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.
