and the skin
loads, other  building loads, and check figures are included in the Building
Load Summary  report.   You can also set the left margin, the beginning page
number, and the number of zones to print.                            ESD 218
                          Enter/Edit Weather File                           
   Master Menu selection "W" should be rarely used.  It has been included to
allow you  to add  climate data  for your own location if you want.  You can
also change  the weather  data for  a given  city or  change the  name of an
existing city.   This  selection should  not be  used casually  because  any
changes made to the existing data base are permanent.  Once you have changed
a value,  the original value cannot be recovered.  Use Master Menu selection
"2" to make changes that apply to this project only.                 ESD 227
            File Operations:  Delete-Copy-Rename Project Files              
   Master Menu  selection "F"  is a utility selection that can be used for a
variety of  operations including:  backing up  the project  data files  to a
floppy when  running from  a hard  drive, copying  project data files from a
floppy to  the hard  drive, creating a duplicate copy of an existing project
(with a  different name), changing the name of an existing project data file
(to correct a misspelling, for example), and deleting project data files you
don't want any more.                                                 ESD 235
                            Restart New Project                             
   Selection "R"  of the  Master Menu is used to tell CHVAC that you wish to
start another  project.  After using this selection all current data will be
saved and you will be allowed to enter a new project data file name. ESD 243
                      General Project and Client Data                       
   Four input  fields are  provided that  allow  you  to  enter  descriptive
information for  such items  as  the  project  name,  client  name,  project
location, and  designer.   These  inputs  can  contain  any  combination  of
characters and numbers, but the length of the descriptions cannot exceed the
field widths indicated.                                              ESD 247
                     Building Opening and Closing Hour                      
   The Building  Opening Hour  is the  solar hour  (1-24) at which HVAC load
calculations should  be started,  and the Building Closing Hour is the solar
hour (1-24)  at  which  HVAC  load  calculations  should  be  halted.    "1"
corresponds to  1 A.M  and "24"  corresponds to  12 Midnight.  Note that the
building opening  hour must be numerically smaller than the building closing
hour.                                                                ESD 253
              Watts of Lighting and Equipment Per Square Foot               
   This input  allows you  to specify the watts that you wish to be added to
each zone  on a  per square  foot basis.   Lighting is typically 2 watts per
square foot  while equipment is typically 1 watt per square foot.  Note that
it is also possible to directly input the watts of lighting or equipment for
any zone and thus void the effect of this input.                     ESD 260
                     Number of Square Feet Per Person                       
   This input  allows you  to indirectly specify the number of people in the
zones by  specifying the  number of  square feet per person.  General office
space typically  uses 100  square feet  per person.   Note  that it  is also
possible to  directly input the number of people occupying any zone and thus
void the  effect of  this input.  See the appendix of your User's Manual for
more suggested values.                                               ESD 266
                          People Diversity Factor                           
   The people  diversity factor  is shown in Table 1.1, page 1.3 of ASHRAE's
GRP 158.   This  factor is  used to  account for people moving around in the
building.   Although the maximum number of people should be entered for each
zone to  insure enough supply air, this number should be reduced somewhat at
the building  level to  avoid oversizing.   The  people diversity  factor is
normally 100  percent (100)  except in  certain situations.   Buildings with
auditoriums typically need people diversity factors.                 ESD 273
                    Sensible and Latent Heat per Person                     
   This value  accounts for  sensible (dry  bulb) and latent (wet bulb) heat
contributed by  people to  the zones.   A  default value is entered into the
General Project  Data screen,  which can be modified on a zone by zone basis
with the  Miscellaneous data  option.   If a  zero is entered for the people
multipliers in  the Miscellaneous  Data screen,  the value  entered into the
General Project data screen will be used for that zone.  The heat per person
is multiplied by the number of people in each zone to determine the sensible
and latent load due to people.  The following table reproduced from the 1989
ASHRAE Handbook  of Fundamentals  offers suggested  sensible and latent heat
gain values for a mixed group of occupants for various activities.

    Sensible, Latent, and Heating Safety Factors - General Project Data     
   These inputs  allow you  to specify  the percentage  of  the  HVAC  loads
(whether its sensible gain, latent gain, or winter heating loss) that should
be added  as a  safety factor.   These  factors  are  used  to  artificially
increase the  actual loads  computed.   Enter a  number from  0  (no  safety
factor) to 50 (a 50% safety factor).  Note that °10ð% is common.     ESD 310
          Floor Heat Loss Coefficient for Exposed Slab Perimeters           
   If the  edge of  the ground  floor slab is exposed (e.g. concrete slab on
grade), you  should enter  a heat  loss coefficient appropriate for the slab
and wall  construction.  The perimeter of the floor must be entered into the
Miscellaneous Zone  Data screen  for the  appropriate zone.   Note that this
heat loss coefficient is per degree Fahrenheit and will be multiplied by the
winter temperature difference and the perimeter in linear feet.  Some common
coefficients for concrete slab on grade floors are shown below.

                      Building Default Ceiling Height                       
   This input allows you to input the average height of the ceiling in feet.
Note that  this is  a default  entry in  that it applies to all zones in the
project unless  specifically overridden  for a  given zone  in the Miscella-
neous Data screen for that zone.                                     ESD 338
                       Building Default Wall Height                         
   This allows  you to  input the  average wall  height for  the building in
feet, which  acts as a default value for the building.  Each time a new zone
is created,  this value  is copied  into all the wall heights for that zone.
The wall height can also be modified at the individual zone level.          
                                                                            
   If this  default value is later modified, the program gives you an option
to apply  this modification  to all  defined walls, with the default height.
It is  important to  note that the program modifies only the default values.
Any other value input by you individually will not be modified.      ESD 343
   Enter 1 For Just Cooling Load Calculations, 2 For Heating, 3 For Both    
   This input  allows you  to specify  what calculations should be performed
for the  project.   Note that  this is a default entry in that it applies to
all zones  in the project unless specifically overridden for a given zone in
the Miscellaneous Data screen for that zone.                         ESD 353
                          Reference Number - Hour                           
   Enter a number from 0 to 100 representing the percentage of the load that
is felt at the given hour.  Each of these profiles could be either a people,
lighting, or equipment load profile, depending on how it is selected for the
air handler.   The  load profiles can also be altered for each zone with the
Miscellaneous Zone  data screen.   Note  that the People Diversity Factor is
different from  the People  Load Profile.   The  diversity factor is used to
adjust the  number of  people at  the building  level and is not felt at the
zone or air handler level.                                           ESD 358

