A mate of mine asked me to look at the wiring of a boiler in a flat he is doing up.
As I told him- I am hopeless with central heating.
the boiler is a WB- guessing a combi because there is only a boiler and room stat-no tank, cyl stat etc.
the rads have 'trv's' on them- not sure what these actually are- just know their there lol!
the boiler has a L,N,E from a 5a spur and then there a 3core flex coming out of it that has just been cut.
the Honeywell room stat is in the lounge the other side of the wall.
do I just need to connect the L and N from that 3core to the r.stat?
maybe before it was cut the earth was used as a live conductor too? (Wrong I know...)
any ideas will be great
