• Nest thermostats are designed to work with most 2-wire 20 - 30V systems. You need to check what the color of the wire is for before you connect it on your Nest Thermostat. We recommend using our Compatibility Checker tool on this link to verify if your system is compatible: https://support.google.com/googlenest/answer/9246656 or you may reach out to us for assistance with your new Nest Thermostat here: https://support.google.com/googlenest/gethelp
