1.
When used in a single-transformer system, leave
metal jumper wire in place between Rc and R. If
used on a two-transformer system, remove metal
jumper wire between Rc and R.
Common wire is optional when thermostat is used
with batteries. When using separate transformers
for heating and cooling, the common must come
from the cooling transformer.
If thermostat is configured for a heat pump in the

TB7100A1000 MULTIPRO™ MULTISPEED AND MULTIPURPOSE THERMOSTAT
OPERATION
Fan Sequence Operations (ISU 347, 348, 349)
If heat pump or conventional application modes are enabled in
ISU 170, then ISU 347 is not available for fan ramp algorithm.
The fan operates as a default ON/AUTO selection that works
the same way as our CommercialPRO TB7220 thermostat.
There is only one fan relay output that is activated.
If PTAC or fan coil thermostat application modes are enabled in
ISU 170, then ISU 347 fan ramp algorithm is available for
installer setup selection. The fan ramp algorithm will
automatically calculate the appropriate fan speed that is
needed to meet the proportional band requirements to speed
up setpoint satisfaction. When the setpoint is satisfied it will
revert to the lowest fan speed setting to conserve energy.
The thermostat comes factory default with the fan ramping
algorithm enabled (ISU 347). This gives the user the ability to
select Auto-Lo-Med-Hi option in ISU 348 or Auto only option in
ISU 348. Auto sets the thermostat into the fan ramping
algorithm mode and automatically sets the sufficient speed for
PI control. Auto also automatically shuts the fan off when there
is not a call for heating or cooling. If the user decides to disable
ISU 347, then the fan will only have Lo-Med-Hi option
available.
If ISU 347 is not enabled, then ISU 348 does not appear as a
user selection choice.
If ISU 347 is enabled, then ISU 349 is available as a selection
choice. The user can select either a 2 hour or 4 hour timer fan
reset function. The fan will reset from a constant on speed to
Auto mode after the time period expires. If ISU 347 is not
enabled, then ISU 349 does not appear as a user selection
choice.
Equipment Sequence Operations (ISU 170)
Heat Pump and Conventional
Heat Pump and conventional use a single fan speed. The
single fan speed label is the G terminal relay output. Display on
the thermostat for these modes will give the Fan On/Auto
option. There is no fan ramping algorithm, ISU 347, 348, 349
are not available.
sensor enabled, the thermostat screen system mode will lock
on heat or cool (whatever the changeover sensor is
communicating to the thermostat). If ISU #340 does not have a
changeover sensor enabled, then the system mode from the
thermostat screen can manually be adjusted between heat or
cool. It follows the fan sequencing described above with ISU
347, 348, 349.
2 pipe with reheat - 2 pipe modes do not contain the ability to
have automatic changeover. They are manual changeover
only. The thermostat will have a priority when choosing a
system mode (heat or cool). When ISU #340 has a 2 pipe
changeover sensor enabled, the thermostat screen system
mode will lock on heat only. When the 2 pipe changeover
sensor is sensing cool mode, the user can adjust to heating
mode which will bring on the auxiliary heat. If ISU #340 does
not have a changeover sensor enabled, then the system mode
from the thermostat screen can manually be adjusted between
heat or cool. It follows the fan sequencing described above
with ISU 347, 348, 349.
Operating Sequence
The thermostat energizes specific terminal(s), depending on
the demand for heating, cooling or fan. The thermostat screen
shows the time, inside temperature, system and fan selections.
Additional indicators are shown when the heating, cooling or
fan is energized. See Tables 8 and 9 for specification
information.

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 nonprogrammable mode.
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
2.
Press Up or Down arrow to change the override temperature, 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.
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:
—
There are three temperature override options:
— Hold Temperature Until
— Override, and
— Holiday.
—
HOLD TEMPERATURE UNTIL

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.
NOTE: The installer setup can limit the length of time
for an override to 1, 2, 3, or 4 hours beyond the
current time.

Temperature Recovery
The thermostat is equipped with a feature to eliminate
guesswork when setting a schedule. That is, the user need not
know the amount of time for the HVAC system to bring the
space to temperature (without overshoot) prior to the
scheduled time.The thermostat manages that automatically.
Simply set the program schedule to the desired time to have
the space at comfort temperature. In addition, program the
temperature to this comfort temperature. The thermostat
activates the heating or cooling at the proper time to reach the
scheduled temperature at the scheduled time.
NOTE: The setpoint changes gradually to use economical
stages and avoid overshoot.
For best results, allow C7189U Wall Mount Temperature
Sensor to absorb the air moving through the room for a
minimum of twenty minutes before taking a resistance
measurement.
With an accurate thermometer (±1°F [0.5°C]) measure the
temperature at the sensor location, allowing time for the
thermometer to stabilize before reading.
To verify sensor resistance, remove one wire from one of
C7189U wiring terminals. Use an ohmmeter to measure the
resistance across the sensor. Then compare sensor accuracy
with the temperature/resistance curve in Fig. 40.
220K
For example—the space will be occupied at 8:00 AM and the
desired temperature is 70°F. Set the OCC 1 period for 8:00 AM
and 70°F. The thermostat turns on the heat prior to 8:00 AM to
raise the temperature to 70°F by 8:00 AM.
190K
RESISTANCE (OHMS)
160K
The thermostat provides an alert that the heating or cooling
system is coming on before a scheduled time by displaying
“Recovery” on the screen.
Minimum-Off Timer Compressor Protection
The thermostat has an adjustable Minimum-Off Timer that can
be set from zero to five minutes (Factory Setting—five
minutes). The Minimum-Off Timer can be bypassed through
the Installer System Test or it can be bypassed permanently by
setting the Minimum-Off Timer to 0 minutes in the Installer
Setup. The Minimum-Off Timer is activated after the
compressor turns off:
— If the thermostat is system powered (common wire), the
Minimum-Off Timer is also activated upon initial startup and
after power interruptions.
— If there is a call for cooling or heating during the MinimumOff Time, the thermostat displays “Wait.”
— When the Minimum Off Timer expires, “Cool On” or “Heat
On” (heat pumps only)” appears solidly in the display and
the compressor and fan turn on.
Temperature Sensor Operation and Checkout
Allow outdoor or indoor temperature sensor to absorb the air
for a minimum of five minutes before taking a reading. See the
Sensor instructions for more information.
NOTE: The C7189U, TR21 and TR21-A Temperature
Sensors are calibrated at the factory and cannot
be recalibrated in the field.
