16.5.13 Indoor/Outdoor Abnormal Communication (H90)

Malfunction Decision Conditions:

During operation of heating, the data received from outdoor unit in indoor unit signal transmission is checked
whether it is normal.

Malfunction Caused:

1  Faulty outdoor unit PCB (main).
2  Faulty indoor unit PCB (main).
3  Indoor-outdoor signal transmission error due to wrong wiring.
4  Indoor-outdoor signal transmission error due to breaking of wire in the connection wires between the indoor

and outdoor units.

5 Indoor-outdoor signal transmission error due to disturbed power supply waveform.

Abnormality Judgment:

Continue for 1 minute after operation.
