Compatibility

Nest Thermostat works with most 24 V heating and cooling systems, including furnaces, air conditioners, boilers and heat pumps with either forced-air or radiant delivery.

Heating and Cooling: one 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)

Some systems, including heating-only, cooling-only, zone-controlled, and heat pump systems, require a C wire or the Nest Power Connector. Go to g.co/nest/cwire for details.

Professional installation is strongly recommended for dual fuel systems.

Compatibility

The Nest Learning Thermostat works with 95% of 24 V 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 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 or the Nest Power Connector 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 that you choose professional installation.
