Thanks for the neat graphic for the 2-port MOMO valve!

Don't suppose you fancy tackling the 3-port valve/Y-plan diagram ? ;-)

I actually did it in OOo draw (Open Office's VISIO-alike) but it came out a bit of a dog's dinner. (I've got the source file somewhere if you thought you could spruce it up.)

Yup, I did a couple of the easy ones. However the credit should go to Dave Osborne who did most of the better ones (all the Y/S/W Plan diags and their wiring diagrams). I will see what I can do with the other Y plan one.

Nice Y-plan/3-port diagram - real work of art! A few points: I notice you've included the other resistor - I assume you ascertained where it goes? And don't take it from my diagram which way round the diode goes - I didn't know and just picked an orientation arbitrarily! (Though it shouldn't matter which way.)

Ah, well I thought it had better match our other depiction of the mid position valve here ;-)

I see you've coloured the diagram corresponding to the zone valve wire colours (except white). It might be useful to have them labelled too, to emphasise that they are actually the wire colours (and also so one can print out a copy in B&W and not lose that info).

Yup, could do that and add a note that the colours are not totally "fixed" and may vary between makers.


To my brain it would make it easier to follow the control flow to have live, neutral and boiler+pump arranged so

Yup, could do. I wanted to get the IO at the sides, and was trying to group the mains in to be "close". Will see what I can do. --John Rumm 02:23, 27 August 2009 (BST)


Do you want to upload Bill's picture disc somewhere? I might look thru one day. Rapidshare et al with a password would work. NT 15:59, 22 June 2013 (BST)

Yup, I could stick some of them up somewhere (there are 4gig of them!), but he asked me not to redistribute the whole disc since it has commercially valuable stuff on it. I was also planning on uploading a batch of "might be handy" images to the wiki shortly - feel free to find homes for them in appropriate articles. --John Rumm 00:20, 23 June 2013 (BST)
