7. Troubleshooting
7.1 Error code display on LED wire controller
Malfunction
Error
code
Reason
Solution
Low ambient temperature protection
PP0
Ambient temperature is
too low
Inlet water temperature sensor failure PP1
The sensor in open or
short circuit
Check or change the sensor
Outlet water temperature sensor
failure
PP2
The sensor in open or
short circuit
Check or change the sensor
Heating condenser sensor failure
PP3
The sensor in open or
short circuit
Check or change the sensor
Gas return sensor failure
PP4
The sensor in open or
short circuit
Check or change the sensor
Ambient temperature sensor failure
PP5
The sensor in open or
short circuit
Check or change the sensor
Temperature difference too much
protection water inlet and outlet
PP6
Water flow volume is not
enough
Check the water flow volume
or water jammed or not.
First grade antifreeze protection in
Winter
PP7
Ambient temperature or
water inlet temperature is
too low
Water pump will run
automatically for first grade
antifreeze
Second grade antifreeze protection in
Winter
PP7
Ambient temperature or
water inlet temperature is
too low
Heat pump will start heating
for second grade antifreeze
High pressure protection
EE1
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 protection
EE2
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
Flow switch closed
ON /EE3
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.
Inlet and outlet water temperature
difference malfunction
EE5
Water flow volume is not
enough, water pressure
difference is too low
Check the water flow rate or
water system is jammed or
not
Communication failure
EE8
Wire connection is not
good
Check the wire connection
