Hi - does anyone know of a good book (or website) that clearly explains central heating 'interlock' theory, with particular attention to the wiring of room stat/cylinder stat/programmer/3-port valve/boiler/pump/wiring centre?
I have some books that touch on the subject and I have some manufacturers data sheets for specific items of equipment, but would like an explanation ranging from basic concepts to system fault-finding. Thanks.
