Hi jdig,

Thanks for posting in the Google Nest Community forum. I'd like to know more about it. In what country are you located? Could you please check the wires connected to your system's control board? It will help us to see if there are other wires we can use for additional power to the Nest Thermostats. Also, it will help us to further check your system's compatibility with the Nest Thermostats. 

Best,

Jenelyn
