Underfloor heating + rads has left me stumped!

Just posted a guide to the worcesters (not sure you've seen it) ^^^^

I'm getting no cables to go live on my zone and manifold connections in the wiring centre and 240 to my grey and orange going to the motorised valves!

I'm doing my head in here!

The motorised valves will have 230V (around 5W power dis), so that s/b OK.

Dumb question, but do you have the programmer(s) for CH set to 24H (or at least know for sure it's on) and the stat turned right up

Thanks Topquark. I don't think there is any need now. When all else fails check ALL THE FUSES. I found a 5mA fuse dead in the zone controller. I don't think it was working in the first place as it's lit up like a Christmas tree now and I've not altered any of the wiring apart from the boiler connections.

Now all I need to do now is see if this nice thick slate floor will warm up!

I've not. Where is it? I'll print it off for future reference.

Cheers

If you have a peek at page 21, it's close to the kind of config you'll need, only dif is it uses a zone for the HW cylinder, but principle will be the same.

Bingo! I've found it.

I'll make this my bed time reading! lol

I make my fair share of school boy errors with central heating wiring so in all fairness do need to read up a bit more on it.

No such thing as a school boy error when you're following on from someone else doing the initial install (you have to revalidate everything)! They are becoming more complex but fundamental principles for each zone controlled are pretty much the same.

Are you're feet getting any warmer now? Heating systems can be a sod to get your head round at times. I've got to the point where i can do a S-Plan with my eyes closed yet I always manage to miss a control wire somewhere whilst cabling for a Y-Plan. Practice makes perfect as they say.

3 channel programmer - HW, RADS, UFH. (although you could use a regular 2 channel combining the heating)

Why would you put a channel for HW.?? Y would you restrict when the home owner can or cannot have hot water as this is heated on demand.?
