Really looking at the post Hive Wiring but don't want to hijack the post.
But we have just bought a new house to us, so have just finished visiting house with the idea of moving, and we looked at a few new builds, it seems many now have the heating zoned, dormitory and living area, well I say that, often the bathroom seems to be included in dormitory area, and for us of the 4 bedrooms upstairs only two used as bedrooms, one is an office and one a craft room, so would need moving from dormitory to living area. Seems to be a rather short sighted idea.
However out of interest how are they plumbed and wired? I can see the idea of a programmer which selects dormitory and living area areas and uses different times, however how does it turn the boiler off when not required? Most motorised valves have micro switches, but switching between two modulating thermostats just can't work out how it is done.
If using return water to control the boiler modulation, you need some thing to stop it cycling, the traditional method is a thermostat in a room normally kept cool with no outside door or alternative form of heating normally on ground floor as heat rises, so ground floor normally coolest.
Pre modulating boiler it would have been easy, programmer feeds thermostat, thermostat feeds motorised valve and motorised valve feeds boiler, but since the room temperature is now controlled with a TRV that will no longer work, so how is it done. Do they simply pretend it's not a modulating boiler and keep switching it off/on?
