							8 Operation Details
8.1. Indoor Fan Speed Control
 
    • 
• •  • 
Auto Fan Speed Control
When set toAuto Fan Speed, the fan speed is adjusted between maximum and minimum setting as shown in the table.
 
    • 
• •  • 
Manual Fan Speed Control
Basic fan speed adjustment (3 settings, from Lo to Hi) can be carried out by using the Fan Speed selection button at the remote
control.

							Coolin g in operation according to Remote Control setting.
Time DelaySafety Control (3 minutes)
7 minutes TimeSave Control
Starting Current Control
Anti-Freezing Control
 
    • 
• •  • 
If the temperature of the indoor heat exchan ger falls
continuously below 2°C for 4 minutes or more, the
compressor turns off to protect the indoor heat exchan ger
from freezing. The fan speed setting remains the same.
 
    • 
• •  • 
Compressor will restart again when the indoor heat
exchan ger temperature rises to 10°C (Recovery).
3 minutes waiting of Time Delay Safety Control is valid for
Cooling Operation.
Compressor Reverse Rotation Protection Control
8.2. Cooling Mode Operation
 
    • 
• •  • 
W hen the compressor is stopped by Remote Control, it restarts after 3 minutes when the Remote Control is turned ON.
 
    • 
• •  • 
W hen 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.
 
    • 
• •  • 
W hen the compressor outdoor fan motor and indoor fan motor are simultaneousl y started, the indoor fan motor will operate 1.6
second later.
 
    • 
• •  • 
If the compressor is operating continuously for 5 minutes or longer and thetemperature difference between intake air and
indoor heat exchan ger 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.

							Quiet Operation Control
(For Coolin g Mode or cooling region of Soft Dry Mode)
 
    • 
• •  • 
Purpose of this operation is to provide quite cooling operation compare to normal operation.
 
    • 
• •  • 
W hen 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).
After that, it goes back to Lo cool (However Quiet LED remains on).

    • 
• •  • 
Quiet Mode Operation will stop if:-
 
    − 
− −  − 
Quiet mode button is pressed again.
 
    − 
− −  − 
Stopped by ON/OFF switch.
 
    − 
− −  − 
Timer OFF activates.
 
    − 
− −  − 
W hen change mode to Air Circulation mode.

8.3. Soft Dry Mode Operation
 
    • 
• •  • 
The unit starts cooling operation until the room temperature reaches the setting temperature set on the Remote Control, and
then Soft Dry operation will start.
 
    • 
• •  • 
During Soft Dry operation, the Indoor Fan will operate at Lo- speed.
 
    • 
• •  • 
The operation will be switched on and off for up to 10 minutes “ON” and 6 minutes “OFF”. Once Soft Dry operation is turned
off, it stops for 6 minutes.
 
    • 
• •  • 
Once the compressor stops, it will not start for 3 minutes during Cooling operation.
 
    • 
• •  • 
Same as Starting Current Control for Coolin g Mode operation.
 
    • 
• •  • 
Same as Anti-Freezing Control for Coolin g Mode operation. (For Soft Dry region, 6 minutes waiting is valid during compressor
stops.)
 
    • 
• •  • 
Same as Compressor Reverse Rotation Protection Control for Coolin g Mode Operation. (For Soft Dry region, 6 minutes waiting
is valid during compressor stops.)
When Automatic Fan Speed is selected at Remote Control during Soft Dry operation.
 
    • 
• •  • 
Fan speed off and on at Lo- speed.
 
    • 
• •  •
