CAUTION
When selecting the “Remote controller setting”, if the detected temperature value between the temperature sensor of the indoor unit and the temperature sensor of the remote controller varies signi fi cantly, it is likely to return to the control status of temperature sensor of the indoor unit temporarily.
As the temperature sensor of remote controller detects the temperature near the wall, when there is a certain difference between the room temperature and the wall temperature, the sensor will not detect the room temperature correctly sometimes. Especially when the outer side of the wall on which the sensor is positioned is exposed to the open air, it is recommended to use the temperature sensor of the indoor unit to detect the room temperature when the indoor and outdoor temperature difference is signi fi cant.
The temperature sensor of the remote controller is not only used when there is a problem in the detection of the temperature sensor of the indoor unit.
