INDOOR UNIT Error Method:

Indicate or Display:

Detective Actuators:

Detective details:

Forecast of Cause :

Manual auto switch error

Indoor unit Controller PCB

Indicator PCB

Manual auto switch

When the Manual Auto Switch becomes ON for consecutive 60 or

more seconds.

1. Manual auto switch failure 2.Controller PCB and Indicator PCB failure

Check Point 1 : Check the Manual auto switch

Check if Manual auto switch is kept pressed.

Check Point 2 : Replace Controller PCB

If Check Point 1 do not improve the symptom, change Controller PCB and Indicator PCB.

Check ON/OFF switching operation by using a meter.

>>If Manual Auto Switch is disabled (on/off switching), replace it.

Outdoor Unit : No indication

Indoor Unit : Operation lamp: 3 times Flash, Timer lamp: 5 times Flash

Economy lamp: Continuous flash.
