How to Install Nest Thermostat With 6 Wires (Replace a LuxPro)

Want to learn how to install a Nest Thermostat with 6 wires ?

You are in the right place. I replaced my LuxPro Thermostat and documented the entire process in this article. Here you can find everything you need.

Here's a picture of the final installation and everything is working fine 😉

Nest thermostats don't use jumper wires

Those are Nest words, not mine 🙂 

I found this information on Google support website.

Nest Thermostat Jumper

So, if your actual thermostat uses a jumper (just like the LuxPro), you don't need it for the Nest thermostat installation (more on that later in this article).

You don't need to use the six wires

That's right. You will use only 4 of the six wires connected to the old thermostat.

When I opened my LuxPro thermostat, I saw 6 wires connected to it, but then I realized that there's a jumper between two contacts (RC and RH) and they are not necessary for the Nest Thermostat installation.

The LuxPro thermostat has the following connected wires:

  • G = Green
  • Y = Yellow
  • RC = Red
  • RC = Jumper to RC
  • W = White

For the Nest Thermostat installation you will use G, Y, RC and W

The wires used for the Nest Thermostat

I removed the wires and the jumper from the LuxPro thermostat.

In my installation, the wires are color-coded as Green, Red, Yellow and White.

You can use the labels that come in the box to make sure you use the correct wires.

Now that you have all your wires labeled, you can install the Nest Thermostat.

How to install and wire the Nest Thermostat

After removing your old thermostat, you just need to install the new one.

Use the installation steel and trim plate and place the Nest base into place.
