Wiring s plan from old set up y plan...?

[Notagainpike]

Hi all, so things are coming on now at last!
New 250 cylinder in loft all pretty much plumbed in.
F+E tank binned off, new ups pump, 2 new zone valves imstalled...
Now im up to wiring up, have done the immersion, so we have hot water, ive wired in the dual stat. I have me head roughly into what i think is correct...
Last night when i was pressing the advance on the controller, noet was happening....no red light to indicate and no boiler fire....
i did see when i moved the contoller, there are some jumper links on the back of the unit...do i need to move these when going from y to s paln??

So, i think its all right,
I have my browns to the blue, and red,
Which run back up to the out puts from cylinder stat and room stat..

So turn the heating on prog should give you 240 to the room stat

Turn the room stat up you should have 240v on the 2 port brown and the 2 port lever should go slack

Correct ?

Il check after my scampi and chips🤣
Just now, i called for hw, time i got to boiler, pump was running, boiler screen was live, but not lit up, boiler wasnt firing, cover off valve, lever had moved and pressing switch, pulled supply to brown, pump stopped, lever released, boiler screen shut down...

NB the colours of the cables except from the zone valves could be misleading to say the very least.

I recommend you confirm all the connections

does your boiler need PL and SL ?

Yes 330 does need both

Im not sure tbh. What happened. I took front off boiler, messed with the sensors on flow and return, i took the cover off the board, removed it, contact spray and cleaned all connectors, found a couple of small areas of corrosion, reassembled.
Re bled rads, bled the air valve on the hw coil return.
It fired on hw demand.

Going to let it run and warm for a bit. Then try the hot water side of things...
May not be home and dry yet, but its progress.
Again many thanks for all your help.
