I can appreciate that. At the time, I was a home owner with a broken timer, who went to B&Q and asked for a suitable replacement. I bought the one suggested, attracted by the 'same back plate, fit in seconds' sales pitch and fitted it. I knew nothing of central heating systems at the time and...

I can't comment on the 2 port from new set up, but can confirm the boiler we replaced with our current one was the original one to the house, a Baxi Solo. I can confirm that all the pipe work, cylinder and stat in the airing cupboard is original to the house which we moved into when only about...

I'll try to answe everyone's post individually so as not to ignore and or anything. Thanks for your advice, I get where you are coming from. A concern I have before starting again from scratch, and having looked at images online of the 'idiots box' is that some of the connections I don't have...

I'm trying. But I'll try harder.

Of course it doesn't help when you open the thermosat expecting to see terminals labelled C, 1, 2 and actually find 1,2 3 - introducing ambiguity as to what is what - is it safe to assume C is 3?

Thanks for your help so far - sorry if I'm frustrating you - I'm trying my best.

Just checked that T1 on the cyl stat (red in the picture) goes to nowhere - i.e it terminates in the choco block but there are no wires joining up with this on the other side - it's a dead end. T2 in the cyl stat (yellow in the pic) joins up with the brown/orange(?) wire from the 3 port valve...

Sorry, I thought I was asked whether the grey wire from the 3 port was connected to terminal 2 in the stat - it isn't, as per the picture I posted. I'm sorry if I've misunderstood the question, and I get that the colours are meaningless (except the 3 port grey wire it seems - people seem happy...

Given that the two spare wires are joined up at the mounting plate (might not as well be there) and might not lead to the airing cupboard - if I haven't actually got a HW off cable, I'm stuffed, right?

Indeed - a hornet's nest of vipers I think is the term. Difficult to know where to start.

Love it! Thanks.

This is my set up...

It is a modern(ish) house built in 1989, so I can absolutely confirm that every single aspect of it was built by amateurs. Wiring, plumbing, joinery, plastering - all of it is borderline hopeless. The wiring is original, we've lived here almost from new and the original timer I replaced in...

Here is a picture of the inside of the cyl stat - the blue wire on the right attached to number 3 joins up to the grey wire on the 3 port valve with no other connections going anywhere from this particular junction on the connector block. Does this help?

Someone has suggested I have a hot water priority system??? Not sure what this means, or if it is true, or what I do about it to get a CH only channel to work?
