Hi, I have just replaced the room thermostat on my oil fired boiler, with an RS1. It has 2 live wire connections and an earth, I had to get this type as I have a standard 3 core flex to the stat. I believe I have wired it correctly, however it has blown the 13amp fuse in the main boiler supply twice and tripped the RCD fuse for the sockets. Any advice please?

you've quite obviously wired it incorrectly then.. despite your claim..
post a picture of the wiring in the stat and at the wiring center / boiler..

Hi, thanks for the reply, taken a photo, which I have uploaded into an album, but not sure what to do with it so you can see it. I have only taken 1 of the room stat, as I did not touch the junction box. There are 3 terminals, I have put the brown live to the far right, viewed from the front, blue to the middle and earth to the left terminal. Is that any help? I feel such a plonker!

Dear London Boy, I think you are right, the green/yellow is not as it seems, it is old wiring, certainly 10 years old, the boiler was replaced 4 years ago, but none of the ancillary electrics, stat, etc. Any help would be gratefully received.
to post a picture, click where it says "show my images" under the reply window.. then just click the picture you want to put in the post..
and you need to take the earth wire out of the terminal.. it's a change over by the looks.. doesn't require an earth.. you're just shorting it out..

That stat is definitely a changeover switch, no earth required.
It's also a very cheap and nasty effort.
How is the other end of the cable connected - or, what make/model was the old thermostat?
