    Hi guys.
    New to forum.
    I've recently moved into a new home 8 months ago (well not brand new),
    There's Vailant Ecotec plus in the upstairs landing cupboard. which has been fine until now.
    I can't get the heating to come on. The water is fine.
    I think it might be something to do with the CM927 or the BDR91 relay box .
    Have changed the batteries in the CM927, no joy.
    No lights on the BDR91, tried pressing the button for 5 secs etc, still no luck.
    Any help would be very much appreciated.

    As you might've guessed, I'm not too familiar with wireless control's. :D

    Not sure if anyone has looked at my post, but I went ahead and purchased a new CM927 & BDR91 kit.
    I know!!! taking a chance.
    I managed to install them.
    The rely box was a bugger to fit though, wired up correctly, and the front of the box just wouldn't go onto the backplate easily :( Typical of Honeywell to make things difficult.
    anyway, got it on eventually, but now have a steady flashing RED light on the bottom neon, and a steady GREEN one on the top neon.
    Have looked through the manual, but couldn't see a paragraph on this. Does say about re-binding Though.
    It can't be that surely being new set, could it?
    Help please?
