LED INDICATION & SELF-DIAGNOSIS FUNCTION
1 When the unit is switched on, the green LBD is on. When the unit is off, the green LBD is off
2 When in need of removing cold air flow and de-frosting under heating operation mode. The green LED will flash
on and off (on for 1.5seconds.off for half second)
3 Under any operation mode. When there is something wrong with the indoor temperature sensor & coil
temperature sensor, the failure can be indicate by yellow & green light as showed in below form.

FAILURE IN OUTDOOR UNIT,WHEN COOLING:
5 minutes after the close of the compressor relay, If the indoor coil temperature keeps higher than 25
℃
for 20 minutes
running, Meanwhile the timing lamp flashes on and off as showed above, it indicates that the outdoor unit is abnormal. If
indoor coil temperature keeps higher 25
℃
for 40 minutes running, the compressor, outdoor fan motor will stop running. Yet
the indoor fan motor will still keep operation as normal, indication lamp keeps original status, and the green lamp will be on,
yellow lamp will flash. During the above-mentioned process, if the compressor relay has ever been off, then the time has to be
counted from the moment the compressor relay closes again.

If the coil temperature keeps lower than 30
℃
, when the compressor has worked for 20 minutes running, And
indoor fan motor keeps low speed, this indicates that the outdoor unit is abnormal . In this case, the outdoor unit will stop
running, Green lamp is on, while yellow lamp flashes.
4 If there is failure in indoor temperature sensor& coil temperature sensor, then the indoor unit will
stop working, and the indication lamps indicate the failure as showed in the above form.
