Does anybody have a schematic for wiring the following system to a 16 or a 12 contact wiring centre? I don't have a programmer just a plug in timer that works on the HW and CH simultaneously, I have an Ideal Mexico Slimline boiler, Honeywell cylinder stat, Drayton room stat, 3-way motorised valve and a Grundfos Selectra pump. I'd appreciate a colour schematic or easy to follow wiring diagram, what I'm saying is it really does have to be an idiot's guide!! I'm having particular problems figuring out the wiring of the room stat and cylinder stat. Many thanks for what ever help you can offer.
