8 Operation Details (CS-PC9CKH & CS-PC12CKH)
8.1. Cooling Mode Operation
•
•
•
• When the compressor is stopped by Remote Control, it restarts after 3 minutes when the Remote Control is turned ON.
•
•
•
• 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.
•
•
•
• When the compressor outdoor fan motor and 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.
