    Honeywell and Danfoss Valves

    Had a major refit of the CH system by a contractor, a bit annoyed because of the way it has been done. The electrician has completely ignored the wiring guide for the centre and done his own thing, makes it a bit of a pig to sort out so now wish I had done it myself. Anyway, stupid question...

    Honeywell 3 port valves

    V4044 vs V4073 I found a boxed V4044 on site today (vacant property). Looking at the spec, these are not a mid position valve so where would you use one?
