Installation Guide
Once you have downloaded the Sensi app, and have created an account, you are ready to install the thermostat to your wall and connect it to Wi-Fi. If no thermostats are registered yet, tap the plus (+) sign to add a thermostat.
First, choose which thermostat you purchased. The Sensi Lite smart thermostat option is for the following model numbers:
Note: You can check your model number on the back of the thermostat cover.
The app will ask you if this is a new installation or if you just need to connect to Wi-Fi.
If you answered “Connect to Wi-Fi,” please jump to Step 6 for instructions.
If you answered, “New Installation,” please continue to walk through the installation instructions.
Turn off the power to your heating and air conditioning system before handling your thermostat wires.
Next, remove the old thermostat cover using a screwdriver, by pushing the pressure latch, or simply pulling the cover off. The Sensi app will prompt you to take a picture of your existing thermostat and old wiring in case you need it later. This can be helpful for troubleshooting with our technical support team if necessary. The picture you take will be saved to your camera roll or photo gallery.
Then, throw away any jumper wires. Sensi thermostats have a jumper wire built into them, and you will not need any jumper wires from your old unit.
Next, choose the terminal labels that have wires attached to them on your old thermostat. The app will tell you if you have a valid configuration. If you are getting an invalid configuration message, you can learn more about compatibility. Sensi Touch 2 smart thermostats require a c-wire.
After choosing the terminal labels, select what type of system you have, then label your wires. Using the provided wire label stickers, label your wires by removing one wire at a time. After all your wires are labeled, remove the old thermostat base from the wall.
Use the provided mounting screws and secure the Sensi thermostat base to the wall.
Once the Sensi thermostat base is mounted and secured on the wall, insert the wires into the corresponding terminals and use a screwdriver to secure each wire.
On the back of the thermostat or in the Get Started insert found in the box, you will find the QR code to connect the thermostat to your Wi-Fi network. Scan this code. You will need to allow Sensi access to Bluetooth to connect properly.
if you're having trouble scanning, tap the use PIN to manually enter the code located under the QR code.
Next, install the two provided AAA batteries and push the thermostat cover onto the base.
Then, turn your power back on.
On the thermostat, press and hold the Mode button for four seconds. You will the setup and Wi-Fi icons appear.
In the mobile app, select your home Wi-Fi network and then enter your home Wi-Fi network password.
Next, you can select a name and or choose a custom name for your thermostat. Press "Next" to continue. After successfully connecting your Sensi thermostat, the app will prompt you to register the thermostat. You can either choose the "Locate Me" option or fill in your street address, city, state, zip code, country, and time zone manually. Press "Next" to continue.
Congratulations on successfully installing your Sensi thermostat. Press “Start Using Sensi Thermostat” to open the main screen on the app.
