I have a 15 year old Potterton floor standing boiler with integral programmer.
The programmer has slider controls that no longer function correctly.
I would like to change it for an externally mounted programmer.
The current programmer has a wire that goes to h/w out, a wire that goes to c/h out and a wire that goes to h/w out/off. It also has a 3wire plug that plugs into a socket on the boiler circuit board.
I fitted and wired up the original installation and have kept the wiring diagrams (except for the programmer that was supplied as a plug-in with no diags as I recall)
Can anyone tell me of a suitable replacement programmer and whether the connections would be similar to the existing (i.e. wire for wire)?
I assume that the 3 wire plug is simply the LNE?
It is a fully pumped Y system (mid zone valve)
