WE TAKE YOUR PRIVACY SERIOUSLY

We’re committed to being open and honest about how we use data. We’ll always ask for permission before sharing personally identifiable information like your email address, and we keep your data safe with industry-standard security tools. To learn more about our Privacy Policy, go to nest privacy.

Compatibility

Based on Nest’s online compatibility checker data, the Nest Thermostat works with most 24V systems, including gas, electric, oil, forced air, variable speed, heat pump, and radiant. It can control:

  • Heating: one, two, and three stages (W1, W2, W3)
  • Cooling: one and two stages (Y1, Y2)
  • Heat pump: with auxiliary and emergency heat (O/B, AUX, E)
  • Fan (G)
  • Power (C, RH, RC)
  • Humidifier or dehumidifier (HUM, DEHUM)

The Nest Thermostat’s * connector can accept only one of these wires: W3, E, HUM, or DEHUM. The Nest Thermostat is designed to work even if your home doesn’t have a common (C) wire. Rarely, installing a new C wire may be required. Professional installation recommended for:

  • Dual fuel systems (heat pump with furnace)
  • Whole-home humidifiers and dehumidifiers

Remove cover
Some covers pop off, while others need to be unscrewed.

Check your system
If your old thermostat is labeled 120V or 240V or has thick wires with wire nuts, your system is high voltage. Not sure? Contact support.

Remove any jumper wires
Jumper wires are short wires between two connectors. You won’t need them. An R wire can go into either RC or RH.

Label wires
Peel off the labels below and attach them to the thermostat’s matching wires. Use the white labels for W3, E, HUM, or DEHUM wires. The connector can only connect to one of these wires. See two names for each connector on your old thermostat’s backplate. Visit nest for help.

Disconnect wires and remove the base
After removing the base, we recommend gently wrapping the wires around a pen or pencil to ensure they don’t fall back into the hole in the wall.

Electrical boxes aren’t common, but if you have one, secure the steel plate to the electrical box with two of the short steel plate screws. Insert the screws into the long slots on the steel plate. Use the other two short screws to attach the Nest base and trim plate to the steel plate.
