If an external setpoint source (analogue input AI2 or CIF module) is selected, the menu
item "Substitute setpoint" opens. A fixed setpoint can be specified here, which is used
for control in the event of a malfunction of the setpoint source (such as a cable break at
the analogue input or no communication to the CIF module).
After confirming the selected setpoint source, the "Control setting" menu opens again.
In the event of a malfunction, such as failure of the required sensor, an "emergency op-
eration" can be defined.
