TB7100A1000 MULTIPRO™ MULTISPEED AND MULTIPURPOSE THERMOSTAT
19 63-2675—03
Special Programmable Mode Functions
Installer Setup 160 allows the thermostat to be configured for
either a mode with a programmable 7 day schedule or as a
non-programmable thermostat.
Preoccupancy purge (ISU 185)
This feature is available only when the thermostat is configured
as a programmable schedule and when a fan is used. The fan
will run 1-3 hours before the occupied schedule starting time to
circulate air.
Override Button, Temporary Override (Duration Limit ISU
535)
While in the programmable schedule mode, an override button
is available to perform temporary override control. The default
override time can be configured through ISU 535. Lockout
configuration via ISU 670 can provide restrictions on access to
setpoint changes, system changes, and schedule changes.
No remote setback
The remote setback feature only works in the non-
programmable mode.
Special Non-Programmable Mode Functions
Override (Optional)
The override feature is optional in the non-programmable
mode. The override can be configured through ISU 342. When
the override is activated in the non-programmable mode it will
temporarily override to a new setpoint until the end time
expires.
Remote Setback
Remote Setback is available (ISU 340). Occupancy sensors,
manual time clock inputs, and DDC night setback can be used
to provide inputs to setback the thermostat. Unoccupied
heating (ISU 343) and unoccupied cooling (ISU 346) setpoints
are available to configure the setback setpoints.

Setting Temperature Overrides

There are three temperature override options:
— Hold Temperature Until
— Override, and
— Holiday.
HOLD TEMPERATURE UNTIL
Holds the temperature temporarily until the time set by the
user, or the next scheduled period time.
1. Press the Up or Down arrow next to the temperature to
adjust. The Hold Until time appears on the screen. The
time defaults to the next scheduled period start time
2. Press NEXT to adjust the time for the thermostat to
resume schedule.
NOTE: The installer setup can limit the length of time
for an override to 1, 2, 3, or 4 hours beyond the
current time.
3. Press DONE or wait 5 seconds.
4. Press CANCEL or SCHEDULE to cancel “Hold Tempera-
ture Until” and resume the schedule.
OVERRIDE
Changes temperature setting until the next period takes effect.
For use during Unoccupied periods.
1. Press OVERRIDE. The settings change by default to the
next Occupied period.
NOTE: Changes are limited to those allowed by the
lockout level.
2. Press Up or Down arrow to change the override temper-
ature, and NEXT to adjust override time.
HOLIDAY
Changes temperature setting for a designated number of days.
Press MORE and then HOLIDAY. The screen shows “Hold
Until 1 DAYS”.
1. Press Up or Down arrow to change the temperature
desired for the thermostat to override the schedule.
2. Press NEXT to change the desired days for the duration
of the holiday.
3. To cancel the Holiday Override early, press CANCEL.

Fan Status Displayed on Main Screen

When the thermostat is running the fan, the fan blade symbol
appears next to FAN to indicate the thermostat has the fan
on.
NOTE: If the thermostat is not controlling the fan—typical for
many gas, forced-air heating systems—the fan blade
symbol will not appear even though the fan may
be running.

Replacing Batteries

Not all thermostat models require batteries. If the thermostat
has batteries, a low battery warning (see Fig. 38) flashes on
the main screen for approximately 30 days.
NOTE:
— If batteries are not replaced when the Low Battery
warning is flashing, the LO batt screen displays
continuously and the thermostat stops operating
until batteries are replaced.
— The thermostat has a low battery indicator.
However, it is recommended that the batteries be
replaced once each year. Do this to prevent
leakage and prevent the thermostat and HVAC
system from shutting down due to lack of
thermostat battery power.
