6.5 About the limitation of water in temperature
Water in temperature ≦ 7℃, the heat pump will stop operation.
Note : If the water filtration system is stop before the heat pump, the unit will down (security condition) and the
code EE3 or ON advertise on the controller.
It is important to program the heat pump link the time program of the water filtration system.
For restart the heat pump, turn off and turn on the electrical power supply to restart the unit.
7. Troubleshooting
7.1 Error code display on LED wire controller
Malfunction
Inlet water temperature sensor
failure
Outlet water temperature
sensor failure
Heating condenser sensor failure
Gas return sensor failure
Ambient temperature sensor
failure
Condenser gas exit sensor failure
Antifreeze protection in Winter
Low ambient temperature
protection
Ambient temperature is too in
heating mode
Cooling condenser temperature
too high protection
High pressure failure
Low pressure failure
Water flow failure

Error code
PP01 The sensor in open or short circuit
PP02 The sensor in open or short circuit
PP03 The sensor in open or short circuit
PP04 The sensor in open or short circuit
PP05 The sensor in open or short circuit
PP06 The sensor in open or short circuit
PP07 Ambient temperature or water inlet
temperature is too low
PP08 Ambient temperature or water inlet
temperature is too low
PP09 Ambient temperature is too high
PP10 Cooling condenser temperature is
too high
EE01 1.Refrigerant is too much
2. Air flow is not enough
EE02 1.Refrigerant is not enough
2.Water flow is not enough
3. Filter jammed or capillary jammed
EE03 or Low water flow, wrong flow
"ON" direction, or flow switch failure.

Check or change the sensor
Stop the heat pump and wait
the ambient temperature at
less than Air 40℃ ( less 5℃ in
allowance) The error code will
disappear automatically
Stop the heat pump and wait
the
temperature drop down
1.Discharge redundant
refrigerant from HP gas system
2.Clean the air exchanger
1.Check if there is any gas
leakage ,re‐fill the refrigerant
2.Clean the air exchanger
3.Replace the filter or capillary
Check if the water flow is
enough and flow in right
direction, or else the flow
switch could be failed.
Solution
cooling condenser
