Test 2 : Check Wired Remote Controller and Controller PCB
Test 1 : Check the connection of terminal
1. Connection failure 2. Wired Remote Controller failure 3. Controller PCB failure
Check & correct the followings.
Check the connection of terminal between Wired Remote Controller and indoor unit,
and check if there is a disconnection of the cable.
>> If it is DC12V, Remote Control is failure. (Controller PCB is normal) >> Replace Remote Control
>> If it is DC 0V, Controller PCB is failure. (Check Remote Control once again) >> Replace Controller PCB
Check Voltage at terminal 1-3 of Controller PCB or Communication PCB.
