A digital thermostat is an electronic device that regulates the temperature of a heating or cooling system in a home or building. Unlike traditional thermostats, which use a dial or lever, digital thermostats display the temperature on a digital screen and allow for precise temperature settings. They can be programmed to adjust the temperature at specific times, improving energy efficiency and comfort. Many digital thermostats also offer features like Wi-Fi connectivity, enabling users to control their heating and cooling systems remotely through a smartphone app. Some models are compatible with smart home systems, allowing for integration with other devices like smart speakers and home automation systems.
