Get to know each other. Most people install the Nest Thermostat themselves in 30 minutes or less. Once it’s on your wall, it automatically activates the best features for your system and starts learning about you and your home. Teach Nest to save. Programming thermostats is complicated and irritating - but an un-programmed thermostat can waste 20% of your heating and cooling bill. So the Nest Thermostat programs itself. Just turn it up and turn it down. The Nest Thermostat learns what temperatures you like and builds a personalized schedule. Teach it efficient temperatures for a few days and, within a week, it'll start setting them on its own. Save while you’re away. With Auto-Away™, the Nest Thermostat automatically turns to an energy-efficient Away temperature when you’re gone. Auto-Away works in 90% of homes, even if your Nest is in a spot you don't pass on your way out the door. Nest on the go. Use the Nest app to connect to your thermostat from a phone. Getting in early? Change the temperature miles from home.
