Hello. The mechanical timer is kaput on my lovely old combi. It’s a mech clock but not an M10 with “plug and play” but p/n 8716105047. Same controls but with 3 wires to. Terminal block soldered to the PCB. I’d like to add a wireless 2 channel like Drayton LP20 to allow easier control but this is wired via a ribbon with 5 cables (from what I can see).
I’ve attached a photo. Any suggestions?
