Nest Learning Thermostat is the next generation of thermostats. It learns your schedule, programs itself and can be controlled from your phone. Programming thermostats is complicated and irritating - but an un-programmed thermostat can waste 20% of your heating and cooling bill. So the Nest Thermostat is easy to install and programs itself. It learns what temperatures you like and builds a personalized schedule. After teaching it efficient temperatures for a few days, it’ll start setting them on its own. It automatically turns to an energy-efficient temperature when you leave your home, and you can control it from your phone using Nest app. Adapting itself to your schedule and needs, Nest Thermostat can lower your heating and cooling bills up to 20%.
