You'll need a C-power adapter to power and charge the Nest.

Hey folks, 

Thanks for answering and for your recommendation, johnCNA. 

@goose0627, I just wanted to drop by to check if everything is covered here. If you still need our help, could you provide the make and model of your HVAC or old thermostat? Also, please upload a photo of your old thermostat wires so we can take a closer look into it. 

Best,

Hi, 

Since it's been since this thread was last updated, we'll be locking it if we won't hear back from you again within a day. Should that happen, feel free to create a new one if you have more questions or have other concerns in the future. 

Best, 

Melba
