Metal greatly reduces wireless signal strength, therefore it is not recommended to install the control module inside the air handler. If installing on a rooftop unit, use a plastic NEMA rated waterproof enclosure to mount the control module on the outside of the unit.

No, this model is not compatible with remote sensors.

If your thermostat was powered by batteries only (no AC power wire connection) then you can relocate it to another area of the dwelling as long as a good wireless connection is maintained. Before mounting the thermostat in a new location, test the wireless connection by switching the FAN setting between AUTO and ON a few times to verify a good wireless connection.

If PLEN SENS LOSS appears in the thermostat display that means the return air plenum sensor connected to the control module has not been installed or has lost connection. Check the wiring to the P1 and P2 terminals on the control module. You may need to contact a local service company.

When batteries become low a battery symbol will appear in the display. This usually occurs about 6 months before they become fully drained. If fully drained, the wireless signal is lost and the control module takes over providing factory default temperature control of 62 in heating and 85 in cooling.

There is no exact formula for how far away from the control module you can mount a wireless thermostat. Many factors, such as building construction, can affect a wireless signal. It is recommended to try pairing the thermostat in the desired location before mounting it. Metal walls can greatly reduce wireless range.

1) Put the thermostat into wireless connection mode by pressing and holding down the HOLD and RETURN buttons for 3 seconds.
2) The word CMOD will appear in the display with a flashing radio symbol.
3) On the Control Module, press and hold the CONNECT button for 3 seconds and release (The connect button is a small button located on the circuit board).
4) Once paired, the blue COMM indicator on the Control Module will turn on. Additionally, the radio symbol in the thermostat display will stop flashing.
5) Press RETURN to exit.

If a wireless remote humidity sensor was connected you can view the current humidity level by pressing the HUMID button. The indoor humidity level will display for a few seconds. If enabled, press the UP or DOWN arrow button to adjust the humidity setpoint.

If a wired or wireless outdoor remote sensor was connected, you can view the outdoor temperature by touching anywhere in the room temperature portion of the display screen. The outdoor temperature will display for a few seconds.

If a wireless remote sensor's battery becomes low, LOW BATT will appear in the thermostat display along with the sensor that has the low battery: ODS = Outdoor Sensor and IDS1, IDS2, IDS3 or IDS4 = Indoor Sensor #1, #2, #3 or #4. Change the batteries in the sensor as soon as possible. If the batteries in the thermostat become low, a battery symbol will appear in the thermostat display.

If wireless communication between the thermostat and a wireless remote sensor is lost a COMM LOSS message will appear in the thermostat display along with the device that has lost communication: ODS = Outdoor Sensor, HMS = Humidity Sensor and IDS1, IDS2, IDS3 or IDS4 = Indoor Sensor #1, #2, #3 or #4. Communication with this device should repair on it's own, but you can also try re-pairing the thermostat with the device by pressing the CONNECT button on the device for 3 seconds.

There is no exact formula for how far away from the thermostat you can mount a wireless remote sensor. Many factors, such as building construction, can affect a wireless signal. It is recommended to try pairing the remote sensor in the desired location before mounting it. Metal walls can greatly reduce wireless range.

1) Put the thermostat into wireless connection mode by pressing and holding down the CONFIG and DAY/TIME buttons for 3 seconds.
2) Press NEXT until the word SENS appears in the display.
3) On the sensor you wish to pair, press and hold the CONNECT button for 3 seconds (The connect button is a small button located on the back of the indoor sensor or on the circuit board of the outdoor and humidity sensors).
4) Once paired, the blue LED on the sensor will turn on for 60 seconds. Additionally, the thermostat display will indicate which sensor has been paired (i.e. ODS for Outdoor Sensor).
5) Press NEXT on the thermostat and repeat steps 3 and 4 or press RETURN to exit.

A maximum of four BlueLink wireless remote sensors can be connected. Out of this maximum, only one wireless outdoor sensor or wireless humidity sensor can be connected.
