Nest 3rd gen. Oil fired radiator system. UK Based.
All of this has been working in the past.
Nest will not fire up the heating either from a schedule, app or a twist of the dial
Nest WILL fire up the heating from the manual override on the heat link
Nest WILL boost the water from the app
Makes me think connectivity between app, thermostat and heatlink are good. Seems as though heatlink to boiler ignition are good because the water boosts. Not sure why the heating won't also come on.
Any ideas?
Thanks
