When the outdoor heat exchanger temperature is lower than 0°C and the all operation mode has been
stopped for 30 minutes, power is applied to the compressor and the compressor is heated.
(By heating the compressor, warm air is quickly discharged when operation is started.)
When operation was started and when the outdoor heat exchanger temperature rises to 2°C or greater,
preheating is ended.
