Model Info

The Continuum b3885 VAV Controller is a native BACnet Advanced Application Controller (B-AAC) that communicates on an RS-485 field bus as Master devices using the MS/TP BACnet protocol.  The low-cost b3885 VAV Controller is equipped with a built-in actuator to streamline hardware installation and save commissioning time.  Two universal inputs, an airflow sensor, two Form A triac-based outputs, and an integrated damper actuator, make this controller perfect for smaller VAV applications.
