check open or short circuit.
- Replace the main PCB or heat pump.
E1
Main PCB error
- Replace the main PCB.
E2
L7
Control PCB error
- Replace the
control
PCB.
F5
Communication error between
main PCB to control PCB
- Check the
communication
connector on the
main PCB and control PCB.
- Replace the main PCB or control PCB.
E8 High inlet current error
- Check the installation location.

H8 Current error - Replace the main PCB.
L4 High temperature of module error
- Check the installation location.
- Remove foreign objects from the evaporator
coil (e.g. fallen leaves, grass, snow)
- Check the Fan motor is not flowing by dirt.
- Replace the main PCB or fan motor.
L5 High outlet current error
- Measure resistance of the discharged
thermistor.
- Measure resistance of coil of expansion vale to
check open or short circuit.
- Replace the main PCB or heat pump.
P4 Module temperature thermistor error - Replace the main PCB.
U2 High voltage error - Check the supply voltage.
HJ Water circuit error
- Check the inlet water valve.
- Check for any piping bend, blocking, kink or
frozen.
- Measure resistance of each Thermistor.
- Measure resistance of coil of expansion vale to
check open or short circuit.
- Replace the main PCB or heat pump.
EC High water outlet error
- Check the water circuit is not flowing by air, dirt
or scaling.
- If the water circulation pump is not working,
replace the pump.
