Chapter 1  
Overview  
The Tracker building automation system (BAS) is an energy management  
system for small- to medium-size buildings. The Tracker BAS controls  
heating, ventilating, and air conditioning (HVAC) equipment. It consists  
of a Tracker controller (Figure 1) and an optional PC workstation.  
The Tracker BAS can be operated by using either a Tracker controller or a  
PC workstation that is running Tracker PC Workstation software. A  
visual interface enables an operator to set up and change HVAC  
operating parameters and to collect and display building information.  
The Tracker PC Workstation software allows a PC to be connected to the  
Tracker controller directly with a prescribed adapter and cable, locally  
over a standard Ethernet local area network (LAN) connection, or  
remotely with a modem and standard phone line.  
The Tracker BAS supports Comm5 communications architecture, which  
is the Trane implementation of LonTalk® protocol. It resides on a network  
(Figure 2 on page 2 and Figure 3 on page 3) that includes HVAC and  
other comfort-related equipment, such as Trane VariTrac zoning systems;  
zoning controls; unit control modules (UCMs), which control and monitor  
other HVAC equipment; Tracer LCI-V (LonTalk® communication  
interfaces for Voyager rooftop controls); Tracer LCI-R (LonTalk®  
communication interfaces for ReliaTel rooftop controls); external input/  
output (I/O) devices, which help to monitor and control specific areas or  
devices; and miscellaneous equipment such as sensors, lights, and fans.

Controller components  
The controller consists of a termination module, main module, and  
display module (Figure 4).

Controller components  
Termination module  
The termination module (Figure 5) is a housing that provides a  
termination board and cable access for power, communications, and  
system input connections. Mounting holes enable it to be mounted on a  
wall or a recessed conduit box. The termination board accepts connections  
for power, communications, and system inputs.

Chapter 1 Overview  
Main module  
The main module (Figure 6) is a housing that contains the main logic  
board and the Ethernet board. The main module can be “hot swapped”: it  
can be removed and installed without removing power from the  
termination module. When the main module is installed onto a powered  
termination module, it receives power and begins to operate  
automatically.  
The main logic board provides an Ethernet LAN port, a PC interface port,  
and a modem port. It provides an internal interface to termination  
module I/O. It also provides Comm5 communication, 24 VAC power,  
alarm, and communication indicators. It communicates and exchanges  
data with the devices wired to the termination module. It also  
communicates with the display module.  
The Ethernet board provides two LED indicators. One shows that an  
Ethernet link is detected; the other shows that there is serial traffic  
between the Ethernet board and the main logic board.

Controller components  
Display module  
The display module (Figure 7) is a housing that contains a printed circuit  
board, liquid crystal display (LCD) touch screen, and an alarm LED. The  
printed circuit board supports the LCD touch screen and the alarm LED.  
The touch screen provides the operator access to the user interface  
program.  
The display module can be “hot swapped:” it can be removed and installed  
without removing power from the main module. When the display module  
is installed onto a powered main module, it receives power and begins to  
operate automatically.

Chapter 1 Overview  
UCM maximum capacities for Tracker  
models 12 and 24  
The Tracker model 12 and 24 controllers can control and monitor specific  
types and numbers of Trane unit control modules (UCMs) as specified in  
this topic. The supported UCMs are as follows:  
•
HVAC controllers that conform to the LonMark® Space Comfort Con-  
troller (SCC) profile: the primary controller options are the Voyager  
rooftop with a Tracer LCI-V, Precedent rooftop with ReliaTel controls  
and a Tracer LCI-R, and Tracer ZN517 unitary controller. Other con-  
trollers are limited to the Tracer ZN510, ZN511, and ZN524.  
•
•
VariTrac central control panels (CCPs) with a TCI-V.  
Tracer MP503 I/O module.  
Table 2 shows the maximum number of each UCM type that can be linked  
to each Tracker controller model. Any combination of the specified UCMs  
may be used in aggregate if they do not exceed the maximum. (For  
example: A fully loaded Tracker 24 controller can control 24 SCC devices,  
10 VariTrac CCPs, and 4 Tracer MP503 I/O modules.)  
The Trane VariTrac CCP is the main controller for either a changeover  
bypass system configuration or a delivered variable air volume (VAV)  
system configuration. Any combination of CCP configurations may be  
used in aggregate, as long as they do not exceed the maximum.  
Note:  
•
•
•
Each VariTrac CCP configured for changeover bypass can  
control 1 HVAC device and up to 24 VAV UCMs.  
Each VariTrac CCP configured for delivered VAV can con-  
trol 1 HVAC device and up to 32 VAV UCMs.  
See repeater information, “Requirements for repeaters on  
Comm5 communication links” on page 37.
