8 Operation Details

8.1.

COOLING MODE OPERATION

Cooling in operation according to the remote control setting.
8.1.1. Time Delay Safety Control (3 minutes)
· When the compressor is stopped by Power Switch, Remote Control or when there is a power failure, it restarts after 3 minutes
when the Power Switch, Remote Control is turned ON or when 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.
8.1.2. 7 Minutes Time Save Control
· The compressor will start automatically if it has stopped for 7 minutes even if the room temperature is below the compressor
ON temperature.
8.1.3. 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.
8.1.4. Compressor Protection Control
· After the compressor operates 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 3 times, the compressor will stop.
· The above phenomenon is reset when there is a change to heating mode or stopped by Remote Control Switch.
8.1.5. 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, the compressor will stop and restart automatically.
(Time Delay Safety Control is valid).
T =Intake air temperature - Indoor heat exchanger temperature
This is to protect the compressor against reverse rotation when there is an instantaneous power failure.
