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
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
T2 water temp. Too low
protection under cooling mode
PP11
1. Water pump failure
2. Water piping blocked
3. Water flow switch seized
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
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.
