8 Operation Details

8.1 .Cooling Mode Operation

When selecting the Cooling Mode Operation, the unit will operate according to the setting by the Remote Controller or the control panel on the indoor unit and the operation is as the following.

Time Delay Safety Control

3 min.----If the compressor stops, it will not restart within 3 minutes.(Protection of compressor).

7 Minutes Time Save Control

7 min.----The unit will automatically operate in 7 minutes even if the room temperature is not reached. (Prevention of raising the humidity)

Anti-Freezing Control

If temperature of evaporator is lower than 2 continuously

Evaporator Temperature

()

for 4 minutes, the compressor will cease to prevent the evaporator from freezing. Fan speed setting will not be changed. When temperature of evaporator reaches 10 ,compressor will restart.

During Cooling Mode Operation, the Time Delay Safety Control is available.

Time

Automatic Fan Speed Mode

During Cooling Mode Operation, use remote controller to select Automatic Fan Speed.

Fan speed will be at the point between "High speed" and "Medium speed".
