A Tale of Two Thermostats

Welcome to the next evolution of Sensi Wi-Fi thermostats

It was the best of times. And now it’s an even better of times. It is the age of intuitive design, convenience and integrated partnerships with names like Apple, Amazon and Wink. It is the age of accessibility, control and information. It is the age of trusting an established company like Emerson—with 125 years of experience in critical heating and cooling infrastructure systems—to meet your real needs. It is the season of a company that puts people over technology. It’s the season for purposeful innovation that fits seamlessly with your lifestyle. It’s the season of Sensi. Welcome to a new kind of home that keeps you connected to comfort.

We get it. Comfort is complicated. It’s personal. It’s shared. It’s physical. It’s emotional. And it’s entirely yours. Your house. Your rules. That’s why we have created two new Wi-Fi Thermostat options to work with your life—so you can always enjoy comfort on your terms. From easy installation to control from across the room or across the country, you’ll experience the comforts of home like never before.

The new Sensi™Touch Wi-Fi Thermostat—along with an updated version of the classic Sensi™ Wi-Fi Thermostat—are now compatible with Apple HomeKit™, bringing simple and secure control using the Apple Home app on iPhone, iPad or Apple Watch, or voice using Siri. (The new thermostats also work seamlessly with other smarthome platforms Amazon Alexa and Wink.)

Both new thermostats have settings and features you know and love like local weather information, indoor humidity sensors, auto changeover, fan control, Keypad Lockout and Smart Alerts to detect and alert you to critical conditions that could affect your family, your pets and your property. And the revamped Sensi mobile app will serve as your personal remote control, providing instant access to your thermostat via your smartphone.

Our latest Sensi thermostats combine support for Apple HomeKit with simple and secure controls, a sleek new interface and enhanced capabilities. For those living an unprogrammed life, we created the new Geofencing feature. By using your phone’s location relative to your individual thermostat’s location, we can automatically set your mode to home or away, creating a 3-degree offset to save you money while you’re gone. (Our current Sensi thermostat users can also use the new Geofencing feature.)

With two new thermostats to select, you may be wondering: What’s the difference?

The new Sensi Touch Wi-Fi Thermostat ST55 offers everything you love about our classic thermostat in a clean design to fit the modern home. Enjoy additional features like the bigger, easy-to-read high definition touch screen, a customizable home screen display and option to choose a continuous back glow for soft lighting in dark hallways or rooms. And for all those DIYers—we got you! The new Sensi Touch Wi-Fi Thermostat was designed with illuminated terminals for increased visibility while wiring and easy-click terminals that eliminate the need for a screwdriver.

Our updated Sensi Wi-Fi Thermostat ST55provides quick installation and control from anywhere via the intuitive mobile app. The Flexible Scheduling feature allows you to make a customized schedule that fits your routine—and any changes that come with it. It’s an easy way to save money without compromising your comfort.

In this age of smart technology and fast-paced living, you deserve a thermostat that gives you control, flexibility and confidence to enjoy the best of home comfort from anywhere. Explore all the features and find the Sensi thermostat that’s right for you.
