z Outdoor failure display
There is a LED on outdoor power board, when compressor is running; it is normally light;
when no feedback of signal to power board from compressor, it will wink by lighting 1s and
going out 1s. If failures happened, it will light 0.5s, go out 0.5s, winking several times and go
out 3s for a cycle to indicate failures. The failure list is the follow:
Wink time Failure
1
IPM protection

4
Discharge temperature too high
5
