During heating operation, if the pre heating/defrosting function is running, then the louver angle might not
be controllable or it cannot be moved on your own.
In cold winter when the temperature of the internal pipe of the cooling/heating machine is low, in order to
prevent lots of cold wind, the fan speed is set to low and the fan direction/speed is not controllable.
When the pre heating/defrosting LED is turned off, it will return to the previous state.
