SAFETY WARNING
Only qualified personnel should install and service the equipment. The installation, starting up, and servicing
of heating, ventilating, and air-conditioning equipment can be hazardous and requires specific knowledge and
training. Improperly installed, adjusted or altered equipment by an unqualified person could result in death or
serious injury. When working on the equipment, observe all precautions in the literature and on the tags,
stickers, and labels that are attached to the equipment.

Page 4: Overview
Overview The BACnet Communication Interface for ReliaTel (BCI-R) supports Trane ReliaTel rooftop units that function as part of a BACnet MS/TP communications network. It allows ReliaTel equipment to communicate with a building automation system (BAS) by using the BACnet protocol over an RS-485 MS/TP communications link. -

Getting Started Selecting Wireless Communication If using a wireless COMM interface (WCI), set the link select switch to IMC as shown in Figure For wiring instructions, refer to the “BACnet Communication Interface for ReliaTel Controllers” , RF-SVN03-EN. Figure 2. Wireless COMM Interface (WCI) BAS-SVP09B-EN... -
Page 7: Configuring The Bci-R
Configuring the BCI-R The BCI-R can be configured using either the Tracer™ BACnet Setup Tool or the Tracer™ TU service tool. Note: The BCI-R controller is fully configured from the factory for use with Tracer SC based systems. Additional configuration, or the use of Tracer TU, is not necessary. Additionally, the BCI-R self-configures itself to match the unit type upon initial power-up. - Page 8 Configuring the BCI-R To connect to Tracer TU: 1. Connect the USB cable directly from the laptop to the BCI-R, or to an equipment control panel USB port connected to the controller. Important: If using a PC with multiple USB ports, connect by using the same process outlined below for the same piece of equipment.

Page 9: Understanding The Mac Address And Bacnet Device Id
Understanding the MAC Address and BACnet Device ID MAC Address The MAC address is the rotary dial address. For Trane systems, this address must be between 1 and 127. Although “0,0,0, ” is a valid BACnet address, Trane reserves this address for the Tracer SC controller. - Page 10 Although 999 is possible from the dials, the maximum allowed number by BACnet is 127. The Max Master is not adjustable in Trane SC systems. For example, if the MAC address is 101 and the front-end system has a Max Master value of 100, the device will not be discovered.

Page 11: What To Do After Adding Options Or Equipment To The Unit
Configuring the BCI-R What To Do After Adding Options or Equipment to the Unit Restoring the BCI-R controller to factory defaults is necessary if the unit setup has changed after the initial self-configuration process. This process is called “clearing the controller” . For example, an economizer is added to the machine after the initial installation. -
Page 12: Managing Device Units On The Controller Units Screen
Configuring the BCI-R Managing Device Units on the Controller Units Screen The BCI-R device units can be viewed and managed on the Controller Units screen from either the BACnet Setup Tool or Tracer TU. When the BCI-R first powers up, or after the controller has been cleared, a list of points (the role document) is created from the information supplied to the BCI-R from the ReliaTel RTRM module through the Modbus link. -
Page 13: Bci-R Operation
To initiate system control: 1. Make binary output 1 (BO 1), system control command, active. Trane also recommends setting the relinquish default value to active when performing step 1. Note: BO 1 must in service in order to control from a BAS. -
Page 14: Periodic Update Of Bas Values
BCI-R Operation Periodic Update of BAS Values The BCI-R device requires the BAS system to provide a periodic update to the sensor values. This protects against a loss of communication between the BAS and the BCI-R. By BACnet definition, the present value of the object will maintain the last value written to it, regardless of the amount of time that has elapsed since the last write. -