   Note that  if you  entered a  city and state that are part of the weather
data base,  a suggested  altitude will  be filled  in for you.  The altitude
(feet above sea level) allows CHVAC to predict the density of the air at the
project location.   Accurately  entering the  altitude will  allow CHVAC  to
automatically adjust computed air quantities for density considerations.  If
you want  CHVAC's results  to agree  with standard  "psych" charts which are
usually computed for zero feet above sea level, then you should enter a zero
into this input item.                                                ESD 367
                             Degrees Latitude                               
   Note that  if you  entered a  city and state that are part of the weather
data base,  the degrees  latitude will  be filled  in for  you.  The degrees
latitude is  used to  obtain the appropriate maximum solar heat gain factors
for glass  solar loads  and should be entered as nearly as possible.  If you
live south  of the  equator be  sure to  enter your  latitude as  a NEGATIVE
number.   If the latitude is one of the four degree increments (0-64) of the
ASHRAE Handbook  of Fundamentals, the exact solar heat gain factors from the
tables will  be used.   Otherwise, CHVAC will interpolate between the tables
to obtain the appropriate solar heat gain factors.                   ESD 376
                       Mean Daily Temperature Range                         
   The mean  daily temperature  range is  the average difference between the
daily high  and daily  low temperatures  for a given location in the summer.
Note that  if you entered a city and state that are part of the weather data
base, a  suggested daily  temperature range will be filled in for you.  High
temperature ranges  (typically occurring in dry locations) decrease the load
on the HVAC cooling system.  Valid values of MDTR range from 5 to 80 degrees
while 20 is common.                                                  ESD 386
                        Winter Outdoor Temperature                          
   Enter the  coldest temperature  in degrees  Fahrenheit that you expect to
occur in the winter.  The winter design temperature is used to determine the
worst case heating load and you can change this value at any time.   ESD 394
                         Winter Indoor Temperature                          
   Enter the  indoor temperature (Deg F) that you want the heating system to
maintain during the coldest winter months.                           ESD 398
                           Cooling Design Month                             
   Note that  if you  entered a  city and state that are part of the weather
data base,  at least  one suggested  design month  will be  shown (and  most
cities have  all six  design months  filled in).   Design months are used to
determine the  peak cooling  load on  a zone.   CHVAC  can calculate cooling
loads for  any of  the 12  months and  you can  specify up  to six different
months with  this entry.  Enter the number (from 1 to 12) of the month(s) in
which you  want cooling  load calculations  performed.  A "1" corresponds to
January and  a "12"  corresponds to December.  Normally, you will enter only
summer months  into this  field.   The only  reason you would enter a winter
month in  this field would be if you have a lot of south facing glass in the
building.  Solar loads are quite high for south facing glass in December and
January (north  latitudes) and  you could conceivably have a maximum cooling
load in December or January for a particular zone.                   ESD 401
             Cooling Outdoor Dry Bulb and Wet Bulb Temperature              
   Enter the  highest dry  bulb and the mean coincident wet bulb temperature
(Deg F) expected during the design month specified.                  ESD 415
                   Indoor Dry Bulb and Relative Humidity                    
   Enter the  indoor dry  bulb temperature (Deg F) and the relative humidity
in percent  (Ex. 50  for 50%)  that you  wish to  maintain in  the zone  for
cooling purposes during the specified design month.                  ESD 418
                            ASHRAE Roof Number                              
   In accordance  with ASHRAE  procedures you  must select  an  ASHRAE  roof
number (1-13)  that is  most like  this roof  type.   Below is a list of the
ASHRAE roof  numbers complete  with description, weight per square foot, and
sample U-factors.   The ASHRAE roof number refers to the ability of the roof
to store  and radiate  heat ONLY.   Roof  number 1  radiates its heat almost
immediately while  roof number  13 stores  its heat for several hours before
radiating it into the zone.  So if in doubt, try to match the heat radiating
characteristics of the roof rather than the material type or U-factor.

                    Roof, Wall, and Partition U-Factor                      
   This input allows you to enter the actual U-Factor (overall heat transfer
coefficient) of your roof, wall, or partition section.  Remember that the U-
Factor is  computed by  taking  the  reciprocal  of  the  sum  of  the  heat
resistance values  (so called R-Values) of each component in the roof, wall,
or partition  under consideration.   See  the ASHRAE Handbook for details on
this procedure.                                                      ESD 457

or enter  2 if the inside surface of the roof section is the ceiling such as
with vaulted roofs commonly found in churches.                       ESD 467
                   Cooling Temperature Difference (CTD)                     
   This input  requires you to enter the temperature difference in degrees F
across the  partition for  the case  where the  unconditioned  side  of  the
partition is at its hottest.  Typically, an unconditioned space will be 3 to
10 degrees hotter than the zone.                                     ESD 471
                   Heating Temperature Difference (HTD)                     
   This input  requires you to enter the temperature difference in degrees F
across the  partition for  the case  where the  unconditioned  side  of  the
partition is  at its  coldest.  Typically, an unheated space will be from 10
to 20 degrees colder than the zone.                                  ESD 476
                       ASHRAE Wall Group Code (GRP)                         
   In accordance with ASHRAE procedures you must select an ASHRAE wall group
code (A-G)  that is most like the actual exterior wall being defined.  Below
is a  list of  the ASHRAE  wall types  complete with description, weight per
square foot,  and U-factor.   Your  selection should  be based mostly on the
similarities of  the ASHRAE wall construction and mass description with your
wall.   Do not  worry about closely matching U-factors.  Note that the walls
become less massive with each increment in wall type.

