HVAC System Compatibility

The Nest Learning Thermostat (4th gen) works with most 24V systems, including gas, electric, oil, forced air, heat pump, and radiant.

It can control:

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)

Fan (G, G2, G3)

Power (C, RH, RC)

Humidifier and dehumidifier (HUM, DEHUM)

Ventilation (VENT)

The Nest Learning Thermostat’s Star connector icon terminal can accept one of these wires: W3, E, HUM, or DEHUM. The AQ+ and AQ- terminals can accept 1-wire or 2-wire VENT, HUM, or DEHUM.

Use the compatibility checkerto 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 may be 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.

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)
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 to choose professional installation.
