Electronic Control Fault Message Table
To assist in determining the cause of the error message, refer to the table below.
Error Message
Error
Code
Likely Cause
Elimination Methods
Inlet Temperature Sensor Fault
P01
The temperature sensor is open or short circuit
Check or replace the temperature sensor
Outlet Temperature Sensor Fault
P02
The temperature sensor is open or short circuit
Check or replace the temperature sensor
Ambient Temperature Sensor
Fault
P04
The temperature sensor is open or short circuit
Check or replace the temperature sensor
Coil 1 Temperature Sensor Fault
P05
The temperature sensor is open or short circuit
Check or replace the temperature sensor
Coil 2 Temperature Sensor Fault
P15
The temperature sensor is open or short circuit
Check or replace the temperature sensor
Suction Temperature Sensor
Fault
P07
The temperature sensor is open or short circuit
Check or replace the temperature sensor
Discharge Temperature Sensor
Fault
P081
The temperature sensor is open or short circuit
Check or replace the temperature sensor
Exhaust Air Over Temperature
Protocol
P082
The compressor is overloaded
Verify if the compressor system is operating
normally
Antifreeze Temperature Sensor
Fault
P09
The temperature sensor is open or short circuit
Check or replace the temperature sensor
Pressure Sensor Fault
PP
The pressure sensor has failed.
Check or replace the pressure sensor
High Pressure Protocol Protection
E01
1. Reduction in water flow, causing excessive
refrigerant pressure.
2. Failed high pressure switch or other
refrigeration system fault.
1. Clean pool filter and pump basket. Turn
heater on and off and retest. Check bypass
valve for correct setting.
2. Check the pressure refrigerant system
and pressure switch (technician required).
Low Pressure Protocol
E02
Failed low pressure switch or loss of refrigerant.
Check the pressure refrigerant system and
pressure switch (technician required).
Flow Switch Protocol
(NO WATER FLOW)
E03
No water/little water flowing through heat pump.
Check pool plumbing and ensure filter
pump is running.
NOTE: This is a normal error message that will be displayed when the pool pump is not running.
Waterway Anti-Freezing Protocol
E05
Water or ambient temperature is too low
Check the water and ambient temperature
Inlet And Outlet Temperature Too
Big
E06
Water flow is not sufficient through heat pump
Check the system for sufficient water flow
Anti-Freezing Protocol
E07
Water flow is not sufficient through heat pump
Check the system for sufficient water flow
Primary Anti-Freezing Protocol
E19
The ambient temperature is low
Check the ambient temperature sensor
Secondary Anti-Freezing Protocol
E29
The ambient temperature is low
Check the ambient temperature sensor
Comp. Overcurrent Protocol
E051
The compressor is overloaded
Verify if the compressor system is operating
normally
Communication Fault
E08
Communication failure between wire controller
and mainboard
Inspect the wire connection between the
remote control and main board
Communication Fault
(Speed Control Module)
E081
Speed control module and main board
communication fail
Check the communication connection
Low AT Protection
TP
Ambient temperature is too low
Switch off unit until ambient temperature
increases.
EC Fan Feedback Fault
F051
The fan motor has stopped running
Inspect the fan motor
