Description for self-diagnosis = Power failure (When power is ON)

Item = B
Check code = 00
Block display = OPERATION (Green) Flashing display (5 Hz)
Description for self-diagnosis = Protective circuit operation for indoor P.C board

Item = C
Check code = 01
Block display = OPERATION (green) TIMER (Yellow) Flashing display (5 Hz)
Description for self-diagnosis = Protective circuit operation for connecting cable and signal system.

Item = D
Check code = 02
Block display = Operation (green) filter (orange)
Description for self-diagnosis = Protective circuit operation for outdoor P.C board

Item = E
Check code = 03
Block display = OPERATION (green) TIMER (Yellow) Flashing display (5 Hz)

Caution at Servicing
1. After servicing, press the START/STOP button to return to the normal mode.
2. After servicing by the check code, turn off breaker of the supply and turn on breaker of the power supply again so that memory in the microcomputer returns the initial status.
however, the check codes are not deleted even if the power supply is turned off because they are stored in the fixed memory.
3 After servicing, press (CLR) button under check mode status and then send the check code "7F" to the indoor unit.
The error code stored in memory is cleared.
