Hi @Kurek,

Thanks for posting here in the community. I understand your concern about connecting your Nest Learning Thermostat to a furnace with only two wires. I'm happy to help!

To better assist you, Would you mind sharing a picture of your current thermostat wiring?

In the meantime, let's check a few tips:

• Installation: Nest Learning Thermostats can generally operate with just two wires. However, if you experience power issues or frequent battery drain, installing a C-wire is recommended. Visit our Help Center to learn more about Learn about the common or C wire.
• Compatibility: To check if the thermostat is compatible with your system. Refer to this article: Compatibility Checker.

Keep me posted.

Best regards,

Melany
