Nest learning thermostat keeps restarting

[Gmangai2002]

My nest learning thermostat keeps restarting, it says to preserve battery. But it is connected to mains power. Any ideas why this is happening and how to resolve this ?

Hello Gmangai2002,

I'm sorry to hear that you're having an issue with your Nest Thermostat because it's not holding its charge. I'd be happy to take a look into this for you.

It's most likely that your system may not provide enough power or any power to either the thermostat or a specific wire, so your thermostat can't complete a circuit. To isolate:

• Are you seeing any wiring reports or message codes?
• Could you please share with us a photo of your thermostat's wiring?
• What's the make and model of your HVAC system?
• Is this a first-time installation?
• Check its power readouts under the "Technical Info" settings.

I'll look forward to your response.

Regards,

Mark
