Trane SensorsControlling the comfort in abuilding space begins with Tranesensors. We designed our sensorsfor use with Trane Tracer systemsto provide the accuracy andrepeatability required by DDCcontrol. Trane sensors arecompatible with a variety of Tranebuilding level and unit levelcontrollers. In addition, thesensors are architecturallycompatible with each other andwith modern building interiors.

Sensor CapabilitiesTrane room temperature sensorsare available in several variations,and include options for setpointadjustment and override switches.Use Trane room humidity sensorsto control humidifiers anddehumidification equipment.Controlling building humidity is animportant element in maintainingindoor air quality. Trane also offersfield-applied sensors to measurepressure, temperature, andhumidity in air and waterapplications.

CO2 Sensor CapabilitiesCarbon dioxide is present in the airin variable amounts and can bemeasured in parts per million(PPM) by the Trane CarbonDioxide (CO2) Sensor. Elevatedconcentrations of carbon dioxidein a building zone can indicate aspace is occupied above designconditions, or that there is a

problem or deficiency with thebuilding’s ventilation system.

When connected to a Tracerbuilding management system andthe appropriate ventilationequipment, the Trane CO2 Sensorprovides building designers,operators, and owners a practicaland affordable means to respond toconcerns of indoor air quality andoccupant comfort.

Typical applications for the CO2Sensor include:

• Monitoring and recording CO2

levels in occupied buildingspaces

• Identifying underventilated

building zones

• Overriding outdoor air flow

beyond design ventilation rates ifCO2 exceeds an acceptable level

• Using CO2 measurement toidentify changes in occupancy

of a space

Simple Building Control

Programmable Control ModuleA Programmable Control Module(PCM) provides direct digitalcontrol and monitoring for a widerange of HVAC and otherapplications. Typical uses includecontrolling air handling equipment,interfacing with water chillingunits and boiler systems, andcontrolling pumps and coolingtowers.

ICS CapabilityThe PCM extends the Trane ICStechnology to existing, auxiliary,and non-Trane equipment. A PCMcommunicates with a Tracerbuilding control system over asingle communication link.

Software CapabilitiesThe PCM has the flexibility toprovide custom standalone controlsequences using Process ControlLanguage (PCL). The PCL routinesare programmable and can performlogical and mathematicalcalculations.

The PCM also provides directdigital control (DDC) loops, whichare separate software modules,enabling proportional, integral, andderivative (PID) control of

modulating devices. The operatorcan define PID gains along withhigh and low output limits. ThePCL routines and DDC loops canexecute as frequently as once everyfive seconds.

Both the PCL and DDC softwareprovide special testing capabilitiesfor the custom control sequences.Each PCL routine can be manuallyexecuted, one statement at a time,in a special test mode to allow theoperator to verify the programlogic. The performance of eachDDC loop can be graphicallyplotted to assist the operator intuning the loop.

PCM programs are written andcompiled on a PC using PCM Editsoftware.

This software also allows theoperator to access the PCM toperform the following functions:

• Modify parameters

• Edit the display setup

• View input/output status

• Use the PCL test function

• Plot DDC loops

• Manually control the PCMoutputs

Hardware DescriptionThree versions of the PCM areavailable:

• Standard ambient:NEMA Type 1 metal enclosure(32 to 120°F, 0 to 49°C)

• Extended ambient:NEMA Type 1 metal enclosure(-40 to 158°F, -40 to 70°C)

• Weatherproof:NEMA Type 4 metal enclosuresuitable for outdoor use(-40 to 158°F, -40 to 70°C)

An optional display and keypadinclude a 2-line by 20-characterLCD that can display up to 32status and control points.

For more information about the PCM, refer toTrane publication BAS-TS-43.

Universal ProgrammableControl ModuleThe Universal ProgrammableControl Module, or Universal PCM,is a programmable, direct digitalcontroller that provides controland monitoring for a wide range ofequipment. Typical uses includecontrolling air handling units,monitoring chiller plants includingpumps and cooling towers, andserving as a central point gatheringpanel.

ICS CapabilityAs part of the ICS family and as anextension of the existing PCM, theUniversal PCM provides flexible,independent control for a variety ofapplications. Because of itsflexibility, the Universal PCM canprovide control of both Trane andnon-Trane products. The UniversalPCM communicates with the Tracer


General-Purpose Unit ControlGeneral-purpose controllersprovide the capability to tie Traneequipment without unit controlmodules and non-Trane equipmentinto the Trane communicationnetwork. Products include theThermostat Control Module,Programmable Control Module, andthe Universal ProgrammableControl Module.

