❺ Troubleshooti ng
• When the setpoint temperature is reached, the appliance stops heati ng: the water temperature
is higher than or equal to the setpoint temperature.
• When the water fl ow rate is zero or is not enough, the appliance stops: check that the water is
circulati ng correctly in the exchanger and that the hydraulic connecti ons are correct.
• It may be that the appliance has detected an operati ng fault (see § "5.2 I Error code display").
• If you have checked these points and the problem persists: contact your reseller.
• If there is no display, check the supply voltage and the F1 fuse and replace it if necessary
(see § "5.3 I Replacing the electrical box fuse (depending on the models)").
• When the setpoint temperature is reached, the appliance stops heati ng: the water temperature
is higher than or equal to the setpoint temperature.
• When the water fl ow rate is zero or is not enough, the appliance stops: check that the water is
circulati ng correctly in the appliance.
• It may be that the appliance has detected an operati ng fault (see § "5.2 I Error code display").
• It may be that the appliance has detected an operati ng fault (see § "5.2 I Error code display").
• Check that the automati c fi lling valve is not stuck in open positi on; this will keep supplying cold
water into the pool and will prevent the temperature from rising.
• There is too much heat loss as the air is cool. Install a heat insulated cover on your pool.
• Check that the appliance is the right size for this pool and its environment.
• Identi fy whether the noise is coming from the circuit or the circulati ng pump.
• If the noise is coming from the circuit:
- There must be air in the circuit; bleed the installati on.
- The water fl ow is too high; reduce the operati ng speed, see § "3.4.4 Operati on of the
circulati ng pump on Heat Line +"
• If the noise is coming from the circulati ng pump:
- There is air in the circulati ng pump; let it run. It will bleed itself.
- The water fl ow is too low; increase the pressure in the primary circuit and/or check the air
volume in the expansion chamber (if installed)
• The circulati ng pump is not operati ng correctly. Check that it stops when the setpoint
temperature is reached.
• Another circulati ng pump is pushing on the primary circuit. In this case, provide a solenoid valve
on the output from the primary circuit managed by terminals 19-20 (see § "2.3.1 Connecti ng an
external command to supply the primary circuit").
• Check that the circuit breaker is correctly dimensioned and that the cable secti on used is
the right one (see § "1.2 I Technical specifi cati ons").
• The supply voltage is too low; contact your electricity supplier.
