From across the room or across the country, your Sensi Wi-Fi thermostat makes it easy to remotely control and schedule your home comfort - Anytime. Anywhere. Sensi thermostat does not require a common wire (c-wire) for most installations, so it is compatible with the HVAC equipment in many homes in U.S. & Canada. A c-wire is required for heat-only, cool-only and heat pump (without aux) systems, and for use with Apple HomeKit. Check to make sure it will work for you at sensi.emerson.com/compatibility. Put your comfort on your terms with geofencing or 7-day scheduling option with the ENERGY STAR certified Sensi thermostat. Both energy saving features you save about 23% on your HVAC energy usage, so you can save money without compromising your comfort. Energy savings calculated by comparing operation time for a nationwide sample of Sensi users with temperature adjustments averaging 4°F vs. users with no adjustments. Savings vary based on equipment type/condition, insulation, climate & temperature adjustment size/frequency. Based on survey results of 2120 respondents that purchased and installed a Sensi thermostat in 2018, approximately 70% reported installing in 30 minutes or less. Adding a common wire may impact installation time. Does not work with electric baseboard heat and some other systems. System requirements for mobile app: iOS - 10.0 or above Android - 4.2 or above (5.0 or greater to use the Geofencing feature).
