The display panel id indoor unit contains the following function indicators :
1 MANUAL Button
* This button is used to operate the unit temporarily in case you misplace
the remote control or its batteries are exhausted.
* Once you push temporary button, the air conditioner will run in such order :
Auto, Forced cool, off and back to Auto
AUTO
The OPERATION lamp is lit, and the air conditioner will run under AUTO mode.
The remote controller operation is enabled to operate according to the received signal.
FORCED COOL
The OPERATION lamp flashes, the air conditioner will turn to AUTO after it is enforced to cool
with a wind speed of HIGH for 30 minutes. The remote controller operation is disabled.
OFF
The OPERATION lamp goes off. The air conditioner is OFF while the remote controller operation
is enabled.
2 OPERATION green led
* OPERATION green led lights on when the air conditioner operates
* OPERATION green led lights off when the air conditioner stops
3 TIMER green led
* TIMER green led lights on when timer function operates
* TIMER green led lights off when timer function stops
4 DEF. / FAN red led
* This led lights on when defrost protection is activated and lights off
when defrost protection terminates in heat mode.
5 ALARM red led
ALARM red led flashes when there is a malfunction in outdoor unit
6 Infrared Signal Receiver
( In case of using remote control )
7 Display Digital Tube
* This display shows error code in case of a malfunction.

NOTES
1- Prior to the malfunction repair,disconnect the electrical mains supply by moving the circuit breaker to OFF position.
2- After repairing the malfunction, connect the electrical main supply by moving the circuit breaker to ON position
and operate the air conditioner by using the wireless remote control or using wired room controller.