Thermostat Control ModuleThe Thermostat Control Module(TCM) provides a basic yetpowerful interface between TracerSummit, Tracer 100 series, orTracker systems and mechanicalequipment.

The TCM can extend the IntegratedComfort system (ICS) technologyto existing, auxiliary, and non-Traneequipment. The TCMcommunicates with a buildingcontroller over a singlecommunication link.

ICS CapabilityThe TCM provides an interfacebetween the building control paneland equipment not having TraneUnit Control Modules (UCMs), suchas lighting, fans, and non-Traneunitary equipment normallyoperated by a standard thermostat.

Software CapabilitiesThe TCM can function either as a 2-stage heat/2-stage cool thermostatfor air conditioning units and heatpumps, or as a provider of slavepoints for the buildingmanagement panel.

In thermostat mode, the TCMmonitors its sensors and controlsits outputs like a wall thermostat.The TCM can be configured aseither a 2-stage heat/2-stage cool airconditioning thermostat or a heatpump thermostat. This controlresides in the TCM, and the TCMcan operate standalone (withoutthe building management panel)during system startup or whenthere is a communication loss.

In slave mode, the buildingcontroller monitors the TCM inputsand directly controls the TCMoutputs. The TCM input andoutput points function as thoughthey are hardwired, generic pointson the building control panel.

The building control panelprovides control such as time ofday scheduling and demandlimiting.

See the appropriate BuildingControl section of this catalog fordetails on each panel’s capabilities.

Hardware DescriptionThree versions of the TCM areavailable:

• Standard ambient:Resin enclosure (32 to 120°F, 0 to49°C)

The system can provide multipleOn/Off time periods per day foreach of the seven weekdays. It alsocan provide:

• Holiday schedules and multipleholiday dates

• Exception day schedules

• Automatic daylight saving time

• Optimal start by group

Setpoint Control

The system allows the operator tocontrol setpoints for all VariTraczone UCMs. Setpoint controlincludes occupied and unoccupiedheating and cooling setpoints, andair volume minimum andmaximum setpoints. If desired, usea setpoint control mounted on thezone sensor. The setpoint knob canbe enabled and disabled via theTracer Summit, Tracer 100, orTracker system. The operatingrange of the setpoint knob can belimited to maintain system stabilitywhile still allowing for occupantcomfort control.

After Hours Override

Use either a space-mountedoverride button, or the Tracker,Tracer Summit, or Tracer 100system to temporarily provideoverride from the unoccupied tothe occupied mode. The systemcan also specify the length of theoverride period. An override for aspecific zone becomes an overridefor its group. The associated HVACunit operates in the occupied modefor the duration of the overrideperiod.

Group Control

The Tracker, Tracer Summit, orTracer 100 system enables accessto overrides by group. This allowsthe operator to manually controlthe groups’ occupied/unoccupiedmode, damper position override,and VAV terminal unit heater andfan mode if available. It also

provides for operation of aventilation cycle when the HVACunit is in a zero energy state. Thisprovides greater zone ventilationcapability without affectingcomfort.

System Status

The current operating status of theVariTrac system can be accessedthrough the Tracker or TracerSummit, or Tracer 100 system. Theoperator can view a servicesummary of the entire VariTracsystem at a glance, a more detailedview of each zone, or the currentoperating status of the HVAC unit.

Alarming and Alarm Log

The Tracker, Tracer Summit, orTracer 100 system has thecapability of monitoring VariTracfor system and zone alarms. Suchthings as sensor failure orcommunication loss can bemonitored. Custom alarms are alsoavailable. The system retains a listof past alarms in an alarm log foroperator review. If a Trane Voyagerrooftop is attached to the VariTracsystem, Voyager alarms can bemonitored.

Trane’s Integrated Comfort system(ICS) architecture integratesoperator workstations, buildingmanagement panels, and HVACequipment with microprocessor-based control modules for totalbuilding operating efficiency andcomfort. The ICS architecture alsointerfaces with other buildingsystems, such as fire alarm andlighting control.

The foldout on the previous pageillustrates the three levels of an ICSarchitecture:

• Operator interface

• Building control

• Unit control

Operator InterfacePC-based operator workstationsprovide an advanced graphicalinterface that enables operators toperform building operationfunctions quickly with minimalexperience and training. Thesetasks include:

• Viewing the status of thebuilding

• Changing setpoints

• Viewing and modifying schedules

• Responding to alarms

• Viewing historical reportinformation

Building ControlBuilding control functionsincluding energy management,equipment coordination, and alarmprocessing are performed by TracerSummit, Tracer 100 series, orTracker building managementpanels. These panels may belocated in a single facility or inremote buildings with dial-upaccess for communication.

