Temperature control
For PI control only:
The integrated time
determines the reaction time
of the control.
These times can be adapted to
suit particular circumstances.
If the cooling system is over-
dimensioned and therefore too
fast, shorter values should be
used. Conversely, under-
dimensioned cooling (slow)
benefits from longer
integrated times.
