Differential pressure ∆p-v

The control triggers a linear change in the differential pressure setpoint the pump must ensure between reduced differential pressure H and H_set.
The controlled differential pressure H increases or decreases with the flow rate.
The slope of ∆p-v characteristic curve can be adjusted to the respective application by setting the percentage of H_set (slope ∆p‑v characteristic curve).

NOTICE

Options “Nominal duty point Q” and “Slope of ∆p-v characteristic curve” are available in the context menu [•••] of the setpoint editor “∆p-v differential pressure setpoint”.

Δp‑c is used in circuits with variable pressure and volume flows, e.g. radiators with thermostatic valves or air-conditioning devices.
A hydronic balancing is required in all circuits mentioned.
