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 co
ntrol parameters if you have knowl
edge 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.
When a setpoint step change is specified, it may be that the optimum control would set a bath
temperature, which might significantly exceed the temperature desired on the external vessel. There is
a correction limitation, which specifies the maximum permissible deviation between the temperature on
the external load and the heat transfer liquid temperature.
