A smart thermostat is a wi-fi connected device that may be controlled using a phone, tablet or other wi-fi connected device. Some smart thermostats are capable of automatically adjusting heating and cooling for optimal performance.
Space heating and cooling make up almost two-thirds of home energy use. Switching to a smart thermostat can lower energy use by 8-12% which can improve home comfort and overall efficiency. Some units are capable of learning your living patterns, adjusting while you are away, and providing data to help you adjust the schedule.
Note: Before purchasing a smart thermostat, ensure that your current wiring is compatible with the new system. Most smart thermostats require a C wire or Common Wire connection to provide constant power to the system.
