Model Info

The Continuum b3865 and b3866 are native BACnet Advanced Application Controllers (B-AAC) that communicate on an RS-485 field bus as Master devices using the MS/TP BACnet protocol.  The b3865 and b3866 are unique, low-cost VAV box controllers that come equipped with a built-in actuator to streamline hardware installation and save commissioning time.  Four universal inputs; an airflow sensor; three Form A triac-based outputs; and an integrated damper actuator, make these controllers perfect for VAV applications requiring reheat control.
