Features


In a home, zoning lets people maintain comfortable temperatures in rooms where they spend most of their time, and it minimizes heating and cooling to areas infrequently used. Consumers enjoy optimal room temperatures, and zoning pays for itself through reduced energy costs and the installation of multiple systems. In commercial applications such as an office, a conference room can be kept at a cooler temperature than the rest of the facility. A restaurant dining area could be kept at a different temperature from the kitchen or any offices. Everyone benefits from zoning, and it’s suitable for a wide range of applications.
