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) 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 is 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. |
