A dual thermostat is a type of thermostat that allows you to control two separate heating and cooling systems in one space. This type of thermostat is often used in homes with multiple rooms, such as a two-story house, where different temperatures may be desired in different areas. With a dual thermostat, you can set different temperatures for each area, allowing you to maintain the perfect temperature in each room. This type of thermostat is also great for those who want to save energy, as it allows you to turn off the heating or cooling in one area while keeping it running in another. This helps to conserve energy and save money on your energy bills.