                   Glass Shading Coefficient (SHD.COEFF)                    
   Glass shading  coefficients should  ideally be obtained from the manufac-
turer of  the specific  glass to  be used  in the  building.   However, some
shading coefficients for some common glass types are shown below.  Note that
this shading  coefficient is  used if  the glass  does not have any interior
shading.   When the  glass does  have interior shading, the Internal Shading
Coefficient is used.

   This input  requires that you enter "1" if internal glass shading devices
such as  drapes, blinds, or shades are being used.  Enter "2", "3" or "4" if
they are not present or if they will be open during occupied daylight hours.
If you  enter a  "1", the  Internal Shading  Coefficient will be used in the
calculations.   Otherwise, the Glass Shading Coefficient will be used in the
calculations.                                                               
                                                                            
   Input values  of "2",  "3" and  "4" allow  the program  to use  different
Cooling Load  Factor tables for glass without interior shading from the 1989
ASHRAE Handbook of Fundamentals.  These tables are referred to as "General",
"Carpeted" and "Uncarpeted", respectively.                           ESD 634
                       Internal Shading Coefficient                         
   Glass shading  coefficients should  ideally be obtained from the manufac-
turer of  the specific  glass to  be used  in the  building.   However, some
shading coefficients for some common glass types are shown below.  Note that
this shading  coefficient is  used when the glass has interior shading (such
as drapes,  blinds, roller  shades that  are closed  during the  day in  the
summer).  If the glass is NOT shaded, you can leave this value blank.

   Enter the  width and  height of  the glass section in decimal feet.  Note
that this  entry can  be modified  for each  glass section  in the Zone Data
screen.  The height and width are important when determining the effect of a
shading device on a window.  If you do not have any overhangs or fins on the
window then  you can enter 1 as the height and width and enter the area into
the Zone  Data screen.   If  you do have shading devices on the window, make
sure the height of the glass is correct.                             ESD 710
                       Length of Horizontal Overhang

the building.   Just  the overhang itself is defined here; use the Zone Data
screen to  specify which windows the overhang occurs on.  Enter the distance
in decimal  feet that the overhang projects from the building.  The overhang
is assumed to project from the building at a 90 degree angle.        ESD 718
                Distance Beyond Right and Left Window Edge                  
   Enter the  distance in  decimal feet that the overhang extends beyond the
edge of  the window.   If you enter a zero (0) here, the overhang is assumed
to be exactly as wide as the window.                                 ESD 724
                           Distance Above Window

