B. Electric Heat Conﬁguration (Step 5)
Security Maximum Heat Set Point (Step 14)
Step 5 is used to conﬁgure the thermostat for electric heat.
The variable can be conﬁgured ON or OFF. The default is
If the Security Level is not set to 0, the maximum heating
set point will be in effect. The user will not be allowed to set
the heating 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).
NOTE: Step 5 will appear only if Step 3 is set to OFF.
Security Minimum Cool Set Point (Step 15)
C. Deadband (Step 6)
If the Security Level is not set to 0, the minimum cooling set
point will be in effect. The user will not be allowed to set the
cooling set point below the speciﬁed value. The range of val-
ues is 35 to 99 F (1 to 37 C). The default is 65 F (18 C).
The deadband is the difference in temperature above the
cooling set point or below the heating set point that the ther-
mostat will wait before turning on the ﬁrst stage of heat-
ing or cooling. For example, if the cooling set point is 82 F
28 C) and the deadband is 2 degrees, the ﬁrst stage of cool-
ing will not be energized until the temperature reaches 84 F
30 C). The range of values is 1 to 6 degrees. The default is
VI. INSTALL ACCESSORIES
The following accessory can be used with this thermostat:
Add-a-Wire™ accessory (TSTATBBPACC-AW).
D. Set Point Minimum Difference (Step 7)
Refer to the accessory installation instructions for the acces-
sory for more information.
The minimum 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 dur-
ing Auto-Changeover and Program On operation.
VII. PROGRAM THERMOSTAT SCHEDULES
Before programming the thermostat, plan the thermostat daily
schedule. 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 con-
ﬁguration 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.
E. Cycles Per Hour Limit (Step 8)
The number of times that heating or cooling can be ener-
gized per hour can be conﬁgured. Set the variable to ‘‘d’’ for
no limit. Set the variable to ‘‘d1’’ to disable the 5-minute com-
pressor lockout. The variable can also be set from 2 to 6 cycles
per hour. The default is 6 cycles per hour.
CAUTION: Damage to compressor could result if
-minute compressor lockout is disabled or compressor
NOTE: When the sensor detects light (the space is occupied),
the thermostat will enter Occupied 1 mode. If the room is
dark, the thermostat will follow its programmed schedule.
The Occupied 1 schedule should be turned OFF to keep the
thermostat from entering Occupied 1 while the room is un-
occupied. If the Occupied 1 schedule is turned ON, the ther-
mostat will enter Occupied 1 per the schedule regardless of
light activation. The Occupied 1 set points are used as the
heating and cooling set points during light activation. The
Unoccupied set points should be used as non-work hour set
points (before 8:00 AM and after 5:00 PM) when using light
activation. For times when the building is unoccupied during
work hours (Monday through Friday, 8:00 AM to 5:00 PM),
the Occupied 2 schedule should be turned ON, and can be
used for moderate energy savings with set points of 80 F for
cooling and 65 F for heating.
is allowed unlimited cycles. Do not set thermostat
Advanced Setup Step 8 to ‘‘d’’ or ‘‘dl’’ unless speciﬁcally
recommended for the application.
F. 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.
G. 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 thermostat screen). Press the FAN button while in Setup
Step 10 and the counter is reset to zero. Press the Mode but-
ton to adjust the number of hours the blower will run before
the ‘‘SERVICE FILTER’’ icon is displayed. The range is 0 to
950 hours. Set the variable to 0 to disable this function. The
A. Programming Mode
default is 500 hours.
To program the daily schedules, perform the following
H. Fahrenheit/Celsius Operation (Step 12)
. 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
ARROW 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.
The thermostat can be set to operate in Fahrenheit or Cel-
sius degrees. Set the variable to ‘‘F’’ for Fahrenheit opera-
tion. Set the variable to ‘‘C’’ for Celsius operation. The default
I. Security Level (Steps 13 to 15)
The Security Level limits the actions that the user can per-
form 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 ef-
fect. When the security 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 prohib-
ited. The default is 0.
. 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
temperature is shown. The range of acceptable values
is 35 to 99 F (1 to 37 C). Press the Mode button to con-
tinue. See Fig. 5.
