Nominal duty point Q

The nominal duty point is set using the Context button .

The optionally configurable nominal duty point for the differential pressure control ∆p‑v significantly simplifies adjustment by adding the required volume flow at the design point.
The additional input of the required volume flow at the design point ensures that the ∆p-v characteristic curve runs through the design point.
The slope of the ∆p-v characteristic curve is optimised.
