✅ Is Your HVAC System Compatible?
Before getting started, confirm compatibility using the Amazon Thermostat Compatibility Checker. Most 24V HVAC systems are supported, including forced air, heat pump, and radiant systems.
⚠️ Note: Line voltage systems (120V or 240V) are not compatible.
🧰 Tools You’ll Need
- Screwdriver
- Smartphone with Alexa app
- Wi-Fi connection
- Access to your circuit breaker
🔌 Step 1: Turn Off Power to Your HVAC System
Go to your breaker panel and switch off the circuit for your heating and cooling system. This step is crucial for your safety during installation.
Confirm by adjusting the temperature on your old thermostat to make sure the system doesn’t turn on.
🧱 Step 2: Remove Your Old Thermostat
- Pull off the old thermostat’s faceplate.
- Label each wire according to the terminal it was connected to (e.g., Y, G, W, Rc, C).
- Disconnect the wires and remove the old mounting plate.
- Patch and paint if needed, or use the Amazon wall plate for a clean look.
⚙️ Step 3: Install the Mounting Plate
- Feed the labeled wires through the center opening of the Amazon Smart Thermostat’s wall plate.
- Use the provided screws to attach it to the wall.
- Ensure the plate is level before tightening.
🔧 Step 4: Connect the Wires
Match each wire to the corresponding terminal on the back of the thermostat. Push each wire into the terminal until it clicks.
If your system has a C-Wire, connect it to the “C” terminal. If not, use the C-Wire adapter included in the box and follow instructions from the Alexa app.
🖼️ Step 5: Attach the Thermostat
Snap the Amazon Smart Thermostat onto the wall plate. Once the wires are secure and power is restored, the screen should light up automatically.
If it doesn’t, double-check your wiring and ensure the breaker is turned back on.
📲 Step 6: Open the Alexa App and Add Device
Once the device is powered on:
- Open the Alexa app on your smartphone.
- Tap Devices > + > Add Device.
- Select Thermostat > Amazon.
- Follow the on-screen prompts to complete the setup.
The Alexa app will auto-detect the thermostat and guide you through connecting it to your Wi-Fi and HVAC system settings.
🗓️ Step 7: Set Up Schedules
After successful setup, you’ll be prompted to create custom heating and cooling schedules based on your lifestyle.
You can set temperatures for:
- Home
- Away
- Sleep
The thermostat uses geofencing and Alexa Hunches to auto-adjust your settings when you’re not home, helping you save on your energy bill.
🧠 Bonus: Enable Alexa Voice Control
Once connected, you can use Alexa voice commands like:
- “Alexa, set the thermostat to 72 degrees.”
- “Alexa, lower the temperature by 3 degrees.”
- “Alexa, what’s the thermostat set to?”
You can also control it remotely through the Alexa app or link it with Alexa Routines for automated temperature changes during your daily activities.
