7
Send from the module,3 times within 30 minutes send to indoor board
F4
Discharging temp.senor
Td abnormal
8
After the press is started for10 minnutes,the Td temp.exceed the
temp. in EE.3 times within 30 minutes send to indoor board.
F8

F7
11
Start up and test immediately
F6
12
F25
13
F30
The press suction tpmp.
is too high
14
After starting up 10 minnutes to test, for 5 minutes,the Ts temp.
was detected to be over
40℃，
then shut down compressor send to indoor
board.
●
Starting again in three minutes.
E7
Communication fault
15
Communication failure between indoor unit and outdoor unit
F13
Lack of refrigerant
16
The comressor runs continuously for more than 5 minutes and the
current value of outdoor unit is 0.6A-1.6A.Meet the cool/heat
●
conditions,flashing outdoor lights
F14
Four-way valve fault
17
Check the indoor unit coil temp.,after the heating compressor starts
up 10minutes,Tc≤
0℃
last on one minute,then stop the compressor.
Deforsting and deforsting exit will not be detected within 5 minutes
F11
Compressor out of step
18
From the module board
F28
Position detection
ioop fault
19
From the module board,Appear 3 times in 10 minutes and confirm
E9
Indoor overload shutdown
21
Compressor start up 2 minutes after the start of testing.If Tc≤
1℃
last on 2 minutes the compressor stop.When the compressorstops for
more than 3 minutes and Tc
＞9℃，
the compressor resumes.
E5
Indoor anti-frost stop
21
F5
Module temperature is
too high(95?)
23
Module temperature is too high for protection.
F2
Compressor software
over current
24
From themodule board.1.35 times the total current.
F23
Phase current over current
25
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.
F24
CT of bolt
27
，
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
