Amazon Smart Thermostat is the first-ever product launched by Amazon in the thermostat market. It is equipped with Wi-Fi connectivity, humidity sensors, scheduling, and location-based features like temperature control. All of that will only cost you $60.

Being one of the cheapest smart thermostats on the market, it doesn’t mean you can’t trust the product. Amazon has partnered with Resideo, the parent company of Honeywell Home, a popular thermostat brand, to come up with its own smart thermostat.

If this is your first time buying a thermostat, you might not know how to install one. You do have the option to hire Amazon Home Services or call a local HVAC technician to do the installation. But if you are willing to do it yourself, you can take the help of this article, which will guide you through the entire process – from installation to set up on the app.

Let’s get started.

Few Things to Keep in Mind while Installing Amazon Smart Thermostat

Since you are installing the Amazon Smart Thermostat for the first time, you have to keep a few things in mind before installing the thermostat.

  • Check if the thermostat is compatible with your HVAC system or not. You would never want an unsupported device in your home. 
  • To check for compatibility, go to the compatibility checker by Amazon. It will tell you whether the thermostat supports your HVAC system or not.
  • Check if your home has a C-Wire or not. Most modern homes do have one. But if you don’t, you have to buy a C-Wire Power Adapter in order to run the thermostat.

How to Install Amazon Smart Thermostat

The installation process of the Amazon Smart Thermostat is quite easy and won’t take you more than an hour to complete. You just need a drill, a screwdriver, a pen or pencil, and a level.

Now follow the below-mentioned steps to install the Amazon Smart Thermostat.

Step 1: First, turn off the power to your old thermostat. To do that, switch off the HVAC fuse in the electrical fuse box.

Step 2: Open the faceplate of your old thermostat and check for high-voltage wiring. Remember, the Amazon Smart Thermostat is only compatible with low-voltage systems (24V) and not with high-voltage systems (110V/220V).

Step 3: When you remove the faceplate of your old thermostat, you’ll notice a bunch of connected wires. Before removing them, it’s better to click their picture, in case a problem arises.

Step 4: Start removing the wires and label each of them with stickers, which are provided in the Amazon Smart Thermostat box.

Step 5: Unscrew the base plate of your old thermostat and remove it from the wall.

Step 6: Take the base plate of the Amazon Smart Thermostat and place it on the wall. Don’t forget to pull the wires through the plate.

Step 7: Check with a level whether the baseplate is straight or not.

Step 8: Mark the location of the screw holes with a pen or pencil through the base plate.

Step 9: Drill through the marked spots on the wall and press the plasterboard anchors into the hole.

Step 10: You have the option to either cover the area of your wall with a trim plate (included in the box) or not. If so, you can place it over the base plate and screw it.

Step 11: Now connect the thermostat with wires placing them gently in their respective positions. Make sure there are no loose connections or the Amazon Smart Thermostat won’t work.

Step 12: Once you are finished, gently cover the face of the base plate.

Step 13: Bring the faceplate of the Amazon Smart Thermostat and attach it to the base plate.

Step 14: Go back to your electrical fuse box and switch on the HVAC fuse to bring power back to your thermostat.

Step 15: Once your thermostat is powered on, it will display ‘SEt’ or a temperature indicating that everything is done perfectly. You can now set it up on your phone.

FAQs about Installing Amazon Smart Thermostat

Here are the few answers to the common questions asked about the installation of the Amazon Smart Thermostat.

The wires are connected, but the thermostat isn’t getting any power. Why?

Check to see if the HVAC system’s circuit breaker or system switch is turned on. Ensure that the HVAC system’s circuit breaker or fuse was not blown during installation. If electricity was not switched off first, or if wire tips were touched during installation, the breaker or fuse might burst.

Remove the thermostat faceplate and double-check that your wiring matches the instructions in the Alexa app installation guide. If you photographed the wire during installation, double-check that the wiring arrangement matches that of your old thermostat.

It might resolve the problem.
