The Alerton VisualLogic VAV-SD2A-E is a versatile, BACnetcompliant field controller that provides pressure-independent control of any single-duct variable air volume (VAV) box. It is particularly suited for controlling VAV series fan boxes equipped with a variable speed fan. As a native BACnet controller, the VAV-SD2A-E integrates seamlessly with your BACnet system, communicating at up to 115.2 Kbps on a BACnet MS/TP LAN. The VAV-SD2A-E-F includes a filter to reduce dust contamination. The VAV-SD2A-E eliminates the need for expensive products and external pressure sensors to control VAV boxes equipped with variable speed fans or analog valves. It features two analog outputs, auto-selectable as either 0-10V or 0-20mA, to control either a variable speed fan, an analog heating valve, or another analog device. The VAV-SD2A-E supports the Alerton Microtouch, as well as the BACtalk Microset, Microset II, and Microset 4 intelligent wall sensors, which offer convenient data display, setpoint adjustment, and technician access to equipment setup parameters. All VAV-SD2A -E control logic is programmed using Alerton's easy-tolearn graphical programming language, VisualLogic. Programming and setup data are stored in non-volatile flash memory, ensuring stable and reliable operation.The VAV-SD2A-E contains an integral airflow sensor to provide pressure independent operation of the VAV box. The airflow sensor is factory calibrated at multiple velocity points and is field-adjustable during balancing. Minimum, maximum, and reheat airflows can be entered using a Microset wall unit or compatible operator workstation software.
