Hey there, 

Sorry to hear about the issues that you're having with your thermostat, I'm sure it's confusing, but I'm happy to look into this for you. 

 

The E105 error means that your Nest Thermostat is not receiving power from your system. I would suggest reviewing this article for troubleshooting steps. 

 

Please let me know if you have any further questions. 

Best regards, 

Garrett DS
