1) Cooling Mode Operation
Cooling in operation according to Remote Control setting.
• When the compressor is stopped by Power Switch, Remote Control or there is a power failure, it restarts after 3
minutes when the Power Switch, Remote Control is turned ON or the power supply is resumed.
• 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 below the
compressor ON temperature.
• After the compressor starts for 50 seconds but the outdoor fan motor is still OFF, the compressor will stop and
restart automatically. (Time Delay Safety Control is valid).
• If the above phenomenon is repeated for 3 times, the compressor will stops.
• The above phenomenon is reset when there is a change to heating mode or stopped by Remote Control Switch.
• If the compressor is operating continually 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).
∆
T = intake air temperature – indoor heat exchanger temperature
This is to protect reverse rotation of the compressor when there is a instantaneous power failure.
• If the temperature of the indoor heat exchanger
falls continously below 2
°
C for 4 minutes, the
compressor turns off to protect the indoor heat
exchanger from freezing. The fan speed setting
remains the same.
• Compressor recommences when the indoor heat
exchanger temperature rises to 10
°
C (Recovery).
