The thermostat acquires the room temperature using the built-in sensor and/or the external room temperature sensor, and maintains the setpoint by delivering control commands to heating and/or cooling equipment. If no external room temperature sensor is connected or if the input value of the external sensor is invalid, only the built-in sensor is used to provide values for the thermostat. If the external sensor is connected and can provide valid values with the built-in sensor, the thermostat displays the average value of the built-in and external sensors.
On the home screen, the current room temperature is displayed and the temperature setpoint can be changed as desired. The units can be selected between °C and °F (the default unit).
After the initial setup of the thermostat, the displayed room temperature may not be correct because the temperature sensors need time for the calibration. Wait for at least one hour for the calibration.
Adjust the temperature setpoint on the home screen
- From the Home screen, drag the temperature slider to the right to increase the temperature setpoint, or to the left to decrease the temperature setpoint.
Change the temperature unit
- From the Home screen, tap , and then tap .
- Tap and then tap to change from Fahrenheit to Celsius, or tap to change from Celsius to Fahrenheit.
