Changing the pump output
The standard setting for the pump output is sufficient under normal
conditions or with the heating circuit distributor. With a measured T of
more than 20 K an adjustment of the pump output is desirable.
▶ Increase the pump output until T is 20 K ( § , 28).
-or-
▶ Reduce the installation resistance by installing a low loss header.
