DEADBAND (Step 6) — The deadband is the difference in
temperature above the cooling set point or below the heating
set point that the thermostat will wait before turning on the
first stage of heating or cooling. For example, if the cooling
set point is 82 F (28 C) and the deadband is 2 degrees, the
first stage of cooling will not be energized until the tempera-
ture reaches 84 F (30 C). The range of values is 1 to 6 de-
grees. The default is 2 degrees.
SET POINT MINIMUM DIFFERENCE (Step 7) —The mini-
mum difference between heating and cooling set points can
be user-configured. The range is from 0 to 6 degrees. The
default is 2 degrees. The minimum difference is enforced
during Autochangeover and Program On operation.
CYCLES PER HOUR LIMIT (Step 8) — The number of
times that heating or cooling can be energized per hour can
be configured. Set the variable to ''d'' for no limit. Set the
variable to ''d1'' to disable the 5-minute compressor lock-
out. The variable can also be set from 2 to 6 cycles per hour.
The default is 6 cycles per hour.
Damage to compressor could result if 5-minute com-
pressor lockout is disabled or compressor is allowed un-
limited cycles. Do not set thermostat Advanced Setup
Step 8 to ''d'' or ''dl'' unless specifically recom-
mended for the application.
BACKLIGHT DISPLAY (Step 9) — The display backlight
can be set to ON (always on) or OFF (turn off 8 seconds
after usage). The default is ON.
SERVICE FILTER (Steps 10 and 11) — Step 10 allows the
user to reset the Service Filter counter to zero and remove
the ''SERVICE FILTER'' icon (if displayed on the thermo-
stat screen). Press the FAN button while in Setup Step 10
and the counter is reset to zero. Press the Mode button to
adjust the number of hours the blower will run before the
''SERVICE FILTER'' icon is displayed. The range is 0 to
1950 hours. Set the variable to 0 to disable this function.
The default is 500 hours.
FAHRENHEIT/CELSIUS OPERATION (Step 12) — The
thermostat can be set to operate in Fahrenheit or Celsius de-
grees. Set the variable to ''F'' for Fahrenheit operation. Set
the variable to ''C'' for Celsius operation. The default is ''F.''
SECURITY LEVEL (Steps 13 to 15) — The Security Level
limits the actions that the user can perform at the thermostat.
There are 4 security levels. When the security level is set to
''0,'' no security will be in effect. When the security level is
set to ''1,'' the set point range is limited by the settings of
Steps 14 and 15. When the security level is set to ''2,'' the
set point range is limited by the settings of Steps 14 and 15
and the Program On mode is always in effect. When the se-
curity level is set to ''3,'' the set point range is limited by the
settings of Steps 14 and 15, the Program On mode is always
in effect, and set point changes are prohibited. The default
is 0.
Security Maximum Heat Set Point (Step 14) — If the Se-
curity Level is not set to 0, the maximum heating set point
will be in effect. The user will not be allowed to set the heat-
ing set point over the specified value. The range of values is
35 to 99 F (1 to 37 C). The default is 80 F (27 C).
Security Minimum Cool Set Point (Step 15) — If the Se-
curity Level is not set to 0, the minimum cooling set point
will be in effect. The user will not be allowed to set the cool-
ing set point below the specified value. The range of values
is 35 to 99 F (1 to 37 C). The default is 65 F (18 C).

Program Thermostat Schedules —
gramming the thermostat, plan the thermostat daily sched-
ule. The schedule is divided into 7 days (Monday through
Sunday). Each day has from 2 to 4 time periods (Occupied
1, Occupied 2, Occupied 3, Unoccupied) depending on the
configuration of the thermostat. Each occupied time period
has a start time, stop time, heating set point, and cooling set
point. The unoccupied time period has a heating set point
and a cooling set point. The unoccupied time period is active
when ever an occupied time period is not active. Fill in
Table 3 as an aid to programming the daily schedules.
PROGRAMMING MODE — To program the daily sched-
ules, perform the following procedure:
1. Enter programming mode by pressing the Program but-
ton. The Occupied 1 annunciator will appear on the ther-
mostat display. Use the UP ARROW and DOWN AR-
ROW buttons to set the maximum number of Occupied
periods for each day. The thermostat can be set to 1, 2,
or 3. After the number of Occupied periods has been
selected, press the Mode button. See Fig. 5.
2. The cooling set point for Occupied 1 will be displayed.
Use the UP ARROW and DOWN ARROW buttons to
raise or lower the cooling set point until the desired tem-
perature is shown. The range of acceptable values is 35
to 99 F (1 to 37 C). Press the Mode button to continue.
See Fig. 5.
3. The heating set point for Occupied 1 will be displayed.
Use the UP ARROW and DOWN ARROW buttons to
raise or lower the heating set point until the desired tem-
perature is shown. The range of acceptable values is 35
to 99 F (1 to 37 C). Press the Mode button to continue.
