Failure code definition
Continuously disconnected for 60 seconds or
short circuit; failure alarm sounds.
When the CT current exceeds the specified
value for 5 consecutive seconds, failure alarm
sounds. The failure will be removed after 3
minutes. Failure is locked if it occurs thrice in
one hour.
The failure alarm will sound when it runs
below 20 rpm for 40 seconds or below 20%
of the target value for 2 minutes.
The failure will be removed after 3 minutes.
Failure is locked if it occurs thrice in one hour.
1.
Cooling: Ps=0.2MPa for 30 consecutive
minutes; failure alarm sounds. Ps > 0.3MPa
for 30 consecutive minutes; failure is
removed.

Inverter temp. ° C; failure is removed.
Failure is locked if it occurs thrice in one hour.
When the compressor current exceeds the
specified value for 5 consecutive seconds,
failure alarm sounds. The failure will be
removed after 3 minutes. Failure is locked if it
occurs thrice in one hour.
Model setting does not match the outdoor unit.
Module hardware over current. Failure is
locked if it occurs thrice in one hour.
Ins tantaneous over current of hardware at
the rectifier side of inverter module. Failure
is locked if it occurs thrice in one hour.
During s tart-up or operation, the rotor position
cannot be detected for 6 consecutive times;
failure alarm sounds. The inverter PCB will
recover automatically after compressor stops
for 5 seconds.
