Setting the control mode
The LED selection of control
modes and corresponding pump
curves takes place in clockwise
succession.
• Press the operating button briefly
(approx. 1 second).
LEDs display the set control
mode and pump curve.
Air venting
• Fill and vent the system correctly.
If the pump does not vent
automatically:
• Activate the pump venting function
via the operating button: press and
hold for 3 seconds, then release.
The pump venting function is
initiated and lasts 10 minutes.
The top and bottom LED rows
flash in turn at 1 second intervals.
To cancel, press and hold the
operating button for 3 seconds.
• After venting, the LED display shows
the previously set values of the pump.
Fault signals
• The fault signal LED indicates a fault.
• The pump switches off (depending on the fault) and attempts a cyclical restart.

Check mains voltage and
operating conditions, and request
customer service
Excessive module

Water is flowing through the pump hydraulics,
but there is no mains voltage at the pump
Check the mains voltage,
water quantity/pressure
and the ambient conditions
Dry run
Air in the pump
Overload
Sluggish motor, pump is operated outside of its
specifications (e.g. high module temperature).
The speed is lower than during normal operation