ICS ArchitectureWith thousands of buildingmanagement panels in operation,the full line of Trane buildingmanagement systems is proventechnology.

Unit ControlTrane microprocessor-based unitcontrol modules provide pressure,temperature, and flow control ofHVAC equipment, in addition tomaking comprehensive diagnosticinformation available to buildingmanagement system operators.These Unit Control Modules(UCMs) are factory-mounted on abroad range of Trane equipment.

Auxiliary equipment withoutfactory-mounted UCMs, such ascooling towers, pumps, boilers, andnon-Trane HVAC equipment, can belinked through Trane field-installedcontrollers. These standalonedevices are the ideal base for theHVAC control system upgrades thatare often part of major facilityrenovations.

Remote OperationsThe Tracker system has advancedcommunication and operationcapability via a directly connectededit device, or remotely via anoptional internal modem. TheTracker features a standard RS-232port for connecting the editterminal. All status and setupfeatures previously discussed areaccessible through the RS-232 portor modem, along with theseadditional capabilities:

• Trend logs (up to 8) are availableto monitor any analog input inthe system.

• Custom alarms (up to 24) can beconfigured in addition to thestandard alarm list. These alarmscan be configured for automaticdial out via modem for remotealarm notification.

• Demand limiting . The Stat 16model is capable of demandmonitoring and limiting up to 24loads. All HVAC loads utilizetemperature-compensateddemand control to insureoccupant comfort. Twenty-fourhour and 35-day energy historyusage logs are available toprovide the operator withhistorical data on kW peaks andkWh consumption.

For more information about Tracker, refer toTrane publications BAS-TS-47 and BAS-S-18.

Simple Zoning ControlThe VariTrac II comfort controlsystem provides individualtemperature control to eachcomfort zone in a building whileusing the same single zone airconditioning unit. The VariTrac IIalso varies the flow of supply air toeach zone, providing the heating

and cooling capacity required tomatch the load in each specificzone.

ICS CapabilityThe VariTrac II Central ControlPanel (CCP) interfaces with theTracker, Tracer Summit, or Tracer100 series building managementsystem. It provides control,monitoring, and diagnostics of theindividual VariTrac dampers, CCP,and corresponding HVAC unit.

Software CapabilitiesThe VariTrac II CCP scans the zoneUCMs to determine the deviationsfrom setpoint, length of deviation,time from last heat or coolchangeover, and number of zonesrequiring heating or cooling. Basedon this information, the CCP selectsthe system heat or cool mode andstages of capacity. The CCP alsomonitors the system airtemperature to ensure that highand low temperature limits aremaintained.

The CCP monitors system airvelocity or static pressure and

VariTrac damper position to controlduct air pressure, and to maintainproper air velocity through theHVAC unit.

Group Control of ZonesAll VariTrac UCM zone dampers ona system can be designated as amember of one or four groups. Allgroup members respond togetherto group commands such as timedoverride, time of day control, airflow control overrides, andventilation settings.

Tracker, Tracer Summit, and Tracer100 Series Operating CapabilitiesOccupied/Unoccupied Mode

The Tracker, Tracer Summit, orTracer 100 series panel providestime of day control for the VariTracII zone groups. Each group on aVariTrac system can be individuallyscheduled, enabling greaterscheduling flexibility of each HVACsystem. When any group is in theoccupied mode, the associatedHVAC unit operates in theoccupied mode.


Operator InterfaceTracer Summit and BuildingManagement Network are theoptions available for high-leveloperator interface.

Operator interfaces provide globalcontrol and serve as acommunication link between theoperator and the buildingmanagement panels. Theseoperator interfaces use adistributed processing architecture,which shares information withbuilding control panels and unitcontrollers — the other two levelsof a building automation system.

Tracer Summit PC WorkstationThe PC Workstation is the primaryoperator interface for the TracerSummit system. Each PCWorkstation provides a graphicalinterface to system information.The operator can create and editsystem databases, view current andtrended information, acknowledgealarms, and perform operatoroverrides and other operatortransactions from the PCWorkstation. Extensive usabilitytesting incorporated into thedesign of the product makes theTracer Summit PC Workstationsoftware easy to use.

ICS CapabilityThe PC Workstation and the TracerSummit software serve as acommunication link between theoperator and the Building ControlUnits (BCUs) and other equipment.PC Workstations can be connectedand disconnected on an ARCNET orEthernet local area network (LAN)as needed. System operation is notdependent on the PC Workstation.

The Tracer Summit system uses anobject-oriented database thatresides in the BCUs. Each PC

Workstation contains a backupcopy of the fully distributeddatabase. The system is scanned atregular intervals to update thedatabase with changes made fromany PC Workstation.

