    Logic Puzzle (incorrectly wired 2-way switch)

    OK, Here it is.... This is how it is now (after the change I did last week). The red dotted lines represent wires that are live (I disconnected everything before checking with my multimeter). Anybody got any ideas? Thanks.

    Logic Puzzle (incorrectly wired 2-way switch)

    Cheers, If you could post it or send it to me, that would be great. I've tried the same today (with my limited knowledge of electrics). After reading both of your posts I intend to find some spare time and get my multimeter out over the weekend and identify which cables are going where, but...

    Logic Puzzle (incorrectly wired 2-way switch)

    Thanks - I've just tried this but things still aren't right. The double switch now seems to operate the lights correctly, but the single switch doesn't do anything at all (although lights flicker when operated) - whether the single's on or off, the double switch can turn on and off both lights...

    New Central Heating Programmer

    Thanks for the help (sorry if I've posted an obvious question but I did check the wiki and do some searches first). It looks like it might be easier replacing it with a ST799 to give me the ability to have different on/off times for different days...

    New Central Heating Programmer

    Hi all, I would like to fit a new central heating programmer although I'm not sure what I need. Here's a pic of it... Anybody got any ideas of what model this is and what a suitable replacement would be? I've got a normal (i.e. not combi) boiler... Thanks.

    Logic Puzzle (incorrectly wired 2-way switch)

    Hi all, Just wondering if anybody has any ideas on my wiring problem - a previous occupier has incorrectly wired the light switches in the lounge. There is a single switch at one side of the room, and a double (dimmer) switch at the other side. However there doesn't seem to be any consistency...

    Cooker Hood Ducting above Ceiling

    Thanks Richard, All done and ready for plastering tomorrow. Cutting a hole through the wall was a bit of a pain but I got there in the end.... The only rigid cylindrical tube I could find was some telescopic stuff (basically one tube inside another), but I think it will do the trick...

    Cooker Hood Ducting above Ceiling

    Thanks Richard, I called at B&Q tonight and spent a good while trying to find all the bits that connect together... I saw the kits that you mentioned, but although they were labelled as 3 metres, this consisted of 2 metres of rectangular duct and 1 metre of circular. They didn't have any...

    Cooker Hood Ducting above Ceiling

    Thanks, I've got a proper sparky doing the electrics and it is all being done under building regs anyway. I actually meant what kind of "ducting socket" I would need if you see what I mean - i.e. after the ceiling is plastered, should there be an end of one of the fittings poking out that my...

    Cooker Hood Ducting above Ceiling

    Thanks guys, didn't want to cause an argument :o When I get around to choosing a hood I'll be sure to pick one that looks like it will expel enough air. I'll try and install some rectangular ducting at the weekend. I've found a good link here...

    Cooker Hood Ducting above Ceiling

    Thanks, The width of my kitchen is only about 2.5m, so this is how far it would have to go. Is it OK to do this or is the electrician going to blow a fuse (sorry!) when he arrives to do the lights etc around it? Any advice on what size ducting I will need? I've not got the cooker hood yet...

    Cooker Hood Ducting above Ceiling

    Hi all, I am in the process of getting my kitchen refurbed. Currently my cooker is on an interior wall but I want to vent to the outside via some ducting. As my ceiling is currently down, is it OK to take the ducting across the kitchen to the opposite wall in between the (what will be)...

    Kitchen Lighting Ideas

    Thanks, they look ideal. I've also found some eyeball ones that go to 30 degrees here : http://www.asourceoflight.co.uk/lodownlights.htm. I guess I'll wait until the ceiling is on its way up to see whether 30 degrees will be enough.... Thanks again.

    Kitchen Lighting Ideas

    Hi all, We are having an extension built onto the back of the kitchen - the new part of the kitchen is to have a sloping ceiling at about 30 degrees with a velux window down the centre of it. I'm looking for ideas of how to light this half of the kitchen. One idea is eyeball spotlights...

    Illuminated Door Bell Push

    Thanks, I'll take the cover off and have a look inside and see if there are different terminals.... Push button ordered now so I'll wait and then see what I can do....

    Illuminated Door Bell Push

    Now I'm confused... I've managed to climb up and look at the transfomer - it's a Friedland 752 - it says "Primary 240v, Secondary 3-5-8v 1.0A". Presumably this means that it can supply the required 8 volts? Why would it supply different voltages, I'm just curious....

    Illuminated Door Bell Push

    Thanks - do you think I am better off getting my multimeter out and checking whilst the button is pressed to confirm that it's less than 12v?? I suppose I could just buy the flipping thing - it's just a bit of hassle ordering it, paying postage & returning it if chances are it won't work...
