(*) The configuration of the key lock makes it possible to protect the pump setting from
being changed on the display.
9.3 Pump operation
9.3.1 Adjusting the pump output 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 required 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 pressure sensor is installed, the pump
cannot indicate a volume flow value.
9.3.2 Setting on pump 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 indicates nav-
igation in the menu. A yellow focus indicates a configuration of settings.

previously exited menu will appear. You can continue to configure set-
tings.

any unconfirmed settings will be lost. Pressing the button again opens the
home screen on the display and the pump can be operated from the main
menu.
