Grundfos UPM3 Settings

UPM3 Auto Settings


For Radiators with TRVs it will be proportional pressure
For underfloor heating it will be const pressure
For fixed speed setting it will be const curve

If there is an external pump being used set to proportional pressure maximum curve and leave underfloor heating manifold on constant pressure curves, autoadapt ok. Otherwise speak to UFH manufacturer for recommending setting.
