There are three rotary switches on the front of the BCI-C device that are used to define a three-digit address when the BCI-C is installed on a BACnet communications network.

For more details, refer to the BTL web site at 6 BAS-SVP05D-EN BCI-C Integration Guideħ Rotary Switches and LEDs Rotary Switches This section provides information about the BCI-C rotary switches and LED displays. BACnet Testing Laboratory (BTL) Certification The BCI-C supports the BACnet communication protocol and has been designed to meet the requirements of the application-specific control profile. For more information on BACnet protocol, refer to Additional Resources, p. 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. Each object has a defined list of properties that provide information about that object. The BACnet protocol identifies standard objects (data points) called BACnet objects. 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. BACnet provides building owners the capability to connect various types of building control systems or subsystems together for a variety of reasons. BACnet Protocol The Building Automation and Control Network (BACnet and ANSI/ASHRAE Standard ) protocol is a standard that allows building automation systems or components from different manufacturers to share information and control functions. For more detailed information about this protocol, visit the company web site listed under Additional Resources, p. This guide provides: A brief overview of the BACnet protocol A explanation of the BCI-C device rotary switches and LEDs Data point configuration property definitions Tables listing object data points Additional resources A glossary of terms Note: Users of this guide should have basic knowledge of BACnet protocol.

It is a non-programmable communications module that allows heating, ventilation, and air-conditioning (HVAC) equipment to communicate on a BACnet communications network. 2 BAS-SVP05D-EN BCI-C Integration Guideģ BAS-SVP05D-EN BCI-C Integration Guide 3Ĥ Table of Contents Overview BACnet Protocol Rotary Switches and LEDs Rotary Switches LEDs Description, Behavior, and Troubleshooting BACnet Data Points and Configuration Property Definitions BACnet Protocol Implementation Conformance Statement (PICS) Standardized Device Profile (Annex L) Interoperability Building Blocks (Annex K) Segmentation Capability Object Types BACnet Protocol Data Link Layer Options Device Address Binding Networking Options Character Sets Object Data Points and Diagnostic Data Points with Corresponding Chiller Models BCI-C Alarming Additional Resources Glossary BAS-SVP05D-EN BCI-C Integration Guideĥ BAS-SVP05D-EN BCI-C Integration Guide 5Ħ Overview The BACnet Communication Interface for Chillers (BCI-C) is comprised of a Tracer UC400 controller with interface software.
