The Nest Learning Thermostat (4th gen) works with most 24 V systems, including gas, electric, oil, forced air, heat pump and radiant. It can control: Heating and cooling: Three heating stages (W1, W2, W3) and three cooling stages (Y1, Y2, Y3) Heat pump: Five heating stages and three cooling stages (O/B, AUX, E) Fan: (G, G2, G3) Power: (C, RH, RC) Humidifier and dehumidifier: (HUM, DEHUM) Ventilation: (VENT) The Nest Learning Thermostat’s Use the Compatibility Checker to check if your system is compatible. |
| Power compatibility |
Patented power-sharing technology The Nest Learning Thermostat (4th gen) is designed to work whether or not your home has a common 'C' wire. In limited cases (<1%), a C wire or Nest Power Connector is necessary to ensure that your HVAC system can provide sufficient power to the thermostat in all conditions. Go to g.co/nest/cwire for details. Use the Compatibility Checker to check if you may need a Nest power terminal or C wire. |

The Nest Thermostat E works with 85% of 24 V heating and cooling systems, including gas, electric, forced air, heat pump, radiant, oil, hot water, solar and geothermal. 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 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 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. |
