Hi,
I intend to fit motorised valves to all three zones (upstairs rads, downstairs rads, and hot water) but I will wire them with a boiler interlock so that the boiler will only fire when at least one of the valves is in the open position.
Do I need an automatic bypass valves as well or is this overkill.
Many Thanks,
3CC
