Discuss UFH Pump - Always on? in the Plumbing Jobs | The Job-board area at PlumbersForums.net
I think the nest has an underfloor heating setting? It certainly has a "radiator" option. I think the trouble here is the pump has a permanent live, likely from a crossed wire with the grey on the 2 port valve... assuming there is one!
Does the pump run even when the boilers off?
