Switching from a conventional thermostat to a programmable thermostat allows homeowners to save money on their energy bills as well as to maintain closer control of the temperature in their houses. As of 2015, the latest models are also programmable remotely through the Internet.
Programmable thermostats offer separate programs for different days of the week. Many of them issue alerts on their high-definition screen displays when they require maintenance. Some are equipped with portable controllers that allow a person to adjust settings from anywhere inside the building. Most people are capable of installing a programmable thermostat in under an hour.
Through Internet access, homeowners are permitted to check their home's HVAC performance and make adjustments with some programmable thermostat systems from a smartphone, tablet or PC. More sophisticated wireless control systems also offer remote control of music, lighting and window treatment motors.
Thanks to the energy efficiency of programmable thermostats, those who own them tend to enjoy several hundred dollars of savings on their electricity bills each year. As of 2015, several states are offering pilot programs that allow owners of programmable thermostats to access their electricity usage as well as the cost of their usage in live time, allowing them to modify their energy usage.
