I have a gas boiler in the attic and a cylinder water tank in the airing cupboard.
The programmer Danfoss FS715 started going faulty so I managed to buy a Danfoss CP715 to replace as its easy they just plug in to the backplate.
However after installing the CP715 and making sure the dip switches matched the FS715 I was unable to get the hot water to work. When I press for the hot water the central heating comes on instead. I presume its something to do with the wiring, I have attached a photo.
I don't seem to be able to buy a FS715 so can't do a direct swap, does anyone know if a FS715si would work? Or any other programmer with the wiring setup I have, thanks.
