•BTL Listed B-AAC Controller with Local Trends

The b3865 and b3866 are unique, lowcost 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 triacbased outputs; and an integrated damper actuator, make these controllers perfect for VAV applications requiring reheat control. Both models feature a room sensor input, which supports Andover Continuum Smart Sensor, or any standard room temperature sensor.

•The b3866 model is identical to the b3865, with the exception that it also offers two analog outputs to control reheat valves, lighting ballast control, etc.

•The b3865/866 features Flash memory, increased user memory, and a fast (32-bit) processor for faster scan times, with plenty of additional memory available for data logging of your critical data.

As native BACnet controllers, the b3865/866 can communicate with other BACnet devices on the MS/TP network, in strict accordance with ANSI/

ASHRAE standard 135-2004, and are listed with the BACnet Testing Labs (BTL) as BACnet Advanced Application Controllers (B-AAC). By connecting

to the Andover Continuum bCX1 or b4920, the b3865/866 or other MS/TP devices can share and gather data from the wider Ethernet/IP network

of controllers. Among those Ethernet controllers can be Andover Continuum controllers (BACnet or Andover Continuum Infinet) or third-party BACnet

IP devices. All Andover devices, both BACnet and

Andover Continuum Infinet, are fully compatible with the Andover Continuum CyberStation front-end software, a fully native BACnet Operator Workstation (B-OWS) application.
