Adjustment of the CPB is related to the cooling media used. If water is used
as cooling media instead of oil, the CPB is set at 250 (%). If air is used as
cooling media instead of oil, the CPB is set at 100 (%).
Adjustment of DB is dependent on the system requirements. A more positive
value of DB will prevent unwanted cooling action, but will increase the
temperature overshoot. While a more negative value of DB will achieve less
temperature overshoot, but will increase unwanted cooling action.