decimal feet.   Note  that this  distance is typically equal to the width of
the molding.                                                         ESD 728
                    Distance Right or Left Fin Projects                     
   Use this  entry to define the dimensions of any vertical fins that may be
on the  building.   Just the  fin itself  is defined here; use the Zone Data
screen to  specify which  windows the fins occur on.  Enter the distance the
fin projects from the building in decimal feet.                      ESD 732
             Distance of Right or Left Fin Beyond Window Edge               
   This entry  only applies  to left  or right  fins.   Enter  the  distance
between the  side of  the fin  and the  window itself in decimal feet.  This
distance is often equal to the molding of the window.                ESD 737
                        Height of Left or Right Fin                         
   This entry  only applies  to left  or right  fins.   Enter  the  distance
between the  top and bottom of each fin in decimal feet.  The top of the fin
is assumed to be flush with the top of the window.                   ESD 741
                         Air Handler System Number                          
   This input  item is used to number the air handlers so they can be easily
referred to  later.   You can  define up  to 99 air handlers per project and
they may  be created  in any  order (air  handler 22 can be enter first, for
example).  An additional feature of this input item is that if the number of
a air  handler which has already been entered (but is not being displayed on
the screen)  is entered  into this input item, then that air handler will be
displayed on  the screen.  So to see air handler #6, just type a 6 into this
data field.   Note  that the Pg Up key will display the previous air handler
and the Pg Dn key will display the next air handler.                 ESD 745
            Number of Times this System Occurs in the Building              
   This entry  is used to duplicate zones that access this air handler.  For
example, if you had defined three different zones under this air handler and
then specified that this system occurs twice in the building, the zone loads
for the  three zones  would be doubled for a total of six zones.  Zones that
used other  air handlers  would not  be affected.   Note  that you  can also
duplicate individual zones at the zone level.  Entering a zero in this field
deactivates this air handler and all the zones that reference it are skipped
when performing calculations.                                        ESD 755
                          Air Handler Description                           
   This input allows you to enter a specific description for the type of air
handling system  being used.   Some examples of air handler descriptions are
Standard VAV,  VAV with Reheat, and Constant Volume.  Note that if some kind
of air  handling system  is not  being  used,  it  is  acceptable  to  enter
descriptions such as "Baseboard Heating Only".                       ESD 764
   Enter 1 If Using Constant Volume Terminals, 2 For Variable Air Volume    
   If the  air handling  system is  being used  for cooling purposes then it
will provide  either a  constant volume  of air  or it  will be  capable  of
varying the  air volume  handled (VAV).   CHVAC  uses different  methods for
determining  zone   air  quantities   depending  on  the  air  system  type.
Therefore, be sure to respond accurately.                            ESD 770
     If CV, Enter 1 to Proportion Supply CFM, 2 to Sum Peak Zone CFMs       
   If the  air handler  is using  a constant  volume of air (meaning the air
handler cannot  vary its  air volume) then you must specify whether the zone
air quantities  will be  based on a proportioned amount of air or the sum of
the peak  requirements.   The proportioned CFM method determines the maximum
supply CFM  required by  all the  zones together and proportions this amount
back to  the individual  zones based  on their  peak loads.   The sum of the
peaks CFM method determines the maximum supply CFM required for each zone at
the its  individual peak  time and sums these maximum requirements together.
Note that  different zones  usually have different peak times, so you if you
sum the  peaks the  system as a whole will normally provide more air than is
ever necessary for the zones.  However, when the proportioned method is used
each zone  is usually  undersupplied during  the time of its peak load.  The
choice is up to you.                                                 ESD 776
    Enter 1 For Draw-Thru Fan, 2 For Blow-Thru Fan, 3 For Packaged Fan      
   Enter "1"  for this  input item if the supply air fan of the air handling
unit DRAWS air through the cooling coil (and is located on the supply side).
Enter "2"  if the  fan BLOWS air through the cooling coil (and is located on
the return side).  Enter "3" if the supply fan is part of a packaged unit or
if no supply fan is used.                                            ESD 790
          Enter 1 if Exhaust Air Can Exceed Supply Air, 2 if Not            
   The supply air is either calculated by the program or entered directly by
the user.  In addition, you are allowed to enter an exhaust air CFM for each
zone.   This entry  is used  in cases  where the  exhaust air  entered for a
particular zone  is greater  than the supply air amount.  Enter a "1" if you
want the program to allow negative pressurization for the zone.  Enter a "2"
if you  want the program to artificially increase the total supply air until
the supply air for THAT ZONE equals the exhaust air amount entered.  ESD 796
      Excess Supply Air:  1-Reheat, 2-Reserve Capacity, 3-Adjust Coil       
   This entry is used when the amount of supply air is greater than required
to meet  the building  loads.   It simply  tells the program how you want to
handle such  a situation  so that  subcooling of zones is avoided.  The most
common method  is method "2" which balances the extra CFM with an additional
gain on  the supply side of the coil and calls that gain "Reserve Capacity",
indicating the  air handler  has a greater capacity than needed by the zones
at this time.  The gain can also be called "Reheat" (option "1"), indicating
that the  air is  physically heated  before it  enters the  zone to  prevent
subcooling.   The least  common way  to deal with extra supply air is option
"3" which adjusts the temperature of the air leaving the cooling coil.  Note
that using method 3 could result in supply air of 60 or 65 degrees depending
on the amount of extra supply air.                                   ESD 804
    Enter Leaving Heating Coil Temperature or Total Heating Supply CFM      
   This input  allows you  to enter  either a  leaving heating coil dry bulb
temperature (LDB)  in degrees  F or  a total  heating supply  CFM  quantity.
Enter an  LDB temperature (usually between 90 and 200 deg F) for those cases
where you  want CHVAC  to calculate  the necessary  supply air  CFM for  the
project.  Enter a total CFM value of at least 200 CFM or greater if you have
a particular  supply CFM  that you  want CHVAC  to use.   If a value of 0 is
input, then the program sets it to satisfy the cooling supply CFM.   ESD 817
         Cooling Coil Input:  1-Dry Bulb Temp, 2-Relative Humidity          
   Enter either  a 1  or 2  to indicate  the method you would like to use to
specify the  leaving conditions  of the cooling coil.  Then enter the actual
value.   A typical  leaving coil  dry bulb temperature is 55 degrees F and a
typical leaving coil relative humidity is 95 percent.                ESD 825
                        Cooling Coil CFM (Optional)                         
   If you know the supply air the air system can provide, you can enter that
value here.  When this value is blank, CHVAC will calculate the required CFM
based on  either the  dry bulb temp or the relative humidity.  When a CFM is
entered, CHVAC  will attempt  to honor both the supply air specified and the
temperature or  relative humidity.   Note  that if the CFM specified here is
LESS than necessary it will be ignored.                              ESD 830
              Miscellaneous Btuh Gain - Supply or Return Side               
   This entry  is used  to account  for miscellaneous loads that are felt at
the air  handler level  - such as booster fans or other equipment on the air
handler system  itself.   If you  have such loads, enter them in Btuh on the
appropriate place, either the supply or return side.                 ESD 837
          Combined Fan and Motor Efficiency of Air Handling Unit            
   This input  is pertinent only if the supply fan is not part of a packaged
unit.   This is  because the  fan/motor heat gain has already been accounted
for in  the tonnage rating of a packaged unit.  Assuming that the supply fan
is not  part of a packaged unit and that only the fan itself (not the motor)
is positioned  in the air stream then you should enter the efficiency of the
fan alone  (usually from 60 to 85%).  If both the fan and motor are situated
within the  air stream,  you should  enter the combined fan/motor efficiency
which is the product of the fan and motor efficiencies.              ESD 842
      Static Pressure in Inches of Water Gauge (W.G.) Across the Fan        
   This input  is pertinent only if the supply fan is not part of a packaged
unit.   Assuming that  the supply  fan is  not part  of a packaged unit then
CHVAC must  know the  static pressure  in inches  of water across the fan in
order to determine the fan/motor heat gain.  This static pressure difference
typically ranges from 2 to 3 inches of water.                        ESD 851
               Anticipated Temperature Rise/Drop in Ductwork                
   This value  refers to  the heat  loss or heat gain that is experienced by
the air  entering the supply ducts and/or air leaving the system through the
return ducts.  This typically occurs when the ductwork is exposed to outside
air or  an unconditioned space.  Typical values that can be used for compar-
ison are  shown below.   Note  that these values do not cover every possible
combination of  insulation and  duct construction  and  should  be  used  as
general guidelines only.

                 Chilled/Hot Water Temperature Difference                   
   If a  chilled/hot water  system is to be used for this project, CHVAC can
calculate the  required water flow rate through the cooling/heating coils if
it knows what the expected temperature difference (TD) of the water entering
and leaving the coil is.                                             ESD 873
              Infiltration and Ventilation Methods and Values               
   CHVAC allows  three different  methods for adding outside air whether its
for ventilation  or infiltration.   Note that due to seasonal variations you
can describe  different summer (cooling) and winter (heating) rates for both
infiltration and  ventilation.   Ordinarily, a  system would  not have  both
infiltration and  ventilation, although  CHVAC  is  capable  performing  the
calculations.  These methods are described below.  Select the desired method
by entering the appropriate number.                                         
¡á                                                                          
°1ðMethod one  indicates that  air is  to be added on an air change per hour
basis.  Typical values range from 0.1 to 2.0 while 0.5 is most common.      
                                                                            
°2ðA CFM  per person  basis will be used.  Typical values range from 5 to 30
CFM per person for ventilation air while 10 CFM per person is common.       
                                                                            
