Features and Benefits

RT-PRC014-E44

• The Micro requires no special tools torun the unit through its paces. Simplyplace a jumper between Test 1 and Test2 terminals on the Low Voltage TerminalBoard and the unit will walk through itsoperational steps automatically. Theunit automatically returns control to thezone sensor after stepping through thetest mode a single time, even if thejumper is left on the unit.

• As long as the unit has power and theLED is lit, the Micro is operational. Thelight indicates that the Micro isfunctioning properly.

• The Micro features expandeddiagnostic capabilities when utilizedwith Trane's Integrated Comfort™Systems.

• The Micro in the Voyager units has built-in anti-short-cycle timers, time delayrelays and minimum ''on'' time controls.These controls are functions of the Microand are factory tested to assure properoperation.

• The Micro softens electrical ''spikes'' bystaging on fans, compressors andheaters.

• The Intelligent Fallback or AdaptiveControl is a benefit to the buildingoccupant. If a component goes astray,the unit will continue to operate atpredetermined temperature set points.

• Intelligent Anticipation is a standardfeature of the Micro. It functionsconstantly as the Micro and zonesensor work together in harmony toprovide tighter comfort control thanconventional electro-mechanicalthermostats.

Drum And Tube Heat Exchanger

• The drum and tube heat exchanger isdesigned for increased efficiency andreliability and has utilized improvedtechnology incorporated in the largerooftop commercial units for almost20 years.

• The heat exchanger is manufacturedusing aluminized steel with stainlesssteel components for maximumdurability. The drum and tube design hasbeen tested and passed over150,000 cycles.

• The negative pressure gas valve will notallow gas flow unless the combustionblower is operating. This is one of ourunique safety features.

• The forced combustion blower suppliesa gas-air mixture through a singlestainless steel burner screen into asealed drum where ignition takes place.It is more reliable to operate andmaintain than a multiple burnersystem.

• The hot surface ignitor is a gas ignitiondevice which doubles as a safety deviceutilizing a continuous test to prove theflame.

Weather Tight Top and C abinet

• Voyager units incorporate the Trane-Tite-Top (T3 ). Each part of the top(three pieces) overlaps in such a waythat water cannot leak into the unit.These overlapped edges are gasketedand sealed to ensure superior waterintegrity.

• Quick- Access panels reduce thenumber of possible water entry points.

• For added water integrity, Voyager hasa raised 30 mm lip around the supplyand return of the downflow units toprevent water from blowing into theductwork.

Quality And Reliability

• The fan and idler arm assemblydesigns have been tested to over300,000 cycles each.

• All of Voyager's designs wererigorously rain tested at the factory toensure water integrity.

• We perform a 100% coil leak test at thefactory. The evaporator and condensercoils are leak tested at 1.4 MPa andpressure tested to 3.1 MPa.

• Every unit and its options receive a100% unit run test before leaving theproduction line to make sure it lives upto Trane r equirements.

Figure 1 - High performance Scrollcompressor

Compressors

Ease Of Installation

Voyager units provide many time andmoney saving features.

Conversionless Units

• The dedicated design units (eitherdownflow or horizontal) require nopanel removal or alteration time toconvert in the field.

• Horizontal units come complete withduct flanges so the contractor doesn'thave to field fabricate them.

Improved Airflow

• U-shaped airflow allows for improvedstatic capabilities.

Single Side Access

• No more than three screws must beremoved to access components.

Trane's Idler Arm Assembly

• On most units, our idler pulley providesquick- adjustment for belt or motorsheaves. No longer does one have toadjust the motor to tighten the belt orchange the motor sheave setting.

Variable Speed Direct DriveSupply Fan

Efficient, flexible and low maintenancedirect driven fan

High efficiency fan

Direct transmission, variable speed drivesdelivers energy saving through 3 aspects:

• Higher fan nominal efficiency: The pulleyno longer penalizes the airflow streamat the an inlet, resulting in less turbulenceand higher fan static efficiency.

• Direct coupling drive efficiency: Thedirect coupling concept avoids losses bybelt friction. Classic belt drive is depletespart of the motor power caused byimproper belt tension, pulley mis-alignment. The direct driven fan improvesmotor consumption by about 15% to20% compared to belt driven fan.

• Reduction of power input with fan speedmodulation at part load or in ventilationmode. Substantial energy savings canbe achieved by reducing fan speed byonly 20%, resulting in 20% less airflowand 50% less absorbed power. On atypical application, the result is an annualenergy saving of 30% of the total rooftopconsumption.

• Power factor of the fan motor iscorrected and inrush current is very lowthanks to progressive fan ramp up start(by default: 1 minute ramp up time).

Reduced maintenance costs with:

• Almost no maintenance direct couplingcompared to belt drive.

• Easy commissioning with adjustment ofnominal airlfow and ramp up time forprogressive textile duct inflation.

Serviceability

Voyager's Simpler Design

The Voyager design uses up to 42%fewer parts than previous units. Sinceit is simpler in design, it is easier todiagnose.

Reliatel

• Reliatel requires no special tools to runthe Voyager unit through its paces.Simply press the Test button locatedon the right side of the control paneland the unit will walk through itsoperational steps automatically.

• As long as the unit has power andthe LED is lit, Reliatel is operational.The light indicates that the Micro isfunctioning properly.

• Reliatel features expanded diagnosticcapabilities when utilized with Trane'sIntegrated Comfort TM Systems.

• One Zone Sensor option has centralcontrol panel lights which indicatethe mode the unit is in and possiblediagnostic information (dirty filtersfor example).

Standardized Components

• Components are placed in the samelocation for all Voyager units.

