Hope someone can help, I have an old baxi back boiler with an SVC thermostat on the side of my hot water cylinder. I would like to change it for a newer stat with water temperature control so bought a sunvic replacement. Problem is that the old SVC stat has only 2 wires(and earth) but new sunvic has L1, L2 and Common connections. Can anyone confirm that it is C and L1 that i need to use.
