The Variable Air Volume Box (VAV) Controller is specifically designed for digital control of single duct, dual duct, fan-powered, andsupply/exhaust VAV box configurations. The controller can provide standalone control of the VAV box, and can also integrate control of baseboard heat and lighting logic for the room or zone. An optional user-to-controller interface, called the Zone Terminal (ZT), provides easy controller adjustment and indication. The ZT also offers weekly and
holiday scheduling for standalone systems, as well as password protection for the VAV Controller.
