Hi.
I've taken a plunge and bought a Nest Learning Thermostat to replace my current Drayton Digistat SCR and RF3.
I'm having some trouble getting my head around the wiring as my set up doesn't seem quite as simple as the instructions would like.
I'll happily call someone out to get it sorted but if it's as easy as someone on here clarifying what wires go where, I'd be grateful.
I've attached a picture of the existing set up, and the thing that is confusing me is that the instructions fir the Nest seem to suggest there should be a wire from L to 2, then the switched live wire connects to 3 and N. But that seems to contradict the existing set up a little?
To clarify as well, it is a Glow Worm 30cxi combi boiler.
Any clarity would be much appreciated.
