8 Operation Details
8.1. Cooling Mode Operation
•
When the compressor is stopped by Remote Control, it restarts after 3 minutes when it is turned ON by Remote Control.
•
When the setting temperature is reached during cooling operation, the compressor stops and it will not start for 3 minutes.
•
The compressor will start automatically if it has stopped for 7 minutes even if the room temperature is between the compressor
ON temperature and OFF temperature.
ON temperature and OFF temperature.
•
When the compressor, outdoor fan motor & indoor fan motor are simultaneously started, the indoor fan motor will operate 1.6
second later.

•
If the compressor is operating continuously for 5 minutes or longer and the temperature difference between intake air and
indoor heat exchanger is 2.5°C or less for 2 minutes, compressor will stop and restart automatically.
