As per a previous post I've just replaced a 'hanging off the wall' (Did they come like that as everyone else seems to describe them like this too!) Switchmaster 805 with a Drayton Tempus 7. I wired in the equivalent from old to new CH/HW etc but I've got constant hot water. Heating seems fine - comes on only when supposed to and when I say 'constant' hot water it's not permanently firing up, but just occasionally to keep it at the set temp. Obviously I've gone wrong somewhere, but I marked each wire before undoing from the old timer so I'm not sure where.
There are 4 wires leading into the backplate, the mains, the boiler, the HW/CH/Both switcher from the airing cupboard, and what I presume is the thermostat from the front room. Can anyone advise the colour coding of the wires for each cable I should have in each point of the Drayton so that I can see where it's going wrong?
Many Thanks....
