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

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).
