I've tried 2 other types of stats and all have the same result, the
heating ignores them when room reaches temp.
I've just changed the stat for a Honeywell CM900 and again I get
exactly
the same result. If I move the slider to off on the EP3002 everything
closes fine.

I thought maybe I'd wired the stat wrong so I rewired it and now I've
popped the motorised valve (Myson Power Extra MPE228).

I've ordered a replacement valve and EP3002. See how we go?


Keep playing with it, keep breaking and changing parts... you'll
eventually
change something and accitentally "fix" it, *OR* you can call you local
Master Tech and get the problem corrected the first time and be done
with
it.


Years ago in the TV repair business we called them "Tube Changers". ^_^

TDD

I recall a tube tester at my local drug store, but I am a little young
to remember the big picture. Was "Tube Changing" frowned upon back then
(mid-late 60's?)?

A good repairman would, given the schematics and a VOM, be able to
determine _which_ tube to change a priori, rather than just swapping out
tubes until the TV works again.

Thats been my point all along for HVAC systems... A good tech can diagnose
the system, show you what the problem(s) is/are, correct those problems with
parts from his well stocked service truck, and warranty those repairs .....
usually for 1 year.

You are fortunate that you can do the work for yourself, and don't have
to rely on locating a good tech. As we have discussed before, the
waters are treacherous!



(although I will admit to using the swap technique to fix a mainframe
once in Brussels).
