    So its pretty much what I stated in post no4?

    When your hot water gets satisfied @60 degrees and the MVs for the CH open again are you not left with the same problem of scalding hot rads still or is the programme sorting this?

    HW is no longer being called from boiler, only CH, so it will run at the lower weather sensor controlled CH temperature.

    Welcome to the weird and wonderful world of weather compensation! The future.

    I'd better jump on the bandwagon so...

    looking for help regarding wifi heating controllers
    Current system is Vokera Mynute boiler, with 2 MVs for upstairs and downstairs with siemens timer no zoning, mvs are manually switched.

    Looking for recommendations on a wifi heating controller to allow for control of the 2 zones and hot water, ( will have to install 3rd MV)

    Regards

    John Daly

    Yep, that's what is supposed to happen. When the HW goes on, yes, the relays should knock off the CH. When the HW is satisfied, the CH should come on again.

    I have not done this myself, but I can't see why it wouldn't work.

    This is basically what my Viessmann four-pipe does, i.e., HW priority. Less wiring though the wiring is by no means completely trivial with the Viessmann either!

    Be interested to hear how it goes.

    Thanks a million to all who helped. Just wired one. Works perfect and very very simple to do
