Hesting works fine from the app and thermostat and schedule.Hot water
works fine from scheduleHot water boost can be activated from app,
screen goes orange but boiler doesn't fire up. No idea why?
I have the same problem. I think I solved it. Reset the thermostat. You
can do a full reset without losing data saved. Then reset the main nest
control box. Mine was in the airing cupboard. Keep your finger on the
middle nest button for around 20 sec...
