b3865/866/885-V VAV
Controllers with Built-in Actuator

The Andover ContinuumTM b3865-V, b3866-V and b3885-V are
native BACnet controllers that communicate on an RS-485 field
bus as Master devices using the MS/TP BACnet protocol.

BACnet b3865/866/885-V VAV Controllers
with Built-in Actuator
Features

The controllers are highly intelligent,
low-cost VAV box controllers that come
equipped with a built-in actuator to
streamline hardware installation and save
commissioning time. Universal inputs, an
airflow sensor, Form A triac-based outputs,
and an integrated damper actuator
make these controllers perfect for VAV
applications. The b3865/866-V models
feature a room sensor input, which supports
our Andover Continuum Smart Sensor, or
any standard room temperature sensor.

Bus communications

•

The b3865-V is the base model with four universal
inputs, an airflow sensor, three Form A triac-based
outputs, and an integrated damper actuator.

• The b3866-V model is identical to the b3865-V,
with the exception that it also offers damper
position feedback and two analog outputs to
control reheat valves, lighting ballasts, etc.

• The b3885-V has a reduced I/O point count for
smaller VAV applications.

• All VAV models feature Flash memory, user
memory for programs, and a fast (32-bit)
processor for faster can times, with plenty of
additional memory available for data logging of
your critical data.
