Compatibility

The Nest Thermostat works with most 24V heating and cooling systems, including furnaces, air conditioners, boilers, and heat pumps with either forced air or radiant delivery.
It works with conventional systems that have one stage of heating and cooling and a second stage of either heating or cooling.
It works with heat pumps that have one stage of heating and cooling and either aux or emergency heat.
And it works with HVAC fans.
The Nest Thermostat is designed to work if your home doesn’t have a common (“C”) wire. In some cases, particularly if you have a heating- or cooling-only system or use a zone controller, a C wire or other power-supply accessory may be necessary. See g.co/nest/cwire for details.
