Thermostat raises temp in the middle of the night with all schedule deleted

[Jbenatar]

My nest has no schedule on it yet raises the temperature in the middle of the night. I’ll wake up to it at 5am with it having been raised from 69 to >70 without my approval. How do I fix this?

Hi Jbenatar,

Thanks for posting. I'm sorry for the inconvenience that you are experiencing with your thermostat. Don't worry I'm here to help.  I just need to ask: 

Could you please tell me what type of thermostat do you have? 

Regards,

Jenny
