Congrats, you have purchased a new Emerson Sensi Smart Thermostat! It's time to set it up with the help of the info and videos below.

First and Foremost, is it Compatible with Your HVAC System?

The Sensi Smart thermostat is compatible with most HVAC systems, but not all. If you didn’t check compatibility prior to purchasing your new Sensi, don’t tear into that box just yet.

Use the Sensi Compatibility Checker.

Does a Sensi Smart Thermosat Require a C-Wire?

Though the Sensi Smart Thermostat is Wi-Fi enabled, it does not necessarily require a C-wire to function. It depends on your HVAC system. A C-wire is required for heat only systems, cool only systems, and heat pump systems.  It is also required for pairing with Apple HomeKit.
