the heat pump doesn't work
Problem:
the screen does not light up and the fan/compressor doesn't make a sound
Observation:
Possible cause
No electrical power supply
Problem: the heat pump works normally but there is no or insufficient heating
Observation: The screen displays the temperature but no error codes
Possible cause
1. In sufficient capacity of the heat pump in proportion to the
size of the swimming pool
2. The compressor works but the fan doesn't
3. The fan works but the compressor doesn't
4. The heat pump has not been placed on an optimal location
5. Faulty temperature setting
6. By-pass not adjusted
7. Massive ice formation on the evaporator
8. Not enough refrigerant
The heat pump works normally but the water is cooling down instead of heating up
Problem:
The screen displays the temperature but no error codes
Observation:
Possible cause
1.The wrong mode has been selected
2. The controller is out of order
3. The 4-way valve is out of order
the heat pump doesn't stop
Problem:
the screen displays the temperature but no error codes
Observation:
Possible cause
1.Wrong setting of parameters
2. Pressure switch out of order
3. Electrical failure
Solution
Check power supply (wiring, fuses,
Solution
1. Install a larger sized model or an extra heat pump.
Cover the pool to limit heat loss
2. Check the electrical wiring of the fan. Replace the
condenser or the fan motor if necessary.
3. Check the electrical wiring of the compressor.
Replace the condenser or the compressor if necessary.
4. Make for sufficient air circulation(see manual for
details)
5. Set the correct temperature
6. Have the by-pass readjusted by the installer
7. Have the settings for automatic defrost control
checked by the installer
8. Have the heat pump checked by a refrigeration
technician
Solution
1.Verify the parameters, select the correct mode
2. Check the voltage in the electrical wiring to the
4-way valve. If no electric potential is measured,
replace the controller
3. Check the voltage in the electrical wiring to the
4-way valve. If electric potential is measured,
replace the coil. If the problem persists, have the
heat pump checked by a refrigeration technician
Solution
1.Check the set parameters and adjust them if necessary
(settings just above the capacity of the heat pump)
2. Check operation of the pressure switch by turning
off the filter pump and restarting it. If the heat pump
doesn't react to this, the pressure switch must be
adjusted or replaced.
3. Contact your installer
