While in forced operation, the key input by the remote control has no effect and the buzzer sounds 10 times to indicate the forced operation.

Test operation

During the TEST OPERATION, the unit operates in cooling mode at high speed fan, regardless of room temperature and resets in 18±1 minutes.

During test operation, if remote controller signal is received, the unit operates as remote controller sets.

If you want to use this operation, open the front panel upward and Press the power button let it be pressed for about 3 seconds.

If you want to stop the operation, re-press the button.

Auto restart

In case the power comes on again after a power failure, Auto Restarting Operation is the function to operate procedures automatically to the previous operating conditions.

Protection of the evaporator pipe from frosting

If the indoor pipe temp is below 0°C in 7 min. after the compressor operates without any pause while in cooling cycle operation mode, the compressor and the outdoor fan are turned off in order to protect the indoor evaporator pipe from frosting.

When the indoor pipe temp is 7°C or higher after 3 min. pause of the compressor, the compressor and the outdoor fan is turned on according to the condition of the room temperature.

Buzzer Sounding operation

When the appliance-operation key is input by the remote control, the short "beep-beep-" sounds.

When the appliance-pause key is input by the remote control, the long "beep— " sounds.
