Here’s what you’ll need.
Download the Sensi app before you begin. This document is not meant to be used independently or to replace the step-by-step installation procedure found only in the Sensi app. The app is required for installation to ensure proper configuration and enable Wi-Fi control of your thermostat. The free Sensi mobile app is available on the App Store ™ and Google Play ™. Simply search for “Sensi” and download to your device to get started. All system types require a common wire (c-wire).
Installation Overview CREATE YOUR ACCOUNT. Open the Sensi app on your device and follow the prompts to create an account, using a valid email address. Your Sensi account can only be linked to one email address, but you can share your account information across devices so your whole family can have access. INSTALL YOUR THERMOSTAT. The Sensi app will walk you through removing your old thermostat from the wall, labeling your existing wires and installing your new Sensi thermostat. CONNECT TO WI-FI.
Installing Your Thermostat Turn off the power to your heating and air conditioning system by using your fuse box or the switch next to your furnace. WARNING: Confirm power is off before proceeding. To check, change the temperature on your thermostat. If your system turns on, it still has power.
REMOVE EXISTING THERMOSTAT COVER Remove the thermostat cover by using a screwdriver or by pushing the pressure latch. Some covers will detach easily, while others may need to be released with a screwdriver. WARNING: Do not remove your wires yet—this will be done in a later step.
TAKE A PHOTO OF YOUR WIRING Using your phone or digital camera, take a photo of your existing thermostat wiring in case you need to reference it later.
REMOVE ANY JUMPER WIRES If you see a jumper wire, remove it. Your new Sensi thermostat has the jumper wire built in. Leave all other wires connected to the thermostat.
LABEL YOUR WIRES Carefully label your wires by removing one wire at a time from the terminal and applying the corresponding wire label sticker to it. Your labels may not match - that’s okay! For example, if you have a W wire, you will apply a W/E sticker. Use the chart on the next page to find the correct wire label to use with each wire.
