Warranty Summary

The HAYWARD heat pump pool heater is warranted for one (1) year for parts and labor, with extended warranties on the compressor and heat exchanger components, valid in Canada only.

Usage and Operation Summary:

  • LCD Controller: User-friendly interface for setting and monitoring heat pump functions.
  • Switching Modes: Easily switch between cooling and heating modes via the controller.
  • Parameter Setting: Adjust various parameters through the controller interface for optimal performance.
  • Clock and Timer: Set clock and timer functions for scheduled operation.
  • Keylock: Lock the keypad to prevent unauthorized changes.
  • Temperature Display Conversion: Switch between Celsius and Fahrenheit display.

Troubleshooting and error codes

Malfunction LCD Controller Reason Resolution
Water inlet temp. Sensor failure P01 The sensor is open or short circuit Check or change the sensor
Water outlet temp. Sensor failure P02 The sensor is open or short circuit Check or change the sensor
Coil sensor failure P05 The sensor is open or short circuit Check or change the sensor
Ambient sensor failure P04 The sensor is open or short circuit Check or change the sensor
Temp. differential between water-in and water-out is too large E06 Water flow volume not enough, water pressure difference is too low Check the water flow volume, or system obstruction.
Anti freezing under cooling mode E07 Outlet water is too low Check the water flow volume or outlet water temp. sensor
The first class freezing protection in winter E19 Ambient or inlet water temp. is too low
The second class freezing protection in winter E29 Ambient or inlet water temp. is too lower
High pressure protect E01 Gas System pressure is too high Check through the high pressure switch and the gas system pressure to judge whether the gas loop is blocked or the freon is suitable
Low pressure protect E02 Gas System pressure is too low Check through the low pressure switch and the gas system pressure to judge whether there is leaking or the freon is not enough;
Flow switch failure E03 No water/little water in water system. Check the water flowvolume, water pump and flowswitch is failure ornot
3times water-in and water-out temp.differece protectionin 30 minutes E06 Water flowrate not enough Check the water flow rate, or water system is jammed or not
Defrosting Defrost Code Display
Communication failure E08 LED controller and The PCB connection failure Check the wire connection
