Reason and Disposal
When the automatic mode is selected, the
air conditioner automatically selects the fan
speed.
When dry operation is selected, the air
conditioner automatically selects the fan
speed. The fan speed can be selected during
"COOL" and "FAN ONLY", and "HEAT"
Reason and Disposal
The remote control signal is not transmit-
ted, because the power supply is off.

The temperature cannot be
set during fan only operation.
Reason
The air conditioner operation stops since
the set time elapsed.
When the time set to start the air
conditioner is reached, the air conditioner
will automatically start and the appropriate
indicator will go off.

Direct the signal transmitter of the remote
control to the receiver of the indoor unit,
and then repeatedly push the ON/OFF
button twice.
Press Reset button.
