D. Deadband (Step 6)
The deadband is the difference in temperature above the cool-
ing set point or below the heating set point that the ther-
mostat 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 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
2 degrees.
E. Set Point Minimum Difference (Step 7)
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 operation.
F. 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
5-minute compressor lockout is disabled or compressor
is allowed unlimited cycles. Do not set thermostat
Advanced Setup Step 8 to ‘‘d’’ or ‘‘dl’’ unless specifically
recommended for the application.
G. Dry Contact Configuration (Step 9)
The Dry Contact configuration is used to set the thermostat
dry contacts to normally open or normally closed. This should
be set to match the configuration of the external device (if
present).
If the configuration is set to normally open, the thermostat
will enter Unoccupied mode when the contacts close. If the
configuration is set to normally closed, the thermostat will
enter Unoccupied mode when the contacts open. The default
is normally open.
H. 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 Reset Filter button while
in Advanced 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. The set point is adjusted in inter-
vals of 50 hours. Set the variable to 0 to disable this function.
The default is 500 hours.
I. Soft Start (Step 12)
The soft start is used when multiple units are used in an
application. The soft start staggers the start up times of the
units in the event of power loss and restart. Each unit should
be assigned a unit ID number. The 30-second delay time is
multiplied by the unit ID number to get the total soft start
delay time for each unit. For example, if the unit ID number
is 10, set the Soft Start function to 10, the start up delay time
is 30 seconds x 10 = 300 seconds (5 minutes). The range is
0 to 99 (ID numbers). A value of 0 disables the function. The
default is 0 (ID number).
J. Fahrenheit/Celsius Operation (Step 13)
The thermostat can be set to operate in Fahrenheit or
Celsius degrees. Set the variable to ‘‘F’’ for Fahrenheit opera-
tion. Set the variable to ‘‘C’’ for Celsius operation. The
default is ‘‘F.’’
K. Sensor Type (Step 14)
The Sensor Type setting configures the thermostat for use
with a remote room sensor, outside temperature sensor, or
duct temperature sensor. The Sensor Type can be set to Yes
or No.
When the Sensor Type is set to Yes, the outside or duct tem-
perature can be viewed by pressing and holding the Mode
button for 2 seconds. If a sensor has not been installed, no
temperature will be displayed. The thermostat will not con-
trol to outside or duct temperature readings.
When the Sensor Type is set to No, the thermostat will
detect and use an installed sensor as a remote temperature
sensor to control thermostat operation. If a sensor has not
been installed, the thermostat will use its internal tempera-
ture sensor.
L. Security Level (Steps 15 to 17)
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 16 and 17. When the security level is
set to ‘‘2,’’ the set point range is limited by the settings of
Steps 16 and 17 and the thermostat operation mode cannot
be changed. When the security level is set to ‘‘3,’’ the set point
range is limited by the settings of Steps 16 and 17, the ther-
mostat operation mode cannot be changed, and set point
changes are prohibited. The default is 0.
Security Maximum Heat Set Point (Step 16)
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).
Security Minimum Cool Set Point (Step 17)
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).
V. INSTALL ACCESSORIES
The following accessories can be used with this thermostat:
• remote temperature sensor (TSTATBBPACC-WB)
• outdoor temperature sensor (TSTATBBPACC-01)
• duct temperature sensor (TSTATBBSEN-DS)
• Add-a-Wire™ accessory (TSTATBBPACC-AW)
Refer to the accessory installation instructions for more
information.
A. Remote Temperature Sensor
A remote temperature sensor may be provided to read the
temperature from a space. If a remote temperature sensor
is connected, the thermostat will ignore the reading of its
internal sensor. When the thermostat is using a reading from
a remote sensor, the degree symbol above the temperature
reading will blink. An Override button is provided with the
sensor.
