Hi, I need some help, I have bought a new room thermostat to replace the old one we had - the chap at the shop said that it will work with the boiler system i have - but it doesn't.
The thermostat I have bought is a Honeywell T6360 (b) I have wired it up to the best of my knowledge and the diagram given but everytime i turn up the thermostat the 3amp fuse blows thats runs to the boiler?
This is how i have wird it up - I have 4 wires = 1 single red wire, then a cable with 3 wires = 1 red 1 black and an earth. I have connected the single red into terminal one (live in) and connected the black wire - neut into terminal 3, 2nd live wire into terminal and earth to earth
THis prob makes no sense but any help will be appreciated
