Overview
The BACnet® Communication Interface for Chillers
(BCI2-C) is comprised of a Trane controller with interface
software. It is a non-programmable communications module
that allows heating, ventilation, and air-conditioning (HVAC)
equipment to communicate on a BACnet communications
network.
This guide provides information about:
• BACnet protocol
• Specification, requirements, and dimensions
• Installing the BCI2-C in the chiller control panel
• Mounting and removing/reposition the BCI2-C
• Mounting a CGAM slant BCI2-C
• Setting rotary switches for the BCI2-C
• Connecting and configuring the BCI2-C with Tracer TU
software
• Configuring a CH530 for BACnet with TechView™ service
software
Note: The TechView functionality described in this
document is the same functionality as described in
the KestrelView™ documentation.

BACnet Protocol
The Building Automation and Control Network (BACnet and
ANSI/ASHRAE Standard 135-2004) protocol is a standard that
allows building automation systems or components from
different manufacturers to share information and control
functions. BACnet provides building owners the capability to
connect various types of building control systems or
subsystems together for a variety of reasons. In addition,
multiple vendors can use this protocol to share information for
monitoring and supervisory control between systems and
devices in a multi-vendor interconnected system.
The BACnet protocol identifies standard objects (data points)
called BACnet objects. Each object has a defined list of
properties that provide information about that object. BACnet
also defines a number of standard application services that are
used to access data and manipulate these objects and
provides a client/server communication between devices. For
more information on BACnet protocol, refer to “Additional
Resources,” p. 20.
BACnet Testing Laboratory (BTL) Certification
The BCI2-I supports the BACnet communication protocol and
has been designed to meet the requirements of the BACnet
Building Controller (B-BC) profile. For more details, refer to the
BTL web site at www.bacnetinternational.org.
