well you need all the wires to connect to a thermostat. If you can connect them all to one it might work, but it might not. There's no way to put two wires to 1 service, so you'd have to twist it around the other wire. That'd make putting the thermostat onto its housing difficult.

Also if the wires aren't running out of the same hole in your wall that'd be a problem too.

If you have two different systems and the thermostat wires for each of them are in a different location in your home, then you'll need two separate Nest thermostats. Here's a link to know how multiple Nest thermostat works in the same home: https://support.google.com/googlenest/answer/9254411

Moreover, we recommend using the Compatibility Checker tool on our support page to check if your system is compatible with the Nest Learning Thermostat or you may reach out to our support team for assistance here: https://support.google.com/googlenest/gethelp
