General Functions
Pre-heat Operation
When the equipment has stopped and t
[outside]
< 4˚C, the compressor is warmed-up by passing a single-
phase (U, V phase) current through the compressor motor to speed up the start. The power consumption is
50~60W.
Hot Start Function
During defrosting or when the thermostat is on in heating mode, if the indoor heat exchanger temperature
is < 29˚C, restrict the fan rotating speed to L tap and under to prevent the cold draft.
Dry Mode
The dry mode removes humidity while maintaining the room temperature. The temperature and fan cannot
be regulated during dry mode.
