6.5 About the limitation of water in temperature
Water in temperature

, 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 Error code Reason Solution
Inlet water temperature sensor
failure PP01 The sensor in open or short circuit Check or change the sensor
Outlet water temperature
sensor failure PP02 The sensor in open or short circuit Check or change the sensor
Heating condenser sensor failure PP03 The sensor in open or short circuit Check or change the sensor
Gas return sensor failure PP04 The sensor in open or short circuit Check or change the sensor
Ambient temperature sensor
failure PP05 The sensor in open or short circuit Check or change the sensor
Condenser gas exit sensor failure PP06 The sensor in open or short circuit Check or change the sensor
Antifreeze protection in Winter PP07 Ambient temperature or water inlet
temperature is too low
Low ambient temperature
protection PP08 Ambient temperature or water inlet
temperature is too low
Ambient temperature is too in
heating mode PP09 Ambient temperature is too high Stop the heat pump and wait
the ambient temperature at
less than Air 40
℃
( less 5
℃
in
allowance) The error code will
disappear automatically
Cooling condenser temperature
too high protection PP10 Cooling condenser temperature is
too high Stop the heat pump and wait
the
cooling condenser
temperature drop down
High pressure failure EE01 1.Refrigerant is too much
2. Air flow is not enough 1.Discharge redundant
refrigerant from HP gas system
2.Clean the air exchanger
Low pressure failure EE02 1.Refrigerant is not enough
2.Water flow is not enough
3. Filter jammed or capillary jammed 1.Check if there is any gas
leakage ,re
‐ fill the refrigerant
2.Clean the air exchanger
3.Replace the filter or capillary
Water flow failure EE03 or
"ON"
Low water flow, wrong flow
direction, or flow switch failure. Check if the water flow is
enough and flow in right
direction, or else the flow
switch could be failed.
