Hi Guys, My central heating timer is playing up, its a old mechanical clock type with little pegs to set the On/Off time, make unkown at this moment. I need some advice on fitting a new digital type timer. It only needs to control the Central Heating but most timers seem to do both CH and HW, would one of these be OK. I think there are 3 mains cables going to the exsiting timer (possibly one for theromstat, one for the boiler/pump and the mains supply?) although I'm just guessing! Can anyone advice a model or explain how to wire a new one up. I can post more info on my old model when I get home if this helps.
thanks in advance
