Temperature difference from basic-stage cooling
This parameter is used to define the actual temperature up to which additional-stage cooling is active.
The temperature value is specified as a difference from the setpoint temperature.
Additional-stage cooling is switched on when the difference between the setpoint temperature and ac-
tual temperature is greater than or equal to the value set here.
