If you are planning to buy the Amazon Smart Thermostat or have recently purchased one for your house, you might wonder how to install and set up the thermostat. While it’s pretty straightforward to do the installation, which would hardly take one hour or less, you can call for a technician if you aren’t able to do it yourself.
But the main question is — Have you checked the compatibility of your Amazon Smart Thermostat before purchasing it? If not, we would recommend you to do so.
In case it isn’t compatible, you can ask for a refund or replace it with a new thermostat (of a different brand). The Amazon customer service is available 24 hours via phone, chat, or email, so you won’t have any difficulty replacing it with the new one.
That, however, is the last option. First, you need to be sure if the Amazon Smart Thermostat is compatible with your home or not. There are a few ways by which you can determine it and that’s what we are going to find out.
In this article, we have written a full guide to help you find out the compatibility of your Amazon Smart Thermostat with your HVAC system and smart home. Let’s get started.
Does your HVAC System have a C-Wire Connection?
Before we hop on to the compatibility checker rules, you need to make sure if your HVAC system supports a C-Wire connection or not. If not, the Amazon Smart Thermostat is not compatible with your HVAC system.
In the following steps, we are going to find out whether your HVAC system has C-Wire or not.
Step 1: Always turn off the power to the HVAC system at the breaker box or the system’s primary power switch before working on the thermostat.
Step 2: Remove the faceplate of your old thermostat and take a picture of the wiring connection.
Step 3: Ensure that the C-terminal, which receives electricity from the HVAC system, has a wire connected to it. Some modern homes may have an unused wire behind the wall plate if you don’t have a wire for the C terminal.
If you don’t see any unused wire behind the wall plate, it means your HVAC system doesn’t have a C-Wire. In that case, a C-Wire Adapter is necessary.
Step 4: If you come across an unused wire, identify it with the C sticker and attach the other end of the wire to the C terminal, which is sometimes labeled as “24V” or “24 commons” on your HVAC system’s control panel. Then connect the C terminal to the end of the thermostat.
You are good to go now. By following the above steps, you can check whether your HVAC system has a C-Wire or not. Now let’s find out whether the Amazon Smart Thermostat is compatible with the system or not.
Compatibility with HVAC Systems
It doesn’t matter if your HVAC system supports a C-Wire connection or not. You can always take the help of the C-Wire Adapter.
The Amazon Smart Thermostat is available in a bundle option that comes along with a C-Wire Adapter. You have to pay $75 for the bundle package, though.
Here are the steps to find out the compatibility of the Amazon Smart Thermostat with your HVAC system.
Step 1: Turn off the power to your old thermostat from the electrical fuse box.
Step 2: Remove the faceplate from your old thermostat. Some thermostats don’t need tools to remove the faceplate, but some are held in place with clips and screws In that case, unscrew it and remove the faceplate gently.
Step 3: Check for any high-voltage wiring labels that say 110V/220V, wires labeled L1 or L2, wires with stranded ends, or wires connected by wire nuts. If you are seeing any of these signs, it means the Amazon Smart Thermostat isn’t compatible with your HVAC system.
If there is no high-voltage wiring, you can proceed to the next step.
Step 4: The Amazon Smart Thermostat is compatible with the following terminals:
- R, RC, RH
- B, C, O, O/B
- G
- Y, Y1, Y2, Y2-X2, Y2-E
- W, W/E, W1, W1 (Aux), W2, W2/Aux
- Aux, X2, Aux/E
If your old thermostat was connected to the same terminals, it means the Amazon Smart Thermostat is compatible with your home.
After confirming the compatibility of your Amazon Smart Thermostat, you can now proceed to the installation process.
Compatibility with Smart Home Systems
We know whether the Amazon Smart Thermostat is compatible with your home or not. But now we are going to find out about its compatibility with smart home systems.
Alexa is the only way to operate the Amazon Thermostat. It’s worth noting that Alexa compatibility isn’t built-in, which means you can’t ask the thermostat to alter the temperature because it lacks a microphone. To manage the Amazon Thermostat with voice commands, you’ll need an Echo speaker or another Alexa-enabled device.
Alexa Hunches, a feature of Alexa Smart Home devices, are used by the Amazon Thermostat. It enables the thermostat to change the temperature automatically and to manage the temperature more precisely using data from your other Alexa devices. In layman’s terms, Alexa Hunches can learn from your thermostat or other Alexa-enabled smart device usage patterns and adapt appropriately.
It will be easier for Alexa to comprehend your preferences if you have more Alexa-based devices in your house.
However, if the Amazon Smart Thermostat is your first home device, Alexa will take some time to learn and comprehend you. Until then, you’ll have to make your own temperature changes.
While it’s disappointing to learn that you can’t control the device with Google Assistant or Apple HomeKit, as of now, Alexa is the only thing that it supports.
The Takeaway
While the above steps will confirm whether the Amazon Smart Thermostat is compatible with your home or not, in case you aren’t sure about it, you can take help from Amazon customer service.
Apart from your HVAC system, you can also check if your smart home system can support the thermostat or not. If you don’t have an Alexa-based setup, you will have to purchase an Amazon Echo or Echo Dot to control the device with your voice commands.
Lastly, always make sure you are checking the compatibility before purchasing the thermostat to avoid confusion.
