— Users cannot make changes to the temperature setpoint or 

any schedule, system, or fan settings.

— The only features available are HOLIDAY and OVERRIDE. 

— To unlock the screen, see Advanced Settings section. 

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 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.

The thermostat provides an alert that the heating or cooling 

system is coming on before a scheduled time by displaying 

“Recovery” on the screen.

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 Minimum-

Off 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.

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.

When installed with Thermostat ISU 0340 set to 3, the remote 

inside temperature is displayed on the Thermostat Home 

Screen as Inside Temperature. The thermostat internal 

temperature sensor is not used.

The C7189U can be used to provide one remote sensor input 

or as a temperature averaging network with multiple TR21 

Sensors connected, as shown in Fig. 28.

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.

When installed with Thermostat ISU 0340 set to 3 or 4, the 

remote inside temperature is displayed on the Thermostat 

Home Screen as Inside Temperature. The thermostat internal 

temperature sensor is not used.

The TR21 can be used to provide one remote sensor input or 

as a temperature averaging network with multiple TR21 

Sensors connected, as shown in Fig. 25 through 27.

For best results, allow TR21 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 the 

wiring terminals. Use an ohmmeter to measure the resistance 

across the sensor. Then verify the sensor accuracy with the 

temperature/resistance in Fig. 41.
