Introduction
Amazon Smart Thermostat doesn't have a speaker or microphone. For voice control, use a compatible
Alexa-enabled device, like an Echo (sold separately), or the Alexa app. Before purchasing, use the link
“check compatibility” to see if the thermostat will work in your home and to determine if your home
needs a C-wire power adapter. Amazon Smart Thermostat requires a C-wire or a power adapter kit. Use
the compatibility checker to see if your home has one already. Guided installation instructions are
included in the Alexa app.

Getting Started
Set Up Your Amazon Smart Thermostat
Guided, illustrated directions in the Alexa app help you install and set up your Smart Thermostat.
On your mobile device, open the Alexa app
Open More and select Add a Device .
Under All Devices, select Thermostat .
Under What brand is your thermostat?, select Amazon.
Under Has your thermostat already been installed on the wall?:
● Select No for guided instruction in the app on how to connect the wiring and install your
Thermostat.
● Select Yes for instruction in the app on how to connect your Thermostat to Wi-Fi and to
Alexa.
Connect the Wiring for Your Amazon Smart Thermostat
We recommend that you use the guided instructions in the Alexa app to help you install your Amazon
Smart Thermostat. See how to get started in the Alexa app at Set Up Your Amazon Smart Thermostat. If
you don’t have access to the Alexa app, the steps below are part of those instructions.
If you are not comfortable working with electrical wiring or your home heating and cooling system,
contact a HVAC service company to install and set up your Thermostat.
Remove the faceplate or box from your old thermostat. Before disconnecting any wires, take a picture of
the wiring connections for later reference.
Look for any of the following indicators that your system is high-voltage:
● Warning labels that say 110v or 220v
● Wires labeled L1 or L2
● Wires connected by wire nuts (screw-on caps)
● If you see any of those high voltage indicators, the Amazon Smart Thermostat won’t work with your
system
● Make careful notes of which terminals have wires connected. Take a photo with your phone for
reference, including the terminal labels.
● Remove one wire at a time. Use the stickers that came with your Amazon Smart Thermostat to
label each wire with the terminal it came from. Repeat until all wires have been removed and
labeled. Don’t let the labeled wires fall back into the wall.
● Make sure there is a wire for the C terminal, which provides power from the HVAC system to the
Thermostat. If you have no wire for the C terminal, some newer homes might have an unused wire
behind the wall plate. If there is no unused wire to convert to a C wire, a C-Wire Adapter is
required. We recommend the adapter compatible with the Amazon Smart Thermostat.
● If you find an unused wire, label it with the C sticker, and connect the other end of that wire at your
HVAC system’s control panel to the C terminal, sometimes labeled as “24V” or “24 common”. Then
connect the end at the Thermostat to the C terminal.
● Remove the wall plate from your old Thermostat. Install the Amazon Smart Thermostat optional
trim plate if you want, and then install its wall plate so the labeled wires can come through.
● When the wall plate is fastened to the wall, connect each labeled wire from the wall into the slot as
directed in the Alexa app. Refer to the labels, and the picture you took if needed. After connecting,
gently tug each wire to make sure they’re connected. Make sure the R terminal switch is in the up
position.
● Close the wire cover on the wall plate. Then align the Amazon Smart Thermostat faceplate with the
wall plate and press together gently until it clicks into place.
● Turn the heating/cooling system power back on at the breaker box or switch where you turned it
off.
How to Control Your Amazon Smart Thermostat by Voice
Use any Echo device connected to your network to set or adjust the temperature.
Try these voice commands, using a connected Echo device or the Alexa app on your mobile
