im a heating engineer but it’s been a while since I wired up a system from scratch. We have sparkys on the firm who normally do it but this is for my system at home.
I have absolutely no problem with the theory of how it works and what connects to what but what’s got me scratching my head is that the boiler needs to be fused at 5A and the Honeywell controller needs to be fused at 3A. I’m planning on running the whole thing off a 3 pin plug and have considered putting a fused spur box next to the junction box to hold a 3A fuse to supply programmer only but don’t like the idea as it could get mistaken as being the fuse for the whole system.
Any suggestions?

put a switch fused spur in rather than it plugged in
