Meet the 3rd-gen Nest Learning Thermostat. It has new rings and a big, sharp display. And it saves energy. That’s the most beautiful part. The Nest Learning Thermostat automatically adapts as your life and the seasons change. Just use it for a week and it programs itself. Nest shows you how much energy you use every day in Energy History and every month in your Home Report. It’s easy to install the Nest Learning Thermostat. Everything you need comes in the box.
