*The configuration of the key lock makes it possible to prevent the pump setting from
being changed on the display.
The system was designed for a certain duty point (full load point, calculated maximum
heating or cooling power demand). During commissioning, the pump output (delivery
head) is set according to the duty point of the system.
The factory setting does not correspond to the output required for the system. The re-
quired pump capacity is determined with the help of the pump curve diagram for the
selected pump type (e.g. from the data sheet).
NOTICE
For water applications, the flow rate value shown in the display or output to the
building management system applies. For other fluids, this value only reflects the
tendency. If no differential pressure sensor is installed (variant ... R1), the pump can-
not indicate a volume flow value.
CAUTION
Risk of material damage!
An inadequate volume flow can lead to damage on the mechanical seal; the min-
imum volume flow depends on the speed of the pump.
• Make sure that the volume flow does not fall below the minimum value Q
Approximate calculation of Q
Q = 10 % x Q x actual speed / max. speed

Carry out settings by turning and pressing the operating button. Turn the operating
button to the left or right to browse the menus or configure settings. A green focus in-
dicates navigation in the menu. A yellow focus indicates a configuration of settings.

face, e.g. by:
• Setpoint setting via analogue input AI1 ... AI2
• Intervention of building automation via digital input DI1
or bus communication
Flashes with active twin-head pump connection.
Navigate menus and edit content by turning and press-
ing.
Menu navigation:
