How to Wire a Thermostat without Causing a Mishap

1. Turn off the power

The first step of how to wire a thermostat is by going to the fuse box and turning off the power. You want to make sure that there is no electricity coming through when you try to work on electrical devices.

Make sure the power is completely off by testing that the existing thermostat doesn’t work and that the other electrical components of your house don’t work.

2. Remove the thermostat’s faceplate

After you’ve made sure the electricity is off, the second step of how to wire a thermostat is to remove the plate on the front of your existing thermostat. Depending on the thermostat, this could mean simply pressing a latch.

If it’s tough to get off, you’ll need to use a screwdriver.

3. Photograph the existing writing

Before you begin messing with the wiring, you need to take a picture of it. This is one of the most important steps of how to wire a thermostat successfully. Taking a photograph of the original wiring setup will help you resolve issues that come up if something goes wrong during the connection process.

4. Follow the manufacturer’s instructions

This is the step of how to wire a thermostat that requires you to look at the instructions in the manual that came with your new thermostat. Whether you are installing the Nest, Ecobee or a traditional thermostat, you can almost always find the instructions on the manufacturer’s website.
