The 3rd-generation Nest Learning Thermostat is slim, sleek and beautiful. With a big, sharp display and Farsight, you can see the temperature, time or weather from across the room. The Nest Thermostat learns the temperature you like, then programs itself. It knows how long it takes to heat your home so that you’re comfortable when you get there. When you leave, it turns itself down so that you save energy. And with the Nest app you can change the temperature or check your Energy History from anywhere.
