malfunction
The inter-chip
communication failure
on the main control
board
Remarks:
1. In heating mode, if the water out temperature is higher than the set temperature over 7℃, LED
controller displays EE04 for water over-heating protection.
For example as below:

mode
1. Voltage signal abnormal
EE22 2. Driver board is damaged
3. Main board failure
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 just connected to
EE25
one phase or two phases.
1. Wrong EEPROM data in the program or
EE27 failed input of EEPROM data
2. Main board failure
EE28 Main board failure

1. Change a new main board
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
3. Check the compressor or change a
new one
Change driver board or main board
Check the actual wiring according to the
circuit diagram
1. Re-enter correct EEPROM data
2. Change a new main board
1. Stop electricity supply and restart it
2. Change a new main board
