Judgment and measures

1.Check cables of remote controller and communication adapters.

•Handy remote controller LCD display OFF (Disconnection)

•Central remote controller [97] check code

1.Outdoor unit does not completely operate.

•Inter-unit cable check, correction of miscabling, case thermo operation

•Outdoor P.C. board check, P.C. board cables check

2.In normal operation

P.C. board (Indoor receiving/Outdoor sending) check

1.Check whether there is modification of remote controller connection (Group/ Individual) or not after power has been turned on (finish of group configuration/

address check).

*If group configuration and address are not normal when the power has been turned on, the mode automatically shifts to address setup mode. (Resetting of address)

1. Set the indoor capacity. (DN=I1)

1.Check outside devices.

2.Check indoor P.C. board.

1.Check thermal relay of fan motor.

2.Check indoor P.C. board.

1.Defect of drain pump

2.Clogging of drain pump

3.Check float switch.

4.Check indoor P.C. board.

1.Defective detection of position

2.Over-current protective circuit of indoor fan driving unit operates.

3.Lock of indoor fan

4.Check indoor P.C. board.

1.Check 4-way valve.

2.Check indoor heat exchanger (TC/TCJ) sensor.

3.Check indoor P.C. board.

1.Judge sub unit while master unit is in [E03], [L03], [L07], [L08].

2.Check indoor P.C. board.

1.Check indoor heat exchanger temperature sensor (TCJ).

2.Check indoor P.C. board.

1.Check indoor heat exchanger temperature sensor (TC).

2.Check indoor P.C. board.

1.Check indoor heat exchanger temperature sensor (TA).

2.Check indoor P.C. board.

1.Check indoor EEPROM. (including socket insertion)

2.Check indoor P.C. board.

1.Check cables of remote controller.

2.Check power cables of indoor unit.

3.Check indoor P.C. board.

1.Check cables of remote controller.

2.Check indoor power cable.

3.Check indoor P.C. board.
