8 Operation Details

8.1.

Cooling Mode Operation

Cooling in operation according to Remote Control setting.
Time Delay Safety Control (3 minutes)
• 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.
7 minutes Time Save Control
• 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.
Starting Current Control
• When the compressor, outdoor fan motor & indoor fan motor are simultaneously started, the indoor fan motor will operate 1.6
second later.
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 will restart again when the indoor heat
exchanger temperature rises to 10°C (Recovery).
3 minutes waiting of Time Delay Safety Control is valid for
Cooling Operation.
Compressor Reverse Rotation Protection Control
• 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.
(Time Delay Safety Control is valid)
s T = Intake air temperature - Indoor heat exchanger temperature
This is to protect reverse rotation of the compressor when there is a instantaneous power failure.