°3ðMethod three  indicates that  air is to be added on a CFM per square foot
basis.  Typical values range from 0.1 to 1.0 CFM per square foot.    ESD 878
    Enter 1 If Ventilation Air Is Equal To 100% of Supply Air, 2 If Not     
   In the event that the supply air is to be 100% outside air, enter "1" for
this input, otherwise enter "2".  100% ventilation now applies to heating as
well as cooling.                                                     ESD 895
             Indoor Dry Bulb Temperature and Relative Humidity              
   Enter the new indoor design dry bulb temperature and/or relative humidity
you want  for this  system.  If you leave this value as zero, the previously
entered values (shown to the right) will be used.                    ESD 899
                  Enter 1 if Using Pretreated Outside Air                   
   If the  outside air is pretreated before it is mixed with the return air,
indicate here by typing a "1".                                       ESD 903
                    Enter 1 to Ignore Pretreating Load                      
   Normally, when  outside air  is pretreated, energy must be used to change
the temperature.   The CHVAC program will account for the additional load on
the Building level reports unless you type a "1" here.               ESD 906
        Summer Dry Bulb and Wet Bulb Temperature of Pretreated Air          
   Enter the  summer dry bulb and wet bulb temperature of the pretreated air
before it is mixed with the return air.                              ESD 910
                                Zone Number                                 
   This input  item is  used to  number the  zones so  they  can  be  easily
referred to  later.   The number  of zones you can create depends on whether
you have  the 2,  10, 50,  100, or  unlimited zone  version of  the program.
Also, the  demonstration version  of the program is limited to 2 zones.  The
zones must  be defined  in sequence.  For instance, zone 2 cannot be entered
until zone  1 is  defined.  An additional feature of this input item is that
if the  number of  a zone  which has  already been entered (but is not being
displayed on  the screen)  is entered  into this  input item, then that zone
will be  displayed on  the screen.   So  to see  zone #6  (if  it  has  been
defined), just  type a 6 into this data field.  Note that the Pg Up key will
display the previous zone and the Pg Dn key will display the next sequential
zone.   You also  have the  option of entering zone numbers of zero (0) when
creating new  zones and  the program  will  automatically  assign  the  next
sequential number to each zone.                                      ESD 913
                   Air Handler System Number - Zone Data                    
   Enter the Air Handler System Number for this zone here.  They are defined
on the Air Handler Data Screen (Master Menu Selection 6).            ESD 928
                           Zone Length and Width                            
   The length  and width  of  the  zone  are  entered  in  feet  and  should
correspond to  the CONDITIONED area of the zone.  In cases where the zone is
not rectangular  and it  is not  possible to give a single width and length,
you should  consider entering  the width  as 1  foot and  the length  as the
actual area.   The  main point  to remember is that the product of the floor
length and width entries should be equal to the actual floor area.   ESD 931
                             Number of People                               
   This input  allows you  to enter the number of people that will typically
occupy this  zone.   Normally you  should enter the maximum number of people
you expect  to occupy  the zone  during the cooling season.  The People Load
Profile is  used to  account for  less than  the maximum  number  of  people
occupying the  zone at the time of peak transmittance loads while the People
Diversity Factor adjusts the number of people in the building (NOT the zone)
to account for people moving from zone to zone.  Specify zero people (-1) in
zones that  are normally  unoccupied when  heat loads and solar loads are at
their peak.   If you enter "0", the program will automatically calculate the
number of  people based  on the  "Square Foot per Person" entry given in the
General Project data.                                                ESD 938
                                 Zone Name                                  
   This input  allows you  to enter an alphanumeric description for the zone
containing up to 20 characters.                                      ESD 950
                       Lighting and Equipment Watts                         
   This input  item allows  you  to  enter  the  watts  of  lighting  and/or
equipment in  the zone.   If  the total amount of watts is known, enter that
amount here.   Enter  "0" (zero)  watts to  have the  program calculate  the
number of  lighting or  equipment watts based on the "watts per square foot"
entry given in the General Project Data screen.  Enter "-1" to use a load of
zero (for  equipment, for example, that was not used during the summer).  Be
sure to  reduce the  equipment watts by some appropriate fraction to account
for intermittent use.                                                       
FLUORESCENT LIGHTS:  If you are using fluorescent lights you should multiply
the total  lighting watts  by the  Ballast Multiplier  shown below.  See the
User's Manual for further explanation.

   These inputs in feet are provided so that CHVAC can automatically compute
the area  of the  roof.   However, in  cases where  the roof  section is not
rectangular and  it is  not possible  to give  a single width and length you
should consider  entering the  width as  1 foot and the length as the actual
area.  The main point to remember is that the product of the roof length and
width entries  should equal to the actual roof area.  Note that if you enter
a glass  section with a tilt of 180 degrees (a horizontal skylight) the area
of the skylight will be subtracted from the roof.                    ESD 970
                 Height and Width of Partitions and Walls                   
   These inputs in feet are provided so that CHVAC can automatically compute
the gross  area of  partitions and walls.  However, in cases where it is not
possible to  give a single width and length you should consider entering the
width as  1 foot and the length as the actual gross area.  The main point to
remember is that the product of the length and width entries should be equal
to the  gross area.    Note  that  CHVAC  will  automatically  subtract  the
appropriate glass areas for each wall If the wall is 100% glass, then only a
direction for  the wall  is sufficient.   (partitions  do not have windows).
                                                                     ESD 979

   This input  requires you to enter the direction the wall faces or "P" for
a partition.   You  can enter  either a number or a letter designation.  All
360 degrees  are available  as wall  directions and can be entered in number
format (like  "90" for "East").  You can also enter a letter designation for
the 16 points on the compass.  The valid abbreviations are shown below.

