Really struggling swapping the old wireless thermostat over to the hive one, initially the boiler wouldn't power up on demand, found a new wiring diagram now the boiler won't switch on at all, does anyone know of a wiring diagram I can follow?
Yes lots.
First, you're posting in the wrong part of the forum-Plumbing and Central Heating would be a better fit. [MODS Please move?]
Second, when you go to that forum do a Search for Hive Vaillant- you'll probablly find a long thread from someone else with the same problems
Enjoy
