Possible cause Solution
No electrical power supply
Check power supply (wiring, fuses,…………)
Problem
:
the heat pump works normally but there is no or insufficient heating
Observat
ion:
The screen displays the temperature but no error codes
Possible cause Solution
1. Insufficient capacity of the heat pump in proportion to the
size of the swimming pool
1. Install a larger sized model or an extra heat
pump. Cover the pool to limit heat loss
2. The compressor works but the fan doesn't
2. Check the electrical wiring of the fan. Replace
the condenser or the fan motor if necessary.
3. The fan works but the compressor doesn't
3. Check the electrical wiring of the compressor.
Replace the condenser or the compressor if
necessary.
4. The heat pump has not been placed in an optimal location
4. Ensure sufficient air circulation (see manual for
details)
5. Faulty temperature setting 5. Set the correct temperature
6. By-pass not installed 6. Have the by-pass installed by the installer
7. Massive ice formation on the evaporator
7. Have the settings for automatic defrost control
checked by the installer
8. Not enough refrigerant
8. Have the heat pump checked by a refrigeration
technician
Problem:
The heat pump works normally but the water is cooling down instead of heating up
Observat
ion:
The screen displays the temperature but no error codes
Possible cause Solution
1.The wrong mode has been selected 1.Verify the parameters, select the correct mode
2. The controller is out of order
2. Check the voltage in the electrical wiring to the
4-way valve. If no electric potential is measured,
replace the controller
3. The 4-way valve is out of order
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
Problem:
the heat pump doesn't stop
Observat
ion:
the screen displays the temperature but no error codes
Possible cause Solution
1.Wrong setting of parameters
1.Check the set parameters and adjust them if
necessary (settings just above the capacity of the
heat pump)
2. Pressure switch out of order
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. Electrical failure 3. Contact your installer
Problem:
water leak
Observat
ion:
There is a large amount of water under the
heat pump
