3 generation thermostat sometimes will not turn heat back on

[accsupt1952]

Why will my heat sometime not turn back in at nite? I have cleared all my settings but I have to move Temp up for furnace to restart

I came here for the same issue. I have cleared all settings but at the coldest part of the night it automatically goes off.

Please provide some detail about how you are trying to tell the Nest what temperature you want during the night.

Do you have presence sensing turned on (or Home/Away Assist)?  it's possible that the Nest incorrectly decides that you're Away, and lowers the temperature to your Eco or Away setting.  If you turn off presence sensing, does the Nest perform better?

Are you running the Nest on a schedule that calls for the same temperature all night?  Even if you didn't set up a schedule, there may be a default one in there.  See if there's a set point with a cold temperature in the wee hours.

Hi folks,

I wanted to stop by and see how I could help.

Thanks for assisting, @CBFox.

@accsupt1952 and @RyanM1, I did find a helpful article with some troubleshooting steps for when your thermostats are changing their temperatures or modes randomly. Please let me know if that helps, or if the issue still persists.

Best regards,

Mark
