    Guys, thanks for all your re-assurance and advice. I have returned the unit, and ordered a replacement of the same type. I will post the results when it arrives so we can all learn from it. Cheers

    Honeywell CM907 room 'stat swap out

    Yeah, just tried that, I joined the brown (live) and Black (sw live) together and the boiler fires up. Separate them and boiler stops. This was done with the cables coming out of wall at room stat end, but this is the same as you suggest when saying join A to B with a piece of wire. Kind of...

    Honeywell CM907 room 'stat swap out

    Just another slant on this simple swap..... I thought maybe the relay in the new Honeywell may be knackered, hence the reason for not switching off the boiler. So I've rigged it up to light fitting, neutral to one side of light, live into position A on the Honeywell and out of B. Clicks on and...

    Honeywell CM907 room 'stat swap out

    Honeywell CM907 room 'stat swap out

    Thanks. I will get the screwdriver out !!!! Just for my own knowledge, why does the old one appear to have the Neutral linked to terminal 1 (Black wire, switched live) via a resistor ? Surely when the unit switches and calls for the boiler the N is joined to the switched live ?? = Bang !?

    Width of timber required for stud wall

    Woody Thanks for the quick reply! I was trying to get it as close to the brick width to help the plasterer out. I was told he would prefer it that way!?

    Hi, first post here so please bear with me! I am going to block up an internal doorway with a stud wall. The door is out, and the frame has been removed. I can see a lintel, so thats a good start! My question is relating to the width of the CLS timber I need. The doorway is brick width (100mm)...
