This is where we're going to go into detail and look at the steps on how to install a Nest thermostat. It's relatively simple and, as long as you don't skip any steps, you'll have your thermostat up and working in no time!

  1. Go to the circuit breaker and turn off the power to your thermostat so you don't short out the wires or electrocute yourself.
  2. Use the blue stickers that came in the package to label the wires. Make sure you look at the diagram to check you're labeling the right wires.
  3. Remove the wires from the old thermostat and unscrew it from the wall.
  4. Bring the wires through the Nest plate and use the little bubble level to make sure it's level. Make a mark so you know where it will go.
  5. This step is optional, but if you want to cover up the old screw holes then you'll want to install the trim plate.
  6. Use the screws and screwdriver that came in the package to install the Nest base into the wall.
  7. Put the labeled wires into the right spots on the Nest. A small tab will go down once you insert the wire correctly.
  8. Line up the small rectangle connector on the back of the Nest display with the rectangle on the base plate and attach the display.
  9. Go back to the circuit breaker and turn the power on.
  10. Connect the Nest thermostat to your Wi-Fi.
  11. Follow the setup instructions that you see on the screen.
  12. Set your temperature.
  13. Download the Nest app on your devices.
  14. Connect the Nest to your smart devices.

Caution Notes

While there aren't too many cautions to take into consideration, there are a few very important things you need to do. The first one is to make sure the power to the thermostat is not on before you begin working on it. This will help you not electrocute yourself or end up shorting out the wires in your home. The other important thing is if your old thermostat is either 120V or 240V, then don't try to install the Nest thermostat. This is also true if the thermostat has thick wires because the Nest won't work correctly.
