Anti-Freezing Control
•
•
•
• If the temperature of the indoor heat exchanger falls
continuously below 2°C for 4 minutes or more, the
compressor turns off to protect the indoor heat exchanger
from freezing. The fan speed setting remains the same.

Compressor Reverse Rotation Protection Control
8.2. 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.