Operators have the ability to viewthe current setup and configurationfor all unit controllers, inputs, andoutputs for a selected site. Thisinformation can be accessed by aPC Workstation onsite or remotelyvia a modem connection.Operators with the proper securityaccess can edit, add, or deleteobjects. Each editor uses a graphicinterface that allows quick and easyrevision of setup and configurationvalues.

Software CapabilitiesGraphical Operation

Graphics are the main method ofviewing the system. Graphicsshow building status information ata glance and allow you to movethrough the system just likewalking through the building. You

can also use the graphics to changesetpoints and override equipmentoperation. Using graphics in TracerSummit is as simple as surfing theWeb because Trane hasincorporated Microsoft’s InternetExplorer into Tracer Summit todisplay graphics.

Tracer Summit software includes alibrary of standard graphics for allTrane equipment and applicationsthat ship as part of the product.Custom graphics can be createdusing the graphics editor that isalso part of the software.

BACnet Standard Protocol

Compatibility

Tracer Summit systemcommunication is based onASHRAE/ANSI BACnet Standard135-1995 which standardizescommunications between the PCWorkstation, BCU, and otherBACnet-compatible devices. Thisenables interoperation with non-Trane building managementsystems and subsystems.

Tracker and VariTracZoning SystemSimple Building ControlThe Trane Tracker Stat system forlight commercial buildings isdesigned to make effective buildingcontrol simple and affordable. TheTracker provides microelectroniccontrol and monitoring of HVACsystems in new or existingbuildings. Tracker communicateson a serial communication linkwith packaged HVAC equipment,zone controllers, and auxiliarypoints of control, creating a totalIntegrated Comfort system. Trackerprovides the operator withmanagement information andcontrol either onsite or from aremote location.

The three models of the TrackerStat are the Stat 4, Stat 7, and Stat16. Each successive model hasadditional unit capacity and featurecapabilities for different buildingand system needs.

ICS CapabilityTracker can communicate over adata link with the following ICSunits:

• VariTrac II changeover-bypasszoning system with CentralControl Panel (CCP) and VariTraczone dampers

• Voyager packaged HVAC rooftopunits with micro controls

• Thermostat Control Modules

(TCMs) for controlling genericrooftop units, split systems, orheat pumps, and Slave TCMs forcontrolling miscellaneous loadssuch as fans and lights

Front Panel OperationUsing a simple 16-button keypadand 2-line LCD, the onsite operator

can perform the followingfunctions:

• Setpoint control allowsoperators to control heating andcooling setpoints for eachconnected ICS device for boththe occupied and unoccupiedmode.

• Time of day scheduling allowseach unit or load to beindividually scheduled for twoOn/Off periods per day for eachweekday, plus separate holidayand exception day scheduling.

• Holiday dates (up to 24) can bedefined for the Trackerscheduling program.

• Timed override allows theoperator to place any area or unitin the temporary occupied modefor up to four hours.

• Alarms and alarm log . Allconnected ICS devices arecapable of delivering alarms tothe Tracker panel. For example,Voyager Rooftops can alarm suchthings as compressor lockout or

airflow failure. The last 32 alarmevents are maintained in an alarmlog for viewing at the front panel.

Additional Software CapabilitiesIn addition to the operatorinterface capabilities, the Trackeralso provides the followingfeatures:

• Powerfail protection of theclock and database informationfor 14 days without usingbatteries


• Optimal start for each unit

• Unit fan mode control (On/Auto) for Voyager Rooftops andTCMs

• Language display in English,French, or Spanish

• Temperature display inFahrenheit or Celsius

• Password protection of thefront panel control is enabled atthe factory


Application Programs

Tracer Summit offers the followingcapabilities:

• Time of day scheduling controlsschedules for equipment for eachweekday, as well as for holidaysand exception days. Using timeof day schedules, the operatorcan define equipment start andstop times, optimal start andoptimal stop times, and nighteconomize times. Each dailyschedule can contain multipleactions. Time of day schedulesare easily copied from one day toanother, or from one area toanother.

• Area control allows the operatorto coordinate HVAC equipmentand lighting in specific areas of abuilding with the time of dayscheduling application. Unitcontrollers and binary outputscan be assigned as members ofan area; the area is thencontrolled instead of eachmember individually — makingsetpoint changes, scheduling, andoperator overrides easy andefficient.


coordinates air handling unitsand VAV Terminal Units within abuilding. VAV Terminal Units areassigned to the air handling unitthat supplies air to the terminalunit, then VAV air system controlcoordinates system startup andshutdown to assure proper staticpressure control.

