Hi im trying to wire a Salus RT000RF to a Aztec Gold Electric Boiler. The Salus has a live and neutral feed from a fused spur and a No and COM connection. Ive added a picture of the wiring diagram... 00000000_000000 It's clearly work in progress. The (white) bracket holding the horizontal pipe (black) is broken, and a uniform colour scheme for the three pipes would look better. Tied0 This is very clear. Those are proper concrete blocks not light concrete? Blocks seem suitable as I can get an uncommon depth for bricks (i.e. approximately 00/00cm)
