The Alerton BACtalk VAV-SDC3 controller is a versatile BACnet terminal unit device that provides pressure-independent control of any single-duct variable air volume (VAV) box. The VAV-SDC3 is part of Alerton's complete BACtalk product line in compliance with ANSI/ASHRAE Standard 135-1995, BACnet. As a native BACnet controller, it requires no proprietary chip sets to integrate seamlessly with your BACnet system, and communicates at up to 76.8 Kbps on a BACnet MS/TP LAN.
The VAV-SDC3 operates with the Alerton BACtalk Microset?äó, Microtouch?äó or wallplate sensors. The BACtalk Microset wall unit is an intelligent zone sensor with a digital display and simple push-button controls. It functions as both a tenant control center and field service tool, which enables a technician to view and change variables within the VAV-SDC3.
The BACtalk VAV-SDC3 contains an integral airflow sensor to provide pressure-independent operation of the VAV box. Each airflow sensor is factory-calibrated at multiple velocity points. Minimum, maximum and reheat airflows can be entered either at a Microset wall unit or a BACtalk for Windows operator terminal. A technician can adjust the calibration in the field during balancing to compensate for slight variations in box installation and type.
All control algorithms are factory-loaded into EEPROM and can be field-modified. The VAV-SDC3 can execute control algorithms independently of other equipment. All calibration, programming and operatorentered setup data is stored in non-volatile EEPROM for further assurance of stable, reliable and independent operation.
The BACtalk VAV-SDC3 is your complete answer to control of all single-duct VAV boxes in a BACnet environment. With integral flow sensor and programming flexibility, the VAV-SDC3 provides every option for precision VAV box control.. Alerton. Honeywell. VAV-SDC3.
