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 * connector

can accept one of these wires: W3, E, HUM, or DEHUM. The AQ+ and AQconnectors

can accept 1-wire or 2-wire VENT, HUM, or DEHUM.

Power

Compatibility

Patented Power Sharing technology

Nest thermostats have a patented Power Sharing technology, which means

that unlike other smart thermostats, they can be installed without needing

a C wire in the vast majority of homes.

The Nest Learning Thermostat has a Power and System test that will let you

know if more power is needed. If so, you can install a C wire or Nest Power

Connector to ensure the thermostat always has enough power.

A C wire or Nest Power Connector can always be installed for added

certainty and reliability if you feel like there’s a risk of power loss or

accidental system activation.

The types of systems that will require a C wire or Nest Power Connector

can be found here.
