7.11.2
External control variable (External measurement probe)
You only need to read further here if you have connected an external temperature probe or the actual temperature is
read in from a module (and you have activated it as control variable according to Section 7.5.4).
Only modify the control parameters if you have knowledge of control techniques.
The control system for external actual values is implemented for improvement of the control behavior as a two-stage
cascade controller. A "master controller" determines the "internal setpoint", from the temperature setpoint and the
external temperature, passed to the slave controller. The control value of the slave controller controls the heating and
cooling.