• Custom programming language

(CPL) allows the BCU to becustomized for the application(s)it provides. CPL routines can becreated to accommodate anynon-standard control strategiesand are used to sequence

equipment, calculate setpointsand values, and performshutdown sequences. CPLroutines can be edited,downloaded, uploaded, andtested while the PC Workstationis online or offline with theBCUs.

• Reports and trends allows theoperator to view system data intwo primary reports: a live or logreport, or a historical trend orreport. Live reports provide arecord of system conditions atone point in time and are used tolook at ICS equipment status,system logs, and to view monthlyconditions.

Historical reports are used tolook at numerous data samplesover a fixed time interval. Trends,monthly energy reports,refrigerant management reports,and indoor air quality reports areexamples of historical reports.

All reports can be viewed onscreen, printed as shown onscreen, or exported to a

spreadsheet program to createcharts and graphs.

• Diagnostics ensure that devicessuch as modems, printers, andcommunication links areoperating properly.

• Programming interfaces withPCM and UPCM Edit software.This software allows the operatorto edit the DDC loops andprogram logic in theseprogrammable controllers.

• Remote communications allowsa PC Workstation to access aTracer Summit site remotelyusing standard telephonemodems. This enables anoperator to change setpointsfrom home, or for servicetechnicians to changeconfiguration from their office asif they were at the site.

The remote communicationfunction also provides the abilityto dial out alarms. The TracerSummit system can beconfigured to dial out alarms to

• Demand limiting monitors thebuilding’s electrical demand andturns off certain electrical loadsor resets equipment setpointswhen demand exceeds aspecified limit. This helps toreduce peak power demand andsubsequent utility costs. Eachdemand limited load has amaximum off time andtemperature limits to ensureoccupant comfort.

• Chiller sequencing sequencesand automatically rotates up tosix chillers and their associatedpumps to control and monitorchiller operation. Thesequencing program can be usedto control virtually any type ofwater chiller.

• Priority control allows theoperator to define customcontrol sequences that respondto alarm conditions. Prioritycontrol sequences receive thehighest priority, overriding allother control sequences.

• Process control language (PCL)

allows the operator to createcustom control sequences, whichcomplement standard controlprograms by addressing abuilding’s individualrequirements. PCL routinesperform calculations based onreal time data, and can use analogand binary point values, alarmstatus, constants, equationvariables, and mathematical andlogical operations.

• Timed override allows theoperator to temporarily turn on adevice or a specified equipmentgroup that was scheduled off.Timed override can be activatedby a switch on a zone sensor orby a keyboard command from aCRT. Weekly and monthly timed

override reports document after-hours operation.

(CPL) allows the BCU to becustomized for the application(s)it provides. CPL routines can becreated to accommodate anynon-standard control strategiesand are used to sequence

equipment, calculate setpointsand values, and performshutdown sequences. CPLroutines can be edited,downloaded, uploaded, andtested while the PC Workstationis online or offline with theBCUs.

• Reports and trends allows theoperator to view system data intwo primary reports: a live or logreport, or a historical trend orreport. Live reports provide arecord of system conditions atone point in time and are used tolook at ICS equipment status,system logs, and to view monthlyconditions.

Historical reports are used tolook at numerous data samplesover a fixed time interval. Trends,monthly energy reports,refrigerant management reports,and indoor air quality reports areexamples of historical reports.

All reports can be viewed onscreen, printed as shown onscreen, or exported to a

spreadsheet program to createcharts and graphs.

• Diagnostics ensure that devicessuch as modems, printers, andcommunication links areoperating properly.

• Programming interfaces withPCM and UPCM Edit software.This software allows the operatorto edit the DDC loops andprogram logic in theseprogrammable controllers.

• Remote communications allowsa PC Workstation to access aTracer Summit site remotelyusing standard telephonemodems. This enables anoperator to change setpointsfrom home, or for servicetechnicians to changeconfiguration from their office asif they were at the site.

The remote communicationfunction also provides the abilityto dial out alarms. The TracerSummit system can beconfigured to dial out alarms to

• Demand limiting monitors thebuilding’s electrical demand andturns off certain electrical loadsor resets equipment setpointswhen demand exceeds aspecified limit. This helps toreduce peak power demand andsubsequent utility costs. Eachdemand limited load has amaximum off time andtemperature limits to ensureoccupant comfort.

• Chiller sequencing sequencesand automatically rotates up tosix chillers and their associatedpumps to control and monitorchiller operation. Thesequencing program can be usedto control virtually any type ofwater chiller.

• Priority control allows theoperator to define customcontrol sequences that respondto alarm conditions. Prioritycontrol sequences receive thehighest priority, overriding allother control sequences.

