25. Parameter description
Parameter HG41
Speed ZHP DHW
In DHW mode, the pump runs at this set value. Independent of pump control
type set in HG37.
Parameter HG42
Header hysteresis
The header hysteresis regulates the header temperature within the set range
by switching the heat source ON and OFF. The higher the ON / OFF temperature
differential, the higher the header temperature fluctuation around the set value,
resulting in longer heat source runtimes, and vice versa.
Parameter HG46
Header excess boiler water
temperature
The excess temperature differential between the header temperature and the
boiler water temperature during header heating is selected with parameter
HG46. The boiler water temperature continues to be limited by the maximum
boiler water temperature (parameter HG22).
