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 thebuildings 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 underventilatedbuilding zones

Overriding outdoor air flowbeyond 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.

For more information on the CO2 Sensor, referto Trane publication BAS-PD-8.

IntelliPak Rooftop UnitsThe 20- to 130-ton IntelliPakRooftop is a self-contained heatingand cooling air handling unit. TheIntelliPak can be configured aseither constant volume or variableair volume system control. TheIntelliPak UCM is factory-installedon each unit, and can be connectedto a Tracer Summit BCU or a Tracer100 series controller via a TraneCommunication Interface (TCI).Each system provides control,monitoring, and diagnostics for therooftop unit.

For more information about IntelliPak Rooftops,refer to Trane publication RT-DS-8.

Voyager Rooftop UnitsThe 3- to 50-ton Voyager Rooftopunit is a self-contained heating andcooling air conditioner normallyinstalled on a buildings roof. Wedesigned the Voyager Rooftop tocompete in the price-competitivemarket of light commercialpackaged rooftops. The Voyagercan be factory-configured for eitherconstant volume or variable airvolume (27- to 50-ton VoyagerCommercial only) system control.The Voyager Micro is applied on allTrane Voyager Rooftops and can beconnected to a Tracer Summit BCU,a Tracer 100 series controller or aTracker panel via a TCI. Eachsystem provides control,monitoring, and diagnostics for therooftop unit.

For more information about Voyager Rooftops,refer to Trane publications RT-DS-9, YC-D-7,WC-D-4, and TC-D-5.
