les asked how it would be wired with the relays, I think he realised it would over complicate things so maybe its just curosity.

hello chaps,
can anyone explain to me how you can wire a Y plan up so you can have low voltage coming back to the boiler. I understand how a S plan can do this as I've done it in my own house.
cheers

picasso mysterymans plan is correct if i was to stick with one pump.
but there is a 30 sq mtr extension currently being built at the moment and i will be installing ufh in this space
now at the very least i'll be using 2 pumps but more than likely it will be the 3
the controls were going to be the h37xl pack but i'm now using the h47xl pack which is for 4 zones
the ufh will have it's own pump and controls.
the conservatory has it's own pump and controls
and main house & dhw share 1 pump and have independent controls.
the company that i found in dublin that supply the relays are going to do 2 wiring diagrams for me for the h37xl & h47xl which incorporate the wiring diagrams from horstmann.
the problem i have is that i never had to use relays before on a heating circuit.
thanks

I thought the whole point of this post was to use 2 pumps? I know the s plan plus can do 3 zones but it cannot do what you were asking about, not quite sure why the idea of using relays is scary, they are just simple switches.
the problem for me is i 've never used any relays before
and yes i understand the orange switch wire goes to the relay
but i just thought that i switch wire would come out of the relay and go into the boiler and pump and that the neutral would just come from the wiring center to them
i was'nt planning on doing the ufh till next summer that's why the first post only concerned 2 pump's
thanks.

Had a bit of time on my hands this morning so had a dapple with paint
here is the diagram as promised if anyones interested

and heres how to do it with volt free switching on the boiler

You don't get low voltage from a Y or any plan, it will all be 240vac
More details may help.

I think he means how do you obtain voltfree switching to fire the boiler on a y-plan doitall
answer...... you use a relay to do the switching and energise it by the valve orange/cylinder stat connection

correct matt1, that is what i mean..the way I wired my S plan was everything was 240v right upto the brown on the 2 port then wired the low voltage wire from the boiler to the grey wire there for the grey putting low voltage on the orange.
still carn't crasp this three port one tho!! where are we getting this relay from?! ok here is how i understand it everything is 240v then orange wire is wired up to a relay then from the relay out and bak to the boiler low volts??
am I close

Volts free refers to the switching. and need a special stat.
Look at the Salus RT500 range for example.

A relay puts out what you put in,
