No, this model is not compatible with remote sensors.

Wi-Fi will work without a common “C” wire on most conventional systems. Heat pump systems and heat-only/cool-only systems do require a common “C” wire in order to operate Wi-Fi.

If you change your Wi-Fi router password, you will also need to clear the Wi-Fi settings in the thermostat and then update those Wi-Fi settings in the app. Open the app and go to the “Select Thermostat” screen. Select UPDATE ACCOUNT and enter you app account password. Select WI-FI SETTINGS. Select the thermostat to update and press SELECT. Select WI-FI NETWORK and press ENTER. Enter your new network name and password and then press ENTER. Follow the instructions in the app. For complete instructions, open a copy of the Wi-Fi Setup Guide by clicking here: Wi-Fi Setup Guide

If you change your Wi-Fi router password, you will also need to clear the Wi-Fi connection in the thermostat and then update your Wi-Fi settings in the app. Open the app and go to the “Select Thermostat” screen. Select UPDATE ACCOUNT and enter you app account password. Select WI-FI SETTINGS. Select the thermostat to update and press SELECT. Select WI-FI PASSWORD and press ENTER. Enter your new password and press ENTER. Follow the instructions in the app. For complete instructions, open a copy of the Wi-Fi Setup Guide by clicking here: Wi-Fi Setup Guide

Once you have the new Wi-Fi router up and running you will have to clear the Wi-Fi connection in the thermostat and then change the Wi-Fi settings in the app. For complete instructions, open a copy of the Wi-Fi Setup Guide by clicking here: Wi-Fi Setup Guide.

1) Press and hold down the CONFIG button for one second.
2) Press NEXT until you see the word WIFI in the display.
3) Press the ▲ (up) button until CL WIFI appears in the display.
4) Press NEXT to exit and clear the Wi-Fi connection.

BlueLink thermostats are compatible with 802.11G networks. Ensure your router is either set up for G or MIXED mode. MIXED mode will accept most modes of communication.

Yes, but you must unhide the SSID during the thermostat registration process. Once registration is complete, you can once again hide the SSID using your routers network configuration tools.

Yes, however you must connect to the 2.4 GHz band and not the 5 GHz band. Additionally, these two bands must have different network names and network passwords. If you are using the same name and/or password for both bands you may experience connection problems with your thermostat.

No, your BlueLink Smart Connect thermostat is not able to connect to a Wi-Fi hotspot at this time.

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.

If the in the thermostat display is flashing it means your thermostat has lost it’s Wi-Fi connection. Check your router to make sure you have Internet access. You may also try removing the thermostat from the wall sub-base for 15 seconds to reset the connection.

Most standard router security protocols are supported: OPEN, WPA/TKIP/PSK, WPA2/AES/PSK, WPA2/MIXED/PSK, WPA/AES/PSK and WPA2/TKIP/PSK.

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.

Press and hold down the CONFIG and DAY/TIME buttons for 3 seconds and the thermostat will display the network name (SSID) you are connected to. If you are not connected to a network, the display will flash WIFI and SKIP. Press RETURN to exit.

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.

This thermostat can only be used on a millivolt system if Wi-Fi is not being used and the thermostat is powered by batteries only.

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.