   Enter the  tilt of  the glass  in degrees in degrees from the horizontal.
For example,  vertical glass  would have  a tilt  of  90  degrees,  while  a
horizontal skylight  would have  a tilt  of 180  degrees.   Note that if you
enter a  tilt of  180 degrees, the area of the glass will be subtracted from
the reference roof, rather than from the reference wall.             ESD1001

   If the  area of  this glass  section is  exactly equal  to the Height and
Width entries  on the  Master Glass Data screen you should enter a "1" here.
If the  Height and  Width are equal to "1", you should enter the total glass
area here.   Note  that if you are using EXTERNAL SHADING, the actual height
and width of the glass section is critical.  If you enter a quantity greater
than "1",  CHVAC assumes  the you have that number of SEPARATE windows, each
with its  own external  shade.   If you  enter a quantity less than "1", the
fractional quantity  will by  multiplied by  the width  entry only  and  the
height will  remain unchanged.   For  example, suppose  you had two banks of
windows under a common overhang that were dimensioned 15 x 5 feet and 25 x 5
feet.   The easiest way to handle this situation would be to enter a 100 x 5
foot glass  section in  the Master Glass screen and enter a Quantity of 0.15
for the  first group  of windows and a Quantity of 0.25 for the second group
of windows.                                                          ESD1007
                      Wall Reference for Glass (REF)                        
   Enter the  wall number  (1-10) on  which this  glass section  resides, or
enter the  roof number  (1-2) if the glass is a skylight.  If the glass is a
skylight, the tilt must be 180 degrees.  If the roof is 100% glass, then the
tilt is 180 degrees and reference can be left at zero. See your users manual
if this glass section constitutes the entire exposure.  If the wall is 100 %
glass, then reference the wall and only a direction for that particular wall
is required.  Note that if the glass is totally shaded, you should reference
it to  a NORTH  wall (if your city is in the northern hemisphere) or a SOUTH
wall (if your city is in the southern hemisphere) irrespective of its actual
wall direction.  Please note that partitions cannot have windows.    ESD1022
              Number of Times this Zone Occurs in a Building                
   The usual  value for this input is "1".  However, if you have a zone that
is repeated  frequently throughout the building, such as an office with just
internal loads,  rather than  inputting it  over and  over again, you should
input it  just once,  then using this input declare how many times it occurs
in the  building.   Note that if you wish to deactivate a zone such that you
could use it again, you should enter that it occurs zero times.      ESD1033
       Length in Feet of the Edge of the Floor Slab that is Exposed         
   If the  floor of  this zone  is concrete  slab on  grade, then  enter the
length in feet of the perimeter of the floor slab that is part of this zone.
Otherwise enter "0" (zero).  This entry will be used in conjunction with the
"Floor Heat  Loss Coefficient  for Exposed  Slab Perimeters"  field  in  the
General Project Data screen.                                         ESD1040
            Area of the Ceiling Exposed to a Return Air Plenum              
   If this  zone is directly beneath a return-air plenum then you must enter
the area  of the  ceiling that  constitutes the floor of the plenum area.  A
value of  zero will  cause the  area of the zone to be used.  Enter negative
one (-1) if NONE of the zone is directly beneath the plenum.  There may also
be cases where the plenum only affects a portion of the zone's ceiling.  The
sum of  all the  ceiling areas  exposed to  a return  air plenum will be the
calculated floor area of the return air plenum.  Note that if the ceiling of
this zone is beneath a plenum then the zone should NOT have a roof.  ESD1046
     Enter 1 For Cooling Load Calculations, 2 For Heating, 3 For Both       
   Enter a  1, 2,  or 3  if you  wish this zone to be calculated differently
from what was specified on the Air Handler Data screen.              ESD1055
                              Ceiling Height                                
   This input  allows you to change the ceiling height for this zone.  Enter
the new  height in  feet or  leave this  value as  zero to  use the  default
ceiling height shown on the General Project Data screen.             ESD1058
               Sensible, Latent, and Heating Safety Factors                 
   These inputs  allow you  to specify  what percentage  of the  HVAC  loads
(whether its  sensible gain,  latent gain, or winter heating loss) should be
added as a safety factor.  An entry of a whole number from 0 to 50 indicates
you want  to use  a safety  factor different  from the  one entered  on  the
General Project Data screen.                                         ESD1062
         Ventilation and Infiltration CFM for Cooling and Heating           
   Although you  may have  specified a  default basis  for  computing  these
outside air requirements, you can override the computed values for this zone
by directly entering the CFM of outside air that you desire.         ESD1068
                              Exhaust Air CFM                               
   Enter the  CFM of  air, if  any, that  is exhausted from the zone.  It is
possible that  you can enter so much exhaust air that it exceeded the supply
air required by the system.  If this ever becomes the case the analysis will
convert to  a 100% outside-air analysis.  Note that at the zone level excess
exhaust air can be replaced by supply air from other zones, causing negative
pressurization.   At the  air handler  level, exhaust  air  is  replaced  by
outside air.                                                         ESD1072
                        Latent BTUH Equipment Load                          
   This input allows you to enter a latent BTUH load for the zone.  Swimming
pools, fountains,  cooking equipment,  hair dryers, and other such items can
contribute latent heat gains.                                        ESD1080
                          Minimum Supply Air CFM                            
   If there  is a  minimum supply  air for this zone, then enter that amount
here.  The CFM entered will be ignored if it is not sufficient.      ESD1084
                             Source File Name                               
   Type the  name of the CHVAC project data file that contains the zone data
you wish  to copy.    Usually  the  source  filename  is  the  same  as  the
destination file  name.  If the source file name is on another drive besides
the one  on which  you are  logged, enter the source drive designation and a
colon, then enter the source project file name.                      ESD1087
                           Destination File Name                            
   Type the  name of  the CHVAC project data file that you wish to copy zone
data to.   Usually  the destination  filename is the same as the source file
name.   If the  destination file name is on another drive besides the one on
which you  are logged,  enter the source drive designation and a colon, then
enter the destination project file name.                             ESD1093
                 Beginning and Ending Source Zone Numbers                   
   You can  copy a  single zone by giving the same beginning and ending zone
number or  you can  copy a  range of  zones by  giving an ending zone number
greater than  the beginning  zone number.   However,  please note  that  the
ending zone  number cannot  be greater than the total number of zones in the
source project data file.                                            ESD1099
                          Destination Zone Number                           
   Enter the  zone number to which you wish the zone data to be copied.  THE
CURRENT CONTENTS OF THE DESTINATION ZONE WILL BE ERASED.             ESD1105
                         Enter 1 To Begin Copying                           
   After you have correctly specified the source and destination file names,
you can enter "1" to begin the copying procedure.                    ESD1108
         Rotation Degrees (Negative Numbers mean Counterclockwise)          
   Enter the  number of  degrees you want all the walls in the zone rotated.
For example, if you want all currently east facing walls and windows to face
west, specify  180 degrees  for the rotation.  If you wanted all west facing
walls and  windows to  face north,  you would  enter  -90  degrees  for  the
rotation.                                                            ESD1111
           Enter Beginning and Ending Zone Numbers for Rotation             
   A rotation  change can be performed for all zones at once, a single zone,
or any  range of zones.  Simply set the beginning and ending zone numbers as
desired.                                                             ESD1117
                         Enter 1 To Begin Rotation                          
   Enter 1 to perform the zone rotation as specified.                ESD1121
                               Plenum Number                                
   You can have up to 999 plenums per project.  Enter the appropriate plenum
number here.   Note  that the  air handler  number will  be the  same as the
plenum number.   For  example, plenum #2 will use air handler #2.  Note that
the air handler should NOT have any return air ductwork.             ESD1123
                        1 - Active, 2 - Not Active                          
   This entry is included to allow you to quickly "deactivate" the plenum if
you wish.   You  could decide to deactivate the plenum if you decided not to
use the  plenum in  the building  or if  you wanted  to run a set of reports
without the plenum and compare them to a set run with the plenum.    ESD1128
                     Percent of Lighting Load to Zones                      
   This entry  allows you  to enter  the percent  of the lighting loads that
should be  applied to the zones.  Enter a whole number greater than or equal
to 0  (zero) but  less than  100.   Note that  CHVAC takes the complement of
whatever you  enter as the percent of lights to the plenum.  For example, if
you specify  that 60%  of the  lighting load  is to be applied to the zones,
then CHVAC  knows that  40% is  to be  applied to  the plenum  space.  If no
return air  plenum has  been specified  then CHVAC  automatically  sets  the
percent of lighting loads to the zones as 100%.                      ESD1133
                         U-Factor of Plenum Floor                           
   The material  that separates  the plenum  area from the zones beneath the
plenum is  considered to  be the  plenum floor.  The plenum floor is usually
acoustic ceiling tile which has a U-Factor of about 0.31.            ESD1142
                            Watts of Equipment                              
   Enter the watts of any heat producing equipment located in the return air
plenum.                                                              ESD1146
                    Plenum-Zone Temperature Difference                      
   During the  cooling months  the temperature  in the  plenum area  will be
slightly higher  than the  temperature in  the zones  and during the heating
months the  temperature in  the plenum  area will be somewhat lower than the
temperature in  the zones.   The exact temperature difference depends on the
loads to  the plenum  and the  amount of  return air being moved through the
plenum.   This input  requires you  to estimate  the actual temperature dif-
ference that  will occur.  In the summer, differences typically range from 2
to 10  degrees F  while 5  degrees F  is common.  In the winter, differences
typically range  from 5  to 30  degrees F while 10 degrees F is common.  The
actual temperature  rise caused  by the  plenum for  a particular project is
shown on the Psychrometric report.                                   ESD1149
                            Enter Today's Date                              
   This input  is simply  for reference purposes.  You can enter the date in
any form you wish since letters and numbers are allowed.  We recommend using
a current date so you can refer to the report later.                 ESD1161
            Enter the Desired Starting Page Number for Reports              
   Since it is possible to print the various reports out separately, be sure
that you consider what starting page number is necessary to join the reports
so that  they have consecutive page numbers.  This entry is normally left at
"1".                                                                 ESD1165
            Enter the Number of Spaces for the Left Hand Margin             
   If the  reports are  being printed  on screen,  you should  specify  zero
spaces for  the left  margin.   If they are being printed on the printer you
will need to experiment with the number of spaces (usually 4 works fine) for
the left  hand margin,  so that  you obtain  proper margins.   The number of
spaces required  for balanced  left and right margins depends on the printer
you have, and how it is set up.                                      ESD1170
       Enter the Beginning and Ending Zone Numbers for Calculations         
   Usually you  want the  beginning and ending zone numbers to correspond to
the exact  number of zones that have been entered for the project.  However,
you may  specify any  range of  zones you  want for  calculation.   This  is
especially useful for the quick review of a single zone on screen.   ESD1177

