Operation Details

1) Cooling Mode Operation
Cooling in operation according to Remote Control setting.
Time Delay Safety Control (3 minutes)
• 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.
7 minutes Time Saved Control
• The compressor will start automatically if it has stopped for 7 minutes even if the room temperature is below the
compressor ON temperature.
Anti-Freezing Control
• 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).
* 3 minutes waiting of Time Delay Safety
Control is valid for Cooling Operation.
Compressor Reverse Rotation
Protection Control
• 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).
• Compressor starts for
• ∆ T
2.5˚C for 2 minutes
∆ T = Intake air temperature – Indoor heat exchanger temperature
This is to protect reverse rotation of the compressor when there is a instantaneous power failure.
