Nest isn’t turning heating off and all the radiators are belting out heat. Have tried switching to manual on the heat link and then setting back to Nest App but nothing works. Have just had to switch the boiler off to turn the radiators off. Has anyone else had the issue and is it an issue with Nest or a boiler valve issue? Really annoying that it’s happened on a snowy freezing night as am now worried pipes could burst with no boiler on.