Easy Access Low Voltage Terminal

Board

• The thermostat wires must beconnected to the terminals located onthe main board.

An Answer to MarketNeeds

Capacity Modulation

• Voyager features dual Scrollcompressor units. The dual compressormodels are outstanding for humiditycontrol, light load cooling conditionsand system back-up applications.

Low Ambient Cooling

• All Voyager units have coolingcapabilities down to -18°C as standard.

Flexible Applications

• Thanks to its high static pressurecapabilities, the Voyager can replace anolder machine with old ductwork and,in some cases, improve the comfortthrough better air distribution.

Indoor Air Quality

• Filters - all rooftops are shipped withthrowaway filters to be used during thefirst days of operation (usually the jobsite is not completely clean, and highefficiency filters would get dirty in a fewhours - this would be a waste ofmoney) or G4/EU4 filters for regularoperation.

• Panels in the indoor air section have afire-resistant (MO) aluminum foil-facedinsulation. There is no more insulationpaticules carried in the air. It can becleaned which is paricuarly interestingfor restaurant applications.

• All our drain pans are sloped. We thusavoid water stagnation that engenderscorrosion and micro-organism life suchas mold and fungi.

Reliatel Benefits

• Reliatel in the Voyager units has built-inanti-short-cycle timers, time delayrelays and minimum ''on'' timecontrols. These controls are functions ofReliatel and are factory tested to assureproper operation.

• Reliatel softens electrical ''spikes'' bystaging on fans, compressors andheaters.

• The Intelligent Fallback or AdaptiveControl is a benefit to the buildingoccupant. If a component goes astray,the unit will continue to operate atpredetermined temperature set points.

• Intelligent Anticipation is a standardfeature of Reliatel. It functionsconstantly as Reliatel and zone sensorwork together in harmony to providetighter comfort control thanconventional electro-mechanicalthermostats.

Downflow And Horizontal Economizers

• Economizers come with a comparativeenthalpy control.

Equipment Protection/OperationTimings and Features

Increased reliability

Fewer components (movingelectromechanical parts); lesslikelihood of equipment down timeor failure. Standard

Proportional Integral (PI) Control

Proportional - sets corrective actionproportional to deviation fromsetpoint. Integral - fine-tunes therate of corrective action proportionalto the error (results in superiortemperature control). Standard

Built In "TEST" Mode

Aids in quick verification of systemand control operation; exercisesboth hardware and software (nospecial tools required). Standard

On Board Diagnostics

Assists with equipmenttroubleshooting if a problem shouldoccur. Standard

Low Ambient Start Timer (LAST)Function

Bypasses low pressure control whena compressor starts, eliminatingnuisance compressor lockouts.Standard

Anti Short Cycle Timer (ASCT)Function

Provides a three minute minimum"ON" time and a three minuteminimum "OFF" time forcompressors; enhances compressorreliability by ensuring proper oilreturn. Standard

Time Delay Relay (TDR) Function

Provides an incremental stagingdelay between compressors;minimizes equipment current inrushand consumption by keepingcompressors from startingsimultaneously. Standard

Built In Fan Delay Relay (FDR)

Provides custom indoor fan timingsequences for the different types ofequipment, enhancing efficiencyand reliability. Standard

Built in Evaporator Defrost Control

Provides low ambient cooling downto -18°C. Standard

Intelligent Fallback

Built-in Default Control providesadaptive operation, which allowsthe equipment to continue tooperate, and provide comfort in theevent of certain input failures. Also,allows temporary operation withouta thermostat. Standard

Emergency Stop Terminals on LowVoltage Terminal Board

Provides a convenient point todisable the equipment completelyand immediately. Standard

Lower Installation Cost

When using a Trane THS03 or THP03,control voltage wiring may be runup to five times further than anyelectromechanical system with noincrease in wire section. Example:Electromechanical System - 22 musing 0.5 mm2 wire. MicrocontrolSystem (THS/P 03) 110 m 0.5 mm2wire. Standard

Alternating Lead/Lag

During periods of part loadoperation, each compressor cyclesalternately as circuit number one,equalizing compressor wear and runtime. Enable by cutting the wire atRTRM junction number J3-8.

Demand defrost - Heat pump

Defrost only if needed; not based ontime like most other systems.Adapts to changing weatherconditions and lowers operatingcosts. Standard

RT-PRC014-E4_1112:BAT2 30.5.2013 11:01

Controls

21RT-PRC014-E4

Heat pump Soft Start

Provides a smooth transition intoheating after defrost, minimizingnoise and compressor stressassociated with switch over.Standard

Heat pump Smart Recovery andSmart Staging

Inhibits auxiliary heat operation ifthe space is recovering adequately(0.1°C /min) with the heat pumpalone, providing considerablesavings in operating costs. Standard

Economizer Preferred Cooling

Provides fully integrated operation.Will not turn on a compressor withthe economizer, if the space isrecovering adequately with theeconomizer alone (0.1°C./minute).Allows the equipment to be utilizedin more varied applications.Standard with economizer

Features lost when using aconventional thermostat

• When a Conventional Thermostatis applied, equipment operationdiffers significantly. The basicequipment protection featuresremain intact, and the followingfeatures end benefits are lost :

• Proportional Integral (PI) control islost, equipment is controlled by athermostat or generic buildingautomation system device.

• Intelligent Fall Back is lost, if afailure occures in the devicecontrolling the equipment,operation will cease.

• Heat Pump Smart Recovery andSmart Staging is not available.Heat Pump operation becomesmore costly unless the genericcontrol applied can accomplishthis.
