How the pump works:
Should the room in which the pump is situated not be heated sufficiently, the speed of the pump will be too low, In this case, it is necessary to switch to a higher speed.
On the other hand, should the speed of the pump be set too high, unpleasant flowing noises will occur in the pipes and the throttled thermostatic valves? These noises can be eliminated by switching to a slower speed.
