Error code
1.Compressor runs out of step
2. Wrong program
EE21
3. Impurity inside compressor causes
the unstable rotate speed
1. Voltage signal abnormal
EE22
2. Driver board is damaged
1. Main board is damaged
2. Compressor wiring error or poor
contact or unconnected
EE23
3. Liquid accumulation inside
4. Wrong phase connection for
compressor
EE24 Ambient Temperature device failure
Compressors U, V, W are connected
EE25
to one phase or two phases.
1. Four-way valve reversal failure
EE26 2. Lack of refrigerant (no detect when
T3 or T5 malfunction)
1. Wrong EEPROM data in the
program or failed input of EEPROM

Reason Solution
1. Check the main board or
change a new one
2. Enter correct program
1. Check the main board or
change a new one
2. Change a new driver
board
1. Check the main board or
change a new one
2. Check the compressor
wiring according to the
circuit diagram
Check the compressor or
change a new one
Change driver board or
main board
Check the actual wiring
according to the circuit
diagram
1. Switch to Cooling mode
to check the 4-way valve if
it has been reversed
correctly
2. Change a new 4-way
valve
3. Fill with gas
1. Re-enter correct
EEPROM data
2. Change a new main
board
1. Turn off electricity
supply and restart it
2. Change a new main
board
