For some reason (Ex. The signal of the remote control does not reach the signal receiver of the indoor unit.), the
display of the remote control will not correspond with the actual ON/OFF status of the indoor unit:
The air conditioner is running but the cursor key which points to “OFF” appears. The air conditioner can be
1.
stopped with any button (Except for “ON/OFF”, “TIMER SET”, “TIMER ON”) pressed.
PRESS "OFF/ON" BUTTON
The air conditioner is on standby, but the cursor key which points to “OFF” disappears. The air conditioner can

1. When the switch is pressed between 0 to 5 seconds, Auto Mode operation starts to function.
2. When the switch is pressed between 5 to 8 seconds, the unit is forced to operate in Cooling Mode.
3. When the switch is pressed between 8 to 11 seconds, the unit is forced to operate in Heating Mode.
4. When the switch is pressed between 11 to 16 seconds and together with the signal from the remote controller,
the unit can be changed to different controlling setting .
5. When the switch is pressed between 16 to 21 seconds, either H14 error detection selection mode or remote
controller’s signal receiving sound can be cancelled or turned on.
6. If the intake air temperature is less than 16and the Forced Cooling is activated, because the prior operation
mode is heating, the compressor will stop for 3 minutes to start the Forced Cooling operation.
