MALFUNCTIONING

7.
When an error occurs or the protection mode is set automatically, the circuit board and
the wired controller will both display the error message.
Error Meaning
2. No water flow
Water Flow 2. Flow switch failure
P01
failure 3. Water system block
1.Water flow is too small
2. High-pressure switch
High pressure is damaged；
P02
protection 3.Refrigerant system
block；
4. EEV dead lock.
1. Lack of gas
2.Refrigerant system
Low pressure
P03 block；
protection
3.Exceed heat pump
operation range
1. Heat Pump fan
T3 Coil
2. Evaporator is
P04 overheat
protection
3. T3 coil sensor
Exhausting gas 1. Lack of gas
P05 temperature 2. sensor position was
protection
Analysis
1. Check if water in valve is
closed or no water in
2.Check if flow switch is
blocked or damaged
3. Check if"Y"Shape filter
blocked
1. Check if water flow is not
enough or water pump flow is
not enough;
2. Check if high-pressure
switch is off；
3.Check if refrigerant system is
blocked
4. When heat pump is off and
turn the heat pump on and off
to check if EEV can be listened
by sound of reset.
1.Check if gas system is leaking
2. Check if filter is blocked
3. Check ambient Temp. and
water temp. is over limitation
blowing area is 1. Check if the blowing area is
blocked open
2. check if the evaporator is
blocked blocked
3.check if the coil sensor
position was resistance value is correct
changed
1.Ceheck if refrigerant system
is leaking
2.check if the sensor
changed
resistance value is correct
50
Diagnosis
1. Open the valve
2. Change a new flow switch
3.Clean or change a new filter
1. Reinject water or change to a
new pump of larger water flow;
2. Change a new high-pressure
switch
3. change a new filter
4.Change a new EEV
1.Amend the leakage and
reinject the gas
2.change a new filter
1. Put away the blow area
2. Clean the evaporator
3. Change a new sensor
1.Amend the leakage and
reinject the gas
2.Change a new sensor