• Process control language (PCL)

allows the operator to createcustom control sequences, whichcomplement standard controlprograms by addressing abuilding’s individualrequirements. PCL routinesperform calculations based onreal time data, and can use analogand binary point values, alarmstatus, constants, equationvariables, and mathematical andlogical operations.

• Timed override allows theoperator to temporarily turn on adevice or a specified equipmentgroup that was scheduled off.Timed override can be activatedby a switch on a zone sensor orby a keyboard command from aCRT. Weekly and monthly timed

override reports document after-hours operation.

Refer to the Operator Interfacesection of this catalog for moreinformation about BuildingManagement Network.

For more information refer to Trane publicationBAS-S-10.


Operator InterfaceTracer Summit and BuildingManagement Network are theoptions available for high-leveloperator interface.

Operator interfaces provide globalcontrol and serve as acommunication link between theoperator and the buildingmanagement panels. Theseoperator interfaces use adistributed processing architecture,which shares information withbuilding control panels and unitcontrollers — the other two levelsof a building automation system.

Tracer Summit PC WorkstationThe PC Workstation is the primaryoperator interface for the TracerSummit system. Each PCWorkstation provides a graphicalinterface to system information.The operator can create and editsystem databases, view current andtrended information, acknowledgealarms, and perform operatoroverrides and other operatortransactions from the PCWorkstation. Extensive usabilitytesting incorporated into thedesign of the product makes theTracer Summit PC Workstationsoftware easy to use.

ICS CapabilityThe PC Workstation and the TracerSummit software serve as acommunication link between theoperator and the Building ControlUnits (BCUs) and other equipment.PC Workstations can be connectedand disconnected on an ARCNET orEthernet local area network (LAN)as needed. System operation is notdependent on the PC Workstation.

The Tracer Summit system uses anobject-oriented database thatresides in the BCUs. Each PC

Workstation contains a backupcopy of the fully distributeddatabase. The system is scanned atregular intervals to update thedatabase with changes made fromany PC Workstation.

Operators have the ability to viewthe current setup and configurationfor all unit controllers, inputs, andoutputs for a selected site. Thisinformation can be accessed by aPC Workstation onsite or remotelyvia a modem connection.Operators with the proper securityaccess can edit, add, or deleteobjects. Each editor uses a graphicinterface that allows quick and easyrevision of setup and configurationvalues.

Software CapabilitiesGraphical Operation

Graphics are the main method ofviewing the system. Graphicsshow building status information ata glance and allow you to movethrough the system just likewalking through the building. You

can also use the graphics to changesetpoints and override equipmentoperation. Using graphics in TracerSummit is as simple as surfing theWeb because Trane hasincorporated Microsoft’s InternetExplorer into Tracer Summit todisplay graphics.

Tracer Summit software includes alibrary of standard graphics for allTrane equipment and applicationsthat ship as part of the product.Custom graphics can be createdusing the graphics editor that isalso part of the software.

BACnet Standard Protocol

Compatibility

Tracer Summit systemcommunication is based onASHRAE/ANSI BACnet Standard135-1995 which standardizescommunications between the PCWorkstation, BCU, and otherBACnet-compatible devices. Thisenables interoperation with non-Trane building managementsystems and subsystems.

Tracker and VariTracZoning SystemSimple Building ControlThe Trane Tracker Stat system forlight commercial buildings isdesigned to make effective buildingcontrol simple and affordable. TheTracker provides microelectroniccontrol and monitoring of HVACsystems in new or existingbuildings. Tracker communicateson a serial communication linkwith packaged HVAC equipment,zone controllers, and auxiliarypoints of control, creating a totalIntegrated Comfort system. Trackerprovides the operator withmanagement information andcontrol either onsite or from aremote location.

The three models of the TrackerStat are the Stat 4, Stat 7, and Stat16. Each successive model hasadditional unit capacity and featurecapabilities for different buildingand system needs.

Trane is uniquely qualified toimplement system-wide strategiesfor energy efficiency, refrigerantmanagement, and indoor air qualitybased on expertise gained fromthousands of building automationinstallations and more than 80years as an HVAC systems provider.

Trane’s Integrated Comfort system(ICS) architecture integratesoperator workstations, buildingmanagement panels, and HVACequipment with microprocessor-based control modules for totalbuilding operating efficiency andcomfort. The ICS architecture alsointerfaces with other buildingsystems, such as fire alarm andlighting control.

