Nest thermostat batteries always low

Pbroberts2

I have had my nest thermostat installed for 2 weeks. I has preformed well, however, I have had to replace the AAA batteries 3 times! It seems to have central power because it powers up without batteries in the device. Looks like the wall power is a c-385 wire and is getting 37V. Can someone please tell me why I am going through batteries so fast and how to fix it?

Hi Pbroberts2,

 

Thanks for reaching out and we're sorry to hear about what's happening.

 

The new Nest Thermostat requires AAA batteries for back up. To have a stable power to your thermostat, it is necessary to have a C (common wire) connected to it. Could you check your wiring and see if there's a C wire or if there's an available wire that is not yet inserted?

 

Best regards,

Ryan
