The Nest Thermostat E works with 85% of 24V heating and cooling systems, including gas, electric, forced air, heat pump, radiant, oil, hot water, solar and geothermal. 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 and emergency heat (O/B, AUX) Fan: (G) Power: (C, Rh or Rc) The Nest Learning Thermostat E is designed to work even if your home doesn't have a common C wire, but installation of a new C wire or the Nest Power Connector may be required in rare cases. If you have a dual fuel system it is strongly recommended to choose professional installation. |

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) 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 to choose professional installation. |
