Hello all
Spent a while earlier popping off faceplates etc and this is exactly what i have on my current heating system..
obviously i'm no spark/plumber so please excuse the diagram, I would just like a little help to better understand why the system is wired this way.
What confuses me instantly is that everything I read about adding roomstats/programmers to my worcester combi requires the mains from 3a switch going to boiler then from boiler back to programmer etc.. like this pic in the manual for my boiler:
For a nest setup would I need to get a new cable put in to the boiler..?
Thanks
