Thermostats & Controls

Home Automation

The Côr™ thermostat automatically downloads the latest software, so its features are always up-to-date. That includes easy-to-read energy reports that help you make the connection between thermostat settings, weather changes and your energy bills. You’ll also receive customized tips to help you save even more.


Take control of your home comfort with a fingertip or just let the Cor™ thermostat do the work for you. Homeowners saved an average of 20% on their heating and cooling energy costs* with features like smart recovery, a function that intelligently adapts beyond manual programming for greater efficiency.
