1. Click the '+' button at the top right of the interface in 'Menu' -> 'Sensors'
on the thermostat and tap 'Next'. Sensors Pair Please press and hold the button on the back of the sensor for 3 seconds, the indicator will ash red, then tap Next. Next 2. Remove the rear cover of the sensor. 3. Press and hold the button on the back of the sensor for 3 seconds until the indicator on the front of the sensor flash red. 4. Wait for sensors to pair automatically. When the pairing is successful, the sensor flashes green light for 3 times. Now you can set the participation period of the sensor. During this period, the thermostat will calculate the average temperature of all the sensors in the occupied state as a reference and use it as the indoor temperature on the main screen. Sensors 513 29.8/Occupied My Sensor 24.9/Occupied Tip: When you change the setting of sensor, the indoor temperature on the main screen need update in 2 minutes. If there is no one in the room where the sensor is located, that sensor will not participate in that calculation. 42 used. again. used. 2. Wi-Fi configuration of the thermostat failed
