18 F11
Compressor out of step From the module board
19 F28
Position detection ioop fault
From the module board,Appear 3 times in 10 minutes
21 E9 Indoor overload shutdown
Compressor start up 2 minutes after the start of testing.If Tc≥
63°C
last on 5 minutes the compressor stop.When the
compressorstops for
more than 5 minutes and Tc < 39°C the compressor resumes
21 E5 Indoor anti-frost stop
Compressor start up 2 minutes after the start of testing.If Tc≤
1°C
last on 2 minutes the compressor stop.When the
compressorstops for
more than 3 minutes and Tc > 9°Cthe compressor resumes.
23 F5
Module temperature is
too high(95 °C)
Module temperature is too high for protection.
24 F2
Compressor software
over current
From themodule board.1.35 times the total current.
25 F23
Phase current over current
If the phase current of the compressor is greater than
the phase current stop value in EE of the outdoor unit
during runing,then compressor stop.
After 3 minutes compressor restart.
27 F24 CT of bolt
When the total current of the compressor is detected to be
less than0.5A and the compressor frequency is greater than
50Hz, theduration is one minute.
Then force the compressor to stop for 3 minutes,no
fault confirmed
37 F34
Outdoor condenser temp.
too high protection
Error lock if it occurs 3 times in 30 minutes
38 F35
Module unknown fault
43 F41
High pressure protection System high pressure protection
45 F42
Low pressure protection System low pressure protection
46 F43 Type matching exception Indoor unit and outdoor unit do not match
