Advector Systems. The inVent damper and airflow register is now available in a wireless version. As part of the Select-Air System, inVent works with the Advisor 20-zone control system, Sub-Advisor wireless home automation thermostat, and Flex wireless remote temperature sensor. Using horizontal air distribution patterns, the wireless inVent is controlled by the Advisor and regulates the amount of conditioned air allowed into specific rooms based on user settings. Homeowners can reduce or eliminate conditioning of unused spaces for greater energy efficiency, the maker says. New construction and remodeling versions of the system are available. 817.416.4880. www.advectorsystems.com.
