7 minutes Time Save Control
Starting Current Control
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 Operation Details
8.1. Cooling Mode Operation
• 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.
• 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.

▲ T = Intake air temperature - Indoor heat exchanger temperature
This is to protect reverse rotation of the compressor when there is a instantaneous power failure.

Compressor Protection Control
Automatic Fan Speed Mode
• 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 stop totally.
• The above phenomenon is reset when there is a change to heating mode or stopped by Remote Control Switch.
• The above phenomenon is reset when there is a change to heating mode or stopped by Remote Control Switch.
When Automatic Fan Speed is selected at Remote Control during cooling operation.
• Fan speed rotates in the range of Hi to Me.
• Deodorizing Control.

Quiet Operation Control
(For Cooling Mode or cooling region of Soft Dry Mode)
• Purpose of this operation is to provide quite cooling operation compare to normal operation.
• When the Quiet Mode is set at the remote control, Quiet Mode LED illuminates, the sound level will be automatically decreased
• When the Quiet Mode is set at the remote control, Quiet Mode LED illuminates, the sound level will be automatically decreased
2 dB (Lo), decreased 3 dB (Hi, Me), against the present sound level operation.
• Quiet setting of fan speed rpm refer to Indoor Fan Speed Control.
• Dew formation become severe at Quiet Lo cool, therefore Quiet Lo cool is operated only 1h 30 min (1h QLo, 30 min QLo + 50).
• Dew formation become severe at Quiet Lo cool, therefore Quiet Lo cool is operated only 1h 30 min (1h QLo, 30 min QLo + 50).
After that, it goes back to Lo cool (However Quiet LED remains on).
• Manual Airflow Direction:-
− RPM control during Lo cool
− RPM control during Hi & Me cool
• Auto Airflow Direction:-
• Quiet Mode Operation will stop if:-
− Quiet mode button is pressed again.
− Stopped by ON/OFF switch.
− Timer OFF activates.
− Powerful mode button is pressed.
− When change mode to Air Circulation mode.
− Stopped by ON/OFF switch.
− Timer OFF activates.
− Powerful mode button is pressed.
− When change mode to Air Circulation mode.
