Hi Hugomenjivar,
Thanks for posting in the Google Nest Community forum. I'd like to know more about it. A few questions: in what country are you located? What type of system do you have? What is the make and model of your system? Please take a photo of the wires connected to your system's control board, ensure that the labels of the wires are visible. It will help us to check your system's compatibility with the Nest Thermostats.
Best,
Jenelyn
