I have just ahd a new boiler installed by a freind.. The wiring i have to do myself.. I have an open vented system with a standard boiler. The boiler wiring diagram shows where the external pump is connected to on the boiler electrica input etc. but i have 2 motorised valves and a honeywell 7 day timer. I do not want this timer so am going to get rid. one of the motorised valves is for hot water and as such i dont need it so will leave it unwired. However the motorised valve for the heating is a bit of a mystery,, where do wire this to, do i connect it to the same place as the pump is wired to (3 wires) so when the boiler turns on the pump it also activates the motorised valve, or can i leave the valve ???????