The foldout on the previous pageillustrates the three levels of an ICSarchitecture:

• Operator interface

• Building control

• Unit control

Operator InterfacePC-based operator workstationsprovide an advanced graphicalinterface that enables operators toperform building operationfunctions quickly with minimalexperience and training. Thesetasks include:

• Viewing the status of thebuilding

• Changing setpoints

• Viewing and modifying schedules

• Viewing historical reportinformation

Building ControlBuilding control functionsincluding energy management,equipment coordination, and alarmprocessing are performed by TracerSummit, Tracer 100 series, orTracker building managementpanels. These panels may belocated in a single facility or inremote buildings with dial-upaccess for communication.

ICS ArchitectureWith thousands of buildingmanagement panels in operation,the full line of Trane buildingmanagement systems is proventechnology.

Unit ControlTrane microprocessor-based unitcontrol modules provide pressure,temperature, and flow control ofHVAC equipment, in addition tomaking comprehensive diagnosticinformation available to buildingmanagement system operators.These Unit Control Modules(UCMs) are factory-mounted on abroad range of Trane equipment.

Auxiliary equipment withoutfactory-mounted UCMs, such ascooling towers, pumps, boilers, andnon-Trane HVAC equipment, can belinked through Trane field-installedcontrollers. These standalonedevices are the ideal base for theHVAC control system upgrades thatare often part of major facilityrenovations.

Remote OperationsThe Tracker system has advancedcommunication and operationcapability via a directly connectededit device, or remotely via anoptional internal modem. TheTracker features a standard RS-232port for connecting the editterminal. All status and setupfeatures previously discussed areaccessible through the RS-232 portor modem, along with theseadditional capabilities:

• Trend logs (up to 8) are availableto monitor any analog input inthe system.

• Custom alarms (up to 24) can beconfigured in addition to thestandard alarm list. These alarmscan be configured for automaticdial out via modem for remotealarm notification.

• Demand limiting . The Stat 16model is capable of demandmonitoring and limiting up to 24loads. All HVAC loads utilizetemperature-compensateddemand control to insureoccupant comfort. Twenty-fourhour and 35-day energy historyusage logs are available toprovide the operator withhistorical data on kW peaks andkWh consumption.

For more information about Tracker, refer toTrane publications BAS-TS-47 and BAS-S-18.

Simple Zoning ControlThe VariTrac II comfort controlsystem provides individualtemperature control to eachcomfort zone in a building whileusing the same single zone airconditioning unit. The VariTrac IIalso varies the flow of supply air toeach zone, providing the heating

and cooling capacity required tomatch the load in each specificzone.

ICS CapabilityThe VariTrac II Central ControlPanel (CCP) interfaces with theTracker, Tracer Summit, or Tracer100 series building managementsystem. It provides control,monitoring, and diagnostics of theindividual VariTrac dampers, CCP,and corresponding HVAC unit.

Software CapabilitiesThe VariTrac II CCP scans the zoneUCMs to determine the deviationsfrom setpoint, length of deviation,time from last heat or coolchangeover, and number of zonesrequiring heating or cooling. Basedon this information, the CCP selectsthe system heat or cool mode andstages of capacity. The CCP alsomonitors the system airtemperature to ensure that highand low temperature limits aremaintained.

The CCP monitors system airvelocity or static pressure and

VariTrac damper position to controlduct air pressure, and to maintainproper air velocity through theHVAC unit.

Group Control of ZonesAll VariTrac UCM zone dampers ona system can be designated as amember of one or four groups. Allgroup members respond togetherto group commands such as timedoverride, time of day control, airflow control overrides, andventilation settings.

Tracker, Tracer Summit, and Tracer100 Series Operating CapabilitiesOccupied/Unoccupied Mode

The Tracker, Tracer Summit, orTracer 100 series panel providestime of day control for the VariTracII zone groups. Each group on aVariTrac system can be individuallyscheduled, enabling greaterscheduling flexibility of each HVACsystem. When any group is in theoccupied mode, the associatedHVAC unit operates in theoccupied mode.


The system can provide multipleOn/Off time periods per day foreach of the seven weekdays. It alsocan provide:

• Holiday schedules and multipleholiday dates

• Exception day schedules


• Optimal start by group

Setpoint Control

The system allows the operator tocontrol setpoints for all VariTraczone UCMs. Setpoint controlincludes occupied and unoccupiedheating and cooling setpoints, andair volume minimum andmaximum setpoints. If desired, usea setpoint control mounted on thezone sensor. The setpoint knob canbe enabled and disabled via theTracer Summit, Tracer 100, orTracker system. The operatingrange of the setpoint knob can belimited to maintain system stabilitywhile still allowing for occupantcomfort control.

After Hours Override

Use either a space-mountedoverride button, or the Tracker,Tracer Summit, or Tracer 100system to temporarily provideoverride from the unoccupied tothe occupied mode. The systemcan also specify the length of theoverride period. An override for aspecific zone becomes an overridefor its group. The associated HVACunit operates in the occupied modefor the duration of the overrideperiod.

