7.2 Selection of pump flow rate
• Select the control mode (see 6.1).
• Preselect the pump output (delivery head) depending on the
need at the setting knob (Fig. 1, item 2).
• If the nominal delivery head is not known, we recommend
starting with the setting 1.5 m.
• If the heating output is not adequate, gradually increase the
set value.
• If the heating output is too high, or flow noises occur,
gradually reduce the set value.
• Select automatic night reduction mode, i.e. switch on or off
(see 5.1).
8 Maintenance
Maintenance and repair work should only be carried out by
qualified specialist personnel!
Warning! Danger of electric shock
Prevent dangers through exposure to electrical currents.
• For all maintenance and repair work, the pump must be
switched off. It must not be possible to switch it on again
without authorisation.
• In principle, damage to the connection cable must only be
repaired by a qualified electrician.
9 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,
