4 Replacing a Thermostat or a Sensor
Replacing a Thermostat – If you are replacing a thermostat that is paired with an
existing wireless sensor, you will need to clear the remote sensor and pair it again
with the newly installed thermostat.
1. Install the new thermostat.
2. On the wireless remote sensor you want to clear, press and hold the CONNECT
button for 10 seconds (see Figure 1) until the red LED turns on solid.
3. Release the CONNECT button and the blue and red LED will each flash once to
indicate the sensor was successfully cleared.
4. Pair the sensor again.
Replacing a Sensor – If you are replacing a wireless remote sensor that is paired
with an existing thermostat, you will need to clear the thermostat’s remote sensor
settings before pairing the new wireless remote sensor.
1. Install the new wireless remote sensor.
2. Thermostat remote sensor settings are cleared in the Installer Settings. Refer to
the Installer Settings section of the thermostat Installer Guide.
3. Once the remote sensor settings are cleared you will need to pair your new
wireless remote sensor. You will also need to pair any other existing wireless
remote sensors that were previously connected.

5 Communication Loss and Low Battery
Communication Loss – If communication between the remote sensor and ther-
mostat is lost, the red LED on the remote sensor will begin to flash once every 10
seconds. The thermostat display will also indicate which wireless remote sensor
has lost communication. The sensor will attempt to reconnect to the thermostat
several times automatically.
NOTE: To reconnect manually, press and hold the CONNECT button for 3 seconds.
Remote Sensor Low Battery – If the batteries in a wireless remote sensor are low,
the red LED will flash 3 times every 30 seconds. The thermostat display will also
indicate which wireless remote sensor has a low battery. Replace the remote sensor
batteries as soon as possible. Be sure to maintain battery “+” and “-” polarity
. Use
only 2 “AA” lithium batteries to maintain operation in most weather conditions.
