Okay so update, I've got it working, but if I turn the boiler thermostat up it bypasses the hive and turns the heating on constant, so I'm only able to use the hive with the low heat setting on the boiler?
Hi, having a bit of trouble
Boiler has a manual timer fitted that has never been used, do I wire the hive up to that or remove the link between 7 and 12 and put it there.
