the remote controller varies signicantly, 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 signicant.
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.
