Google Nest Thermostat 3 Wiring Diagram

By | October 27, 2022



The Google Nest Thermostat 3 has become an increasingly popular choice among homeowners, thanks to its array of automation capabilities. But with all the bells and whistles comes a steep learning curve—namely, the wiring diagram for installation.

But fear not: Understanding the basics of the wiring diagram for your Google Nest Thermostat 3 is not as complicated as it may seem. After consulting experts and reviewing our own research, we’ve put together a comprehensive guide to help make your installation a breeze.

To begin, you’ll need to gather the necessary tools and supplies. These include a Phillips screwdriver, wire strippers, and a flathead screwdriver. Additionally, it’s important to check the compatibility of the Nest Thermostat 3 with your current system. For optimal results, be sure to use the right size wires and connectors.

Once you have the necessary supplies, the next step is to access the wiring compartment. Do so by removing the two screws that secure the wiring panel to the wall. Once removed, locate the thermostat’s wiring terminals.

At this point, it’s time to begin connecting the wires. Start by attaching the common (C) wire to the common (C) terminal. Then, attach the remaining wires to their proper terminals according to Google’s Nest Thermostat 3 wiring diagram. Be sure to connect the wires securely and make sure that no stray wires are exposed.

Now that you’ve connected the wires, it’s time to mount the Nest Thermostat 3 itself. To do so, line up the lower edge of the thermostat with the bottom of the wiring panel and press it into place. Once it’s secured, replace the two screws to hold it in place.

Finally, you’ll need to program your Nest Thermostat 3 according to your preferences. From the home screen, select “Settings” and then “Advanced Settings.” Next, enter your desired temperature settings, heating schedules, and other preferences. Save your changes and you’re all set!

It may take some trial and error to get the hang of the Google Nest Thermostat 3’s wiring diagram, but with a little patience you’ll soon be reaping the benefits of a fully automated thermostat. And don’t forget to keep your wiring diagram handy in case you ever need to refer back to it!
