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 on-line 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 rare cases.

Check if you’re compatible >

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 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, we strongly recommend professional installation.
