Index circuit Δp-c

An optimised constant differential pressure control is available for “index circuit Δp‑c”. This differential pressure control ensures supply in a widely branched, possibly poorly balanced system.
The pump takes into account the point in the system which is the most unfavourable to supply.
For this purpose, the pump requires a differential pressure sensor which is installed at this point (“index circuit”) in the system.
The delivery head must be adjusted to the required differential pressure. The pump output is adjusted to this point as required.

NOTICE

Noise may occur in the system. Hydronic balancing is recommended.