         Enter 1 To Print the Detailed Zone Loads Report, 2 If Not          
   This report  prints a  detailed analysis  of the  individual heating  and
cooling loads on each zone.  It requires the program to perform computations
and contains  all the  necessary intermediate  values to  verify the printed
results.   It is  as many pages long as is needed to describe all the zones.
Enter a 1 to print this report, 2 if not.                            ESD1202
         Enter 1 To Print the Air System Summary Report, 2 If Not           
   This report is divided into two sections and is always at least two pages
long.  The two sections are: Zone Summary and Total Load Summary.           
                                                                            
   The AIR SYSTEM ZONE SUMMARY report prints for each air handler system the
minimum supply  air and  outside air  requirements for each zone, along with
each zone's  peak time.  The minimum required CFM values can then be used to
size the duct system.                                                       
                                                                            
   The AIR SYSTEM TOTAL LOAD SUMMARY report summarizes the loads on each air
system.   The loads  are grouped into four categories: total system sensible
loss, sensible  gain on supply side of coil, sensible gain on return side of
coil, and latent gain.  This report also shows the total supply air required
by the each system, the total gain, and the total required tonnage.         
                                                                     ESD1208
       Enter 1 To Print the Psychrometric Analysis Report, 2 If Not         
   This report  analyzes the  HVAC system  psychrometrically.   It lists for
each air  handler the dry bulb, wet bulb, relative humidity, and enthalpy of
the air  entering and  leaving the cooling coil.  The temperature of the air
entering and  leaving the  heating coil  is also  shown.  If a chilled water
system was  being used, the program will also list the necessary flowrate in
gallons per minute.                                                  ESD1223

