When the unit is running with follow me function, if the PCB doesn’t receive any signal from remote controller for 7 minutes or pressing FOLLOW ME button again, the follow me function will be turned off automatically, and the
temperature collection function of room temperature sensor will be available, the PCB will control the unit according to the room temperature detected from its own room temperature sensor and setting temperature.
8.18 Outdoor heating cable (Optional)
A heating cable can be fixed on outdoor chassis to help deicing and to avoid freezing. Another heating cable can be fixed around compressor to help starting the compressor. These heating cables are useful to improve the performance of the air conditioner especially when the outdoor ambient temperature is very low. The rated power voltage for the heating cables is 220V‐240V. The action of the heating cables is controlled by the PCB. If outdoor temperature is lower than 5
℃, the heating cable will begin to work. If outdoor temperature is higher than 15℃, the heating cable will stop working.
