Digistat scr wiring

[Careyp]

My Digistat scr stopped working and home emergency engineer bypassed it so heating running all the time. I now have a new scr but unsure which wires go where, wiring diagrams seem to have more wires than I have. Attached picture of current wiring, would be really grateful for any help

Can you post a photo of the new wiring diagram?

I unfortunately don’t have a diagram with the new unit, just been looking online and most seem to have a blue wire as well

The digistat SCR follows the usual single channel wiring layout.

Try moving the grey wire to terminal 3 (with power safely isolated first!).

Ignore wire colours, they mean bupkis in a heating system. Ok, so do you have a weblink to the receiver?
