i'm from the generation that wants to make do and mend, but is prohibited by doing so because of laws that the older generation has brought in. A generation that wants to fix but is employed by a generation who instructs us to throw away and renew, in the name of economics.
I'm not having a dig, I'm just saying. And thanks for your replies.

Sounds like you've fallen in with the wrong crowd there - still plenty of repair going on I think (and as far as I know quite legally!) Not so long ago I was asked to 'look at' a VHS recorder (along with favourite tape jammed inside) - "clockwork" really isn't my thing, but still it was fixable. My PCs are still 'homebrew' using mostly reused components. Current "hobby" project is renovating a 100-year-old house.

From the programmer Hot Water fires the boiler, Central heating on needs to fire the boiler and turn the circulating pump on as well. This requires a bit of wiring along with a cylinder stat and room stat to control it all.

However to avoid confusion it all works best with a programmer like this http://www.screwfix.com/p/hors...tiara-programmer/18470 because the sliders controlling the heating and hot water mechanically interlock, so you cannot turn the central heating on without the hot water.

However it will work without the cylinder stat, but the boiler stays hot all the time the hot water is on.

If you follow the link to the instruction maual from the Screwfix website you'll find all the wiring diagrams.

That's great, thanks. But I'll be hard pressed to get it installed now - it was a job for an estate agent and I've already replaced stat and pump (costly).
You know the landlord is tight when he has laid the whole house with the same awful carpet!
