Andover Continuum
Infinet II
i2887 Terminal Controllers
The Andover Continuum Infinet II (i2) 887 is a fully programmable,
low cost, general purpose terminal controller. It has all the
power of an Andover Continuum Infinet II controller, but with a
small form factor.

Terminal Controllers
Features
With its unique mix of three universal
inputs, one Smart Sensor/room sensor
input, four triac outputs and one relay
output, the i2887 can be easily configured
to control Heat Pumps, Fan Coils, or AC
units. Use the i2887 for direct control
of fans, staged heating and cooling and
monitoring of room temperature, outside
air temperature, return air temperature or
occupancy status.

Serviceability
• View and Mo dify In formatio n with Optional
Andover Continuum Smart Sensor Display
• Local On-Board Service Port
• Typical Applications:
- Fan Coil Unit
- Heat Pump
- Chilled Beams
The i2887 is compact so it can be installed in
tight locations with three mounting screws; and
its removable terminal connectors allow for easy
servicing.
While the standard i2887 version uses 24
VAC input power, the i2887-L model accepts
incoming line voltage at 115 or 230 VAC, has an
onboard transformer, and the same versatile I/O
configuration.
Similar to all i2 controllers, the i2887 features
Flash memory and a fast (32-bit) processor for
faster scan times, with plenty of additional memory
available for data logging of your critical data.
The i2887 communicates with the entire
Andover Continuum Infinet™ RS-485 field
bus; i.e., both Andover Continuum Infinet
and Andover Continuum Infinet II controllers,
and is compatible with Andover Continuum
CyberStation
254 Andover Continuum Infinet devices can be
networked to any Andover Continuum network
controller.

Increased Reliability with Flash Memory
The i2887’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 operating system via software downloads,
eliminating the need to swap out proms.
Inputs
The input configuration on the i2887 consists of
three full range Universal inputs that accept voltage
(0-5VDC), digital (on/off), counter signals (up to
4Hz), or temperature signals. The i2887 also offers
a fourth input to support the Andover Continuum
Smart Sensor, or any standard room temperature
sensor.

Outputs
The i2887 contains five digital outputs — four Form
A
Triac-based outputs plus one Form A Relay
output, capable of switching line voltage.
These outputs can be used separately for on/off or
pulsed control of lighting, heat, and fan units or can
be configured into Form K Tri-state outputs (2-max)
for bi-directional control of dampers and valves.
(Note: Any two consecutive Triac outputs can be
configured as a Form K output.) All Triac outputs
are ground referenced and rated for AC loads only.
Software Capabilities
The dynamic memory of the i2887 can be allocated
for any combination of programs, scheduling,
alarming, and data logging using the powerful
Andover Plain English
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 i2887 using the
Andover Continuum CyberStation. Programs are
then stored in, and executed by, the i2887.

Features
Programming multiple i2887s is inherently easy
with Plain English. A complete copy of one i2887’s
programs can be loaded directly into other i2887s
without changing any point names or programs.
In addition, channel assignments for the i2887 are
similar to other Andover Infinet devices such as the
i2851 for easy program conversion.

Smart Sensor Interface
The i2887 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.
