Contents of Malfunction Diagnosis and Analysis
1 F12 EEPROM ERROR EEPROM chip damaged or data fault
2 F1 IPM protection Input over current occured been detected by PIM hardware
3 F22 AC overcurrent protection
The AC current value exceeds the total current stop value
in EE.Error lock if appear 3 times within 30 minutes.
4 F3 Communication fault Communication failure between outdoor board and module
5 F20 Press overload Send from the module.
6 F19
Overvoltage or underv-
oltage protection
The voltage of P/N exceed or below the EE voltage limmit of
the module board.
7 F27 Press blovked/stoped
Send from the module,3 times within 30 minutes send to indoor
board
8 F4
Discharging temp.senor Td
abnormal
After the press is started for10 minnutes,the Td temp.exceed the
temp. in EE.3 times within 30 minutes send to indoor board.
9 F8 DC fan motor fault
Error status confirm and lock if occurs 3 times within
30 minutes
10 F21 Te resistance fault Start up and test immediately
11 F7 Ts resistance fault Start up and test immediately
12 F6 Ta resistance fault Start up and test immediately
13 F25 Td resistance fault
After starting up 10 minnutes to test, 3 times within 30 minutes
send to indoor board.
14 F30
The press suction tpmp.is
too high
After starting up 10 minnutes to test, for 5 minutes,the Ts temp.
was detected to be over 40°C then shut down compressor send
to indoor board. Starting again in three minutes.
15 E7 Communication fault Communication failure between indoor unit and outdoor unit
16 F13 Lack of refrigerant
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.
17 F14 Four-way valve fault
Check the indoor unit coil temp.,after the heating compressor
starts up 10minutes,Tc≤0°C last on one minute,then stop the
compressor.
Deforsting and deforsting exit will not be detected within
5 minutes
