Heating system control circuits

I'd try the manufacturer for the particular system you're installing. I've used heatmiser systems (often badge engineered and sold by others too) and in some ways their UFH wiring centres are simpler than traditional S-plan and Y-plan systems, as you just connect everything direct to the marked terminals on the PCB. The heatmiser site has some good documentation anyway (e.g. https://www.heatmiser.com/en/heatmiser-system-drawings/)


Just be aware of the different types of 'stats (some are 12V 'networkable' and others 230V) with different wiring centres to match, and if the UFH covers more than one floor it's conventional to have one wiring centre per floor (usually located next to the UFH manifold).


That's all presuming it's a wet UFH system running from the boiler, rather than electric ones that are quite independent.

Well yes, so there I was expecting to do no more than fit a supply to an FCU, but the plumber expected me to do the wiring. The client hadn't a clue. In fact the manufacturers publish wiring diagrams so it wasn't difficult in the end.

Thanks Andy for the advice and yeah exactly the same here Chris.

Honeywell do (did?) an excellent one course. Best £20 I've spent.

Yes, they still do the standard course, and others, now they have a host of wireless products.

It is a good course, a little basic for some, but it gives a good insight into how all of the component parts interact.

Very good value, but I'd need to stay overnight. However, if you can read a wiring diagram, you should be able to cope.

Thanks everyone for the responses great help, going to look into that course. 


Cheers
