ActronAir NEXUS Touch Controller Kit provides intuitive touch screen control of ActronAir UltraSlim Ducted systems, with a 7-inch high-resolution touch screen, on-board temperature and humidity sensors, Over-The-Air Wi-Fi updates, and compatibility with the NEXUS Zone Control Box for management of up to 16 zone dampers. Built-in speaker and easy-to-use interface simplify daily operation for homeowners and facilities managers. Low voltage inputs only — connecting 240VAC will damage equipment and void your ActronAir warranty.
