We have an evo home in our offices and it's played up a bit which means we've had to learn.Thanks.
The kitchen rad is always hot so maybe that's connected somhow but I couldn't get it to react with the controller.
I didn't go that deep into the menus so haven't done a RF check so that will be next if I get a chance, I'm leaving them to grieve now as they have a few electric heaters and a log burner so should be warm enough.
Thanks people
