https://ibb.co/kX0staHi I'm trying to install a hive heating and hot water replacing a potterton ep2001. I can't find a wiring diagram for the existing programmer.
I'm after some help as to what wires go where. I assume the wires which go to the thermostat are no longer needed. Please see attached picture and any help is greatly appreciated. It's a oil heating system so I can't get British gas to fit it and working for electricity board I'd hope I'd be able to do this myself rather that get a domestic sparky in!
