Grundfos MAGNA 25-40N pumps are 'A' Rated/EuP Ready and Variable Speed. Utilising automatic control of differential pressure through adaptation of pump performance to actual heat requirement without the need for connection of external components.
The pumps are able to automatically control differential pressure and therefore provide constant or proportional pressure control as required, energy savings of up to 50% can be acheived when compared to non-controlled pumps.
This gives the MAGNA range an A Rated energy label.
The pumps can be controlled via Four control modes as follows:
* AUTOADAPT (self-regulating from "one proportional pressure curve to another") to optimise comfort and reduce energy consumption to a minimum
* Proportional pressure
* Constant pressure
* Constant curve (available through external communication
