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.

Heating and Cooling: 1 stage of heating (W1) and cooling (Y1) and a second stage of
either heating (W2) or cooling (Y2).

Heat pump: with auxiliary or emergency heat (O/B, AUX)

Fan: (G)

Power: (C, Rh or Rc)

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.

Professional installation is strongly recommended for dual fuel systems.

Compatibility

The Nest Learning Thermostat works with 95% of 24V heating and cooling systems, including gas, electric, forced air, heat pump, radiant, oil, hot water, solar, and geothermal. This is based on data gathered through the Nest’s online compatibility tool.

Heating: 1, 2, and 3 stages (W1, W2, W3)
Cooling: 1 and 2 stages (Y1, Y2)
Heat pump: with auxiliary and emergency heat (O/B, AUX, E)
Humidifier or dehumidifier (HUM, DEHUM)
Fan 1, 2, and 3 speeds (G/G1, G2, G3)
Power (C, RH, RC, R)

The Nest Learning Thermostat is designed to work even if your home doesn't have a common C wire, but installing a new C wire may be required in some cases.

Note: Only one of the wires that go into the  connector (HUM, DEHUM, E, W3, G3) can be connected to the Nest thermostat. The 3rd gen Nest Learning Thermostat supports systems with either multiple fan speeds (G2/G3) or with multiple stages of heating (AUX/W2/W3) and cooling (Y2).

If you have a dual fuel system, a whole-home humidifier/dehumidifier, or a multi-speed fan, it is strongly recommended to choose professional installation.