Group Control

The Tracker, Tracer Summit, orTracer 100 system enables accessto overrides by group. This allowsthe operator to manually controlthe groups’ occupied/unoccupiedmode, damper position override,and VAV terminal unit heater andfan mode if available. It also

provides for operation of aventilation cycle when the HVACunit is in a zero energy state. Thisprovides greater zone ventilationcapability without affectingcomfort.

System Status

The current operating status of theVariTrac system can be accessedthrough the Tracker or TracerSummit, or Tracer 100 system. Theoperator can view a servicesummary of the entire VariTracsystem at a glance, a more detailedview of each zone, or the currentoperating status of the HVAC unit.

Alarming and Alarm Log

The Tracker, Tracer Summit, orTracer 100 system has thecapability of monitoring VariTracfor system and zone alarms. Suchthings as sensor failure orcommunication loss can bemonitored. Custom alarms are alsoavailable. The system retains a listof past alarms in an alarm log foroperator review. If a Trane Voyagerrooftop is attached to the VariTracsystem, Voyager alarms can bemonitored.

General-Purpose Unit ControlGeneral-purpose controllersprovide the capability to tie Traneequipment without unit controlmodules and non-Trane equipmentinto the Trane communicationnetwork. Products include theThermostat Control Module,Programmable Control Module, andthe Universal ProgrammableControl Module.

Thermostat Control ModuleThe Thermostat Control Module(TCM) provides a basic yetpowerful interface between TracerSummit, Tracer 100 series, orTracker systems and mechanicalequipment.

The TCM can extend the IntegratedComfort system (ICS) technologyto existing, auxiliary, and non-Traneequipment. The TCMcommunicates with a buildingcontroller over a singlecommunication link.

ICS CapabilityThe TCM provides an interfacebetween the building control paneland equipment not having TraneUnit Control Modules (UCMs), suchas lighting, fans, and non-Traneunitary equipment normallyoperated by a standard thermostat.

Software CapabilitiesThe TCM can function either as a 2-stage heat/2-stage cool thermostatfor air conditioning units and heatpumps, or as a provider of slavepoints for the buildingmanagement panel.

In thermostat mode, the TCMmonitors its sensors and controlsits outputs like a wall thermostat.The TCM can be configured aseither a 2-stage heat/2-stage cool airconditioning thermostat or a heatpump thermostat. This controlresides in the TCM, and the TCMcan operate standalone (withoutthe building management panel)during system startup or whenthere is a communication loss.

In slave mode, the buildingcontroller monitors the TCM inputsand directly controls the TCMoutputs. The TCM input andoutput points function as thoughthey are hardwired, generic pointson the building control panel.

The building control panelprovides control such as time ofday scheduling and demandlimiting.

See the appropriate BuildingControl section of this catalog fordetails on each panel’s capabilities.

Trane SensorsControlling the comfort in abuilding space begins with Tranesensors. We designed our sensorsfor use with Trane Tracer systemsto provide the accuracy andrepeatability required by DDCcontrol. Trane sensors arecompatible with a variety of Tranebuilding level and unit levelcontrollers. In addition, thesensors are architecturallycompatible with each other andwith modern building interiors.

Sensor CapabilitiesTrane room temperature sensorsare available in several variations,and include options for setpointadjustment and override switches.Use Trane room humidity sensorsto control humidifiers anddehumidification equipment.Controlling building humidity is animportant element in maintainingindoor air quality. Trane also offersfield-applied sensors to measurepressure, temperature, andhumidity in air and waterapplications.

CO2 Sensor CapabilitiesCarbon dioxide is present in the airin variable amounts and can bemeasured in parts per million(PPM) by the Trane CarbonDioxide (CO2) Sensor. Elevatedconcentrations of carbon dioxidein a building zone can indicate aspace is occupied above designconditions, or that there is a

problem or deficiency with thebuilding’s ventilation system.

When connected to a Tracerbuilding management system andthe appropriate ventilationequipment, the Trane CO2 Sensorprovides building designers,operators, and owners a practicaland affordable means to respond toconcerns of indoor air quality andoccupant comfort.

Typical applications for the CO2Sensor include:

• Monitoring and recording CO2

levels in occupied buildingspaces

• Identifying underventilated

building zones

• Overriding outdoor air flow

beyond design ventilation rates ifCO2 exceeds an acceptable level

• Using CO2 measurement toidentify changes in occupancy

of a space

Hardware Description

The Trane CO2 Sensor can eitherbe wall-mounted or duct-mountedusing an optional duct enclosurekit.
