10. FAULTS, CAUSES AND REMEDIES

Pump does not run with the power switched on :
- Check the mains fuses,
- Check the voltage at the pump (check name plate data),
- Pump blocked:
• Switch off the pump.
WARNING ! Risk of scalding !
Depending on the temperature of the fluid and system
pressure, hot liquid or gaseous fluid may escape or shoot out at
high pressure at the bleeder screw. There is a risk of scalding!
• Close shut-off devices upstream and downstream of the pump and
allow the pump to cool down.
Remove the bleeder screw. Check the movement of the pump by
turning the slotted rotor shaft with a screwdriver and release.
• Switch on the pump.
• If the blockage does not correct itself automatically via the automatic
release routine, see the manual procedure described above.
Noisy pump operation
- Check differential pressure setting and adjust respectively.
- Heating capacity too low, possibilities to increase:
• Stepp-up setpoint value,
• Switch off night setback.
To briefly switch off night setback mode (check on control
operations) it is sufficient to just turn the dial button a little.
• On cavitation, increase system pressure within the permissible limit.
If no solution can be found, please contact your plumbing and
heating specialist or your nearest
representative.
