Sets the setpoint source
The setpoint sources can be selected between "Internal setpoint" (setpoint can be set in
the display), "Analogue input AI 2" (setpoint from external source) or a "CIF module".
NOTICE
A CIF module can only be selected as a setpoint source if a CIF module is
installed. If no CIF module is installed, the menu item cannot be selected
(‚greyed out‘). If the setpoint is selected via the "Analogue input AI 2", the
analogue input can be set via the Settings menu.
If an external setpoint source is selected (analogue input or CIF module), the menu item
"substitute setpoint" appears. A fixed setpoint can be specified here, which is used for the
control in the event of a failure of the setpoint source (e.g. cable break at the analogue input,
no communication with the CIF module).

No-flow stop: ON/OFF
If no-flow stop is switched ON, an additional setting item for configuration of “No-flow
stop: limit” appears.
When confirming the " No-flow stop " menu item, you can choose between switch OFF
and switch ON. When selecting switch ON, another menu item “No-flow stop limit” ap-
pears. The flow limit can be set here.
