Ooooh!
I'm just guessing here, but maybe this isn't your average domestic UFH installation?

If a person or company contracted with you, two years ago, to install a working underfloor heating system using the Delta controller, and you still do not have a working system, then they are in breach of contract and you can sue them."If the 4 port valve is unused and they changed the design, then they should take the valve back and reimburse you the cost."
This is only one dissatisfactory aspect - it took nearly 2 years to get to the stage of all the original parts ordered actually being delivered and this is when they had sent it to a different designer, who then changed the port spec! I even tackled the chief honcho at one of the trade shows - very concerned etc. etc., but still not a good outcome for me! Have already bitten the bullet for this, so chose to not deal with them again!
So it's Plan B then! Back to you earlier post.thanks for your thoughts here re:- my rights etc. ...y when I said originally this was " a long standing headache "- it has been since 1998, it was re-designed etc., in 2000, last dealings with the company on any paperwork is 2002 - so i have lost the 6 year rule on statutory right a while back.
You will need a four core heat resistant cable. B&Q sell them, Tower brand. Brown to Ls, Blue to Ns, Green/yellow to Earth. The fourth core, usually yellow, will connect to the Lr terminal of the boiler."1. Spur to boiler; Ls, Ns wiring centre 1 and 2, earth from boiler or elsewhere to wiring centre 3 ".
Think I prefer this option so the CH is all turned off via one spur if needed.
Did it to help me understand what was going on."This diagram is based on yours and shows the system layout. Can you check it's correct. "
yes this is correct - and your drawing is so much better than mine!
All external connections are made to the WG100, not directly to the Delta"Do you have just the Delta controller or do you have the WG100/200 enclosure as well?."
! have the WG100 enclosure as well
No. But I would be consistent, i.e use the same colour when connecting to the same terminal."The left hand set of numbers are all sensors e.g:
KF = boiler temperature"
Does it matter which way round the wires go ? eg: KF 6L+ 10N or 10L + 6N? -( i am looking at the layout in the cover panel for the Delta as per the image uploaded earlier.)
This is where I confess to getting lost."The right hand terminals are where the valves and pumps etc connect."
O.k that makes sense - so if these are all coming from the wiring centre is it for example, grey, brown or orange of the HW valve to 12 of the Delta?

1. Did the installers provide a wiring diagram or a layout diagram?
3. Is the mixing valve connected as in my diagram, i.e the middle connection connects between valve and pump?
2. What make and model is the mixing valve?
4. Is the mixing valve wired up - if so how?
5. Can you confirm that the two room thermostats are not wired up.

What other numbers are there on the valve?
How big, (cm x cm) is the layout diagram you took a pic of? Some of it is missing so,
second 3-way valve in the 1st floor circuit. I had wondered why your diagram did not show one. Can you confirm it is there?
It looks like a diverting valve but looking at the flow arrows, the flow will be the opposite way.
three way valve shown in the drawing should be a diverter valve as norcon has noticed not a mid position as marked on drawing
