Bit stumped and can't work out which way to do it. I have a Worcester Boiler , with 8 rooms underfloor heating , upstairs / games room normal radiators. I have put a zone valve on the upstairs / games room run so that underfloor heating can be set to run 24 /7 albeit low over night / during the day just to keep the block warm ish rather than heat from cold each time. I have a Honeywell STC 9100C programmer running the upstairs / games room but have yet to wire in the zone valve so its on manual at the minute. Underfloor heating needs 3 more room stats connecting before I can fire up so I am close. So the problem I have is wiring the Zone valve which I thought I could wire into the Honey well and it should work when the timer is on but the valve seems to have other ideas and I notice the heating was on this morning when the timer should have shut it off. Wiring I have Honey Well Earth Neutral Live Live -1 link Brown Wire -2 Blue Wire -4 these go to the boiler Live in and Radiator link Zone Valve I wired into Earth Neutral Live which powers valve then Grey into 2 and Orange into 4 assuming it would open when timer came on and switch off when timer closed But it doesn't Any ideas

So after the roof conversion comes the DIY finish it off , Roof is on watertight and basically finished but the decorating , heating and wiring need doing still. Also decided on underfloor heating so that has added a further complication to the situation , as having to live in the house while I do all of these things