   This input item is used to view the weather data of a particular city, to
specify a  new city,  or to  change the name of an existing city.  Note that
you should type the desired name right over the city that is already showing
in this  space, since  this entry  is used  to access the weather data file.
You can "page" through the cities with the "Pg Up" and "Pg Dn" keys.  Unlike
Master Menu  selection #2,  ANY CHANGES MADE TO THE WEATHER DATA (other than
"City and  State") SHOWN  WHEN MASTER  MENU SELECTION  W  IS  ACCESSED  WILL
PERMANENTLY CHANGE  THE WEATHER  DATA BASE.  See your User's manual, Chapter
9, for more information about this Master Menu selection.            ESD1247

   This field is optional and can be used to enter the date the weather data
was taken.                                                           ESD1257
                            Ground Reflectance                              
   The next  entry  requests  that  you  enter  the  ground  reflectance  if
different from 20%.  Note that you should always use a ground reflectance of
20% unless  the surface of the ground is radically different from normal (as
would be  the case with a building surrounded by water).  You do not want to
frivolously change  the ground  reflectance,  because  when  this  value  is
different from  20%, it  will change  the loads  of all  the windows  in the
entire job.

                             Clearness Factor                               
   For non-industrial  locations where  clear, dry skies predominate, and at
high elevations,  use the clearnes numbers shown in the map in the appendix.
Otherwise, use a clearness number of 1.                                     
                                                                            
   The clearness  number is  multiplied into  the maximum  solar  heat  gain
factors.  Therefore, it will have a direct impact on glass loads.    ESD1278
                               Rotate Plenum                                
   Enter a  1 to  rotate plenums associated with the zones in the zone range
specified.  Enter a 2 if only the zones are to be rotated.           ESD1285
                       Selection I - Install Program                        
 Use  this selection  to change  the color of the screens or the location of
the data  files.   The installation is performed when you press the (Escape)
key.   The program will prompt "OK to Install?".  Type a "Y" and the changes
will be performed.                                                   ESD1288
                            Zone Data Overview                              
   The Zone  Data Overview  screen shows an overview of defined zones.  Each
zone takes  up one  line on the screen so only partial information is shown.
This includes  air system  number, length, width, number of people, lighting
watts, number  of wall  entries, number  of glass entries and number of zone
occurrences.                                                                
                                                                            
   The cursor  keys can  be used  to scroll  the data  as needed.  Press the
(Escape) key  to return  to the zone you were previously editing.  Press the
(Enter) key to edit the selected zone.                               ESD1293
               Winter Dry Bulb Temperature of Pretreated Air                
   Enter the  winter dry bulb temperature of the pretreated air before it is
mixed with the return air.                                           ESD1303
                             Report File Name                               
   If you  choose to  print reports  to a  file, the  program uses this file
name.  All reports being printed get placed in this file.  The file is given
a ".CHR"  extension.  It is created on the drive you specify.  If this drive
is the  same  as  the  project  drive  then  the  file  is  in  the  project
subdirectory, otherwise it is in the "current" subdirectory.         ESD1306
                        Lotus Compatible File Name                          
   If you  specify a  file name  here and  then print  the Air  System  Load
Summary Report, the program will create a file with the given name and place
zone information  in that file.  This will be the same information that gets
printed as  the "Air  System Zone  Summary".  The file will be give a ".CHL"
extension.   It can be "imported" into lotus using the "Numbers" option.  It
is created  on the  drive you  specify.   If this  drive is  the same as the
project drive  then the file is in the project subdirectory, otherwise it is
in the "current" subdirectory.                                       ESD1312
                  Beginning and Ending Air System Numbers                   
   When you  first bring  up the Print Reports screen, these numbers are set
to zero.   The  program uses the beginning and ending zone numbers to select
the range  of zones  to print.   The  beginning and  ending zone numbers are
defaulted to print all zones.                                               
                                                                            
   If you  specify the  beginning and  ending air  system numbers,  then the
beginning and  ending zone  numbers are  ignored.   The program  only prints
zones associated with the air system range specified.                ESD1321
               Beginning and Ending Detailed Zone Load Hours                
   These number  are defaulted  to zero.   This  means that if you print the
Detailed Zone  Loads Report,  only the peak loads will be printed.  However,
if you  specify the  beginning and ending detailed zone load hours, then the
program will  also print detailed loads at each hour in the specified range.
Note that this may generate many additional pages of output!         ESD1330
                        Zone Sensible Load Profile                          
   This option  allows you  to print  a sensible  load profile for each zone
being calculated.   Sensible  loads are  printed for  each hour in the range
beging calculated  and all  specified design  months.   If the Detailed Zone
Loads are also being printed then the profile for each zone is printed after
the detailed loads.                                                  ESD1336
                      Air System Load Profile Report                        
   The Air  System Zone  Sensible Load  Profile Report  lists for  each  air
system the  total zone  sensible cooling  load at each operating hour of the
building for each design month.                                      ESD1342
                   Air System Load Profile Graph Report                     
   This is  a bar  chart representation of the air system sensible loads for
the building operating hour range.  One bar chart is printed for each design
month.                                                               ESD1346
                        Building Load Graph Report                          
   This is  a pie  chart representation  of the  building loads shown on the
Building Load  Summary Report.   Two  charts are  printed for total building
gain; one  shows detailed  and the  other shows  summary descriptions.   Two
charts are printed for total building loss in the same way.          ESD1350
                      1-EP9, 2-EP24, 3-LASER, 4-OTHER                       
   This selection  is important  if graphs  are  being  printed.    Improper
selection can  cause the  printer to  print garbled  output!   Enter "1"  to
select a 9 PIN Epson FX-80 or compatible printer (EP9).  Enter "2" to select
a 24  PIN Epson  FX-80 or compatible printer (EP24).  Enter "3" to select an
HP Laserjet or compatible printer.  If you enter a "4", the program will not
attempt to print the graphs to the printer.                          ESD1355
