Dan, please post up a close-up photo of your existing connections, that'll be the quickest way of helping you.

thanks tricky
seems I've opened up an even bigger set of problems i found a set of instructions on wiring the stat only to trip out the rcd unit and a fuse on the circuit, complete knob springs to mind and after changing the fuse im still not getting power to the boiler
so reckon its time to call someone in the know

Ach, don't beat yourself up mate, these things happen. These RCD/RCBs are as sensitive as a PM woman..............

Make Blue safe. Red and yellow go to 1 & 2. Probably doesn't matter which way round.

Sounds like you stuck the blue into 1 or two first time round.

cheers
