Choose the b3810 model with the
confi guration that matches your
application:

• The b3810, designed for stand-alone equipment
control of Roof Top Units, Air Handling Units, or
other packaged mechanical equipment, features
eight universal inputs, one Smart Sensor/Room

Sensor input, plus eight program-controlled
digital outputs.

• The b3814, designed for stand-alone equipment
control of Roof Top Units, Air Handling Units, or
other packaged mechanical equipment, features
eight universal inputs, one Smart Sensor/Room
Sensor input, plus four program-controlled digital
outputs and four analog outputs for direct control
of devices requiring 0-10 volt control signals.

Both models feature an additional room sensor

input, which supports Andover Continuum Smart
Sensor, or any standard room temperature sensor.

The b3810 series also features universal inputs, a

real-time clock, override switches on all outputs,
two-piece removable connectors, and the ability to

expand the I/O for additional points.

The b3810 Series also features Flash memory,
increased user memory, and a fast (32-bit) processor
for faster scan times, with plenty of memory available
for data logging of your critical data.

As native BACnet controllers, the b3810 Series

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 an Andover Continuum b4920
device or bCX1 network controller, the b3810

series and other MS/TP devices can share data

from the wider Ethernet/IP network of controllers.

Increased Reliability with Flash Memory

The b3810’s non-volatile Flash memory stores your

operating system and application programs, so

that in the event of a power loss, your application

will be restored when power is returned. In

addition, the Flash memory allows for easy
upgrades of your

downloads, eliminating

proms. The b3810 controllers include an on­board battery to safeguard your runtime data —
protecting all point data and log data from being
lost if power is removed.

Inputs

The input conguration on the b3810 series
consists of eight full range, 12-bit Universal inputs
that accept voltage (0-10VDC), digital (on/off),
counter signals (up to 4Hz), temperature signals, or
supervised alarm circuits for security applications
or broken wire detection. The b3810 Series
offers an additional input to support the Andover

Continuum Smart Sensor, or any standard room
temperature sensor.

Outputs

The b3810 contains eight Form C relay outputs,
each rated for 24 VAC/30VDC, 3 amp, while the
b3814 contains four Form C relay outputs and four
analog outputs (0-10V). Both the relay and analog

outputs have manual override switches, with

software feedback of the switch position.

The b3810 contains an I/O expansion port for
the addition of up to two Andover Continuum xP
expansion modules directly on the bottom of the
controller. The xP family of modules includes the
xPDI8, xPUI4, xPDO2, xPDO4, xPAO2, xPAO4.

In addition to two input/output modules, the I/O

bus supports the xP Local Display Module, which

allows the user to view and change point values.

Software Capabilities

The dynamic memory of the b3810 can be
allocated for any combination of programs,

scheduling, alarming, and data logging using the

powerful Andover Plain English programming
language. Our object-oriented Plain English

language with intuitive keywords provides an easy
method to tailor the controller to meet your exact

requirements. Programs are entered into the b3810

using the Andover Continuum CyberStation
Programs are then stored and executed by the

b3810 controllers.

Programming multiple b3810 Series controllers is
inherently easy with Plain English. A complete copy
of one b3810’s programs can be loaded directly
into other b3810s without changing any point

names or programs.

Smart Sensor Interface

The b3810 provides a built-in connection for

Andover Continuum Smart Sensor. The Smart

Sensor provides a 2-character LED display and

a 6-button programmable keypad that enables
operators and occupants to change setpoints,

balance VAV boxes, monitor occupancy status, and
turn equipment on and off. An enhanced version
of the Smart Sensor is also available with a 4-digit
custom LCD that provides the following icons: PM,

%, °, Setpoint, Cool, Heat, CFM, Fan, OA, and SP.

Local Display

The local display with keypad (xP Display) allows for
the addition of a fully programmable local display
module that can be mounted within 10 feet (3
meters) of the controller. Connected via a ribbon
cable, the xP-Display easily allows the Operator
Interface to be mounted on the door of an enclosure

or on a wall below or next to the controller.

Optional Wireless Internet

The b3810 Series BACnet controllers can also

communicate using a wireless mesh network. Simply
plug Andover Continuum Wireless Adapters into

the service ports of these controllers with wireless

compatible firmware to create a wireless mesh
network that sends and receives BACnet messages.
