NEST Learning Thermostat - 3rd Generation
The Nest Learning Thermostat learns the temperatures that you like when you’re at home and then programs itself. It turns itself down when you’re away. That’s how it saves energy. And here’s the proof.
Most thermostats are programmable. They make you enter every temperature change that you want throughout the day or choose a start and stop time for heating your home. It’s annoying and complicated – many people don’t even bother.
