Tliqsc temp. sensor
failure
Continuous disconnect for 60 seconds or
short circuit, failure alarm.
Resumable
64 CT value too high
When the CT current exceeds the specied
value for 5 consecutive seconds, failure
alarm. The failure will be removed after 3
minutes. Failure is locked if it occurs 3 times
in one hour.
Once failure
locked, un-
resumable.
71-0 DC Fan1 failure
The failure will alarm 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 3 times in one
hour.
Once failure
locked, un-
resumable.
71-1 DC Fan2 failure
78 Lack of refrigerant
1.Cooling: Ps≤0.2MPa for 30 consecutive
minutes, failure alarm. Ps≥0.3MPa for 30
consecutive minutes, failure removed.
2.Heating:Both LEVa equals to 470pls and
Ts-Ps≥20

Compressor current
protection
When the compressor current exceeds the
specied value for 5 consecutive seconds,
failure alarm. The failure will be removed
after 3 minutes. Failure is locked if it occurs 3
times in one hour.
