lacquering for the public to marvel upon- but his electrical skills
are not)..
Anyway- I stumbled across your wiring diagrams using Honeywell 2 port
zone valves etc.

After a good read and a check at the birds nest of wiring I was left
with all became clear- I took a deep breath and re wired following
your illustration of how a system like mine is supposed to operate.

It worked a treat and my central heating is now up and each zone is
running as it should.

Thank you very much-your site is now in my favourite folder."
