Compressors Voyager contains the best Scroll compressor technology available, in order to achieve the highest performance possible. The Trane Voyager™ rooftop has among the best COP in its class. All performances are Eurovent certi ed which provides the assurance of accurate performance and common comparison criteria ReliaTel™ Micro Controls The Micro provides unit control for heating, cooling and ventilating utilizing input from sensors that measure outdoor and indoor temperature. The Micro improves quality and reliability through the use of timetested microprocessor controls and logic. prevents the unit from short cycling, considerably improving compressor life. ensures that the compressor will run for a speci c amount of time which allows oil to return for better lubrication, enhancing the reliability of the compressor. reduces the number of components required to operate the unit, thereby reducing possibilities for component failure. The Micro requires no special tools to run the unit through its paces. Simply place a jumper between Test 1 and Test 2 terminals on the Low Voltage Terminal Board and the unit will walk through its operational steps automatically. The unit automatically returns control to the zone sensor after stepping through the test mode a single time, even if the jumper is left on the unit. As long as the unit has power and the LED is lit, the Micro is operational. The light indicates that the Micro is functioning properly. The Micro features expanded diagnostic capabilities when utilized with Trane’s Integrated Comfort™ Systems. The Micro in the Voyager units has builtin anti-short- cycle timers, time delay relays and minimum ‘’on’’ time controls. These controls are functions of the Micro and are factory tested to assure proper operation. The Micro softens electrical ‘’spikes’’ by staging on fans, compressors and heaters. The Intelligent Fallback or Adaptive Control is a bene t to the building occupant. If a component goes astray, the unit will continue to operate at predetermined temperature set points. Intelligent Anticipation is a standard feature of the Micro. It functions constantly as the Micro and zone sensor work together in harmony to provide tighter comfort control than conventional electro-mechanical thermostats. Drum And Tube Heat Exchanger The drum and tube heat exchanger is designed for increased ef ciency and reliability and has utilized improved technology incorporated in the large rooftop commercial units for almost 20 years. The heat exchanger is manufactured using aluminized steel with stainless steel components for maximum durability. The drum and tube design has been tested and passed over 150,000 cycles. The negative pressure gas valve will not allow gas ow unless the combustion blower is operating. This is one of our unique safety features. The forced combustion blower supplies a gas-air mixture through a single stainless steel burner screen into a sealed drum where ignition takes place. It is more reliable to operate and maintain than a multiple burner system. The hot surface ignitor is a gas ignition device which doubles as a safety device utilizing a continuous test to prove the ame. 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 way that water cannot leak into the unit. These overlapped edges are gasketed and sealed to ensure superior water integrity. Quick- Access panels reduce the number of possible water entry points. For added water integrity, Voyager has a raised 30 mm lip around the supply and return of the down ow units to prevent water from blowing into the ductwork. Figure 1 – High performance Scrollcompressor RT-PRC014H-E4 4 Features and Benefits
Quality And Reliability The fan and idler arm assembly designs have been tested to over 300,000 cycles each. All of Voyager’s designs were rigorously rain tested at the factory to ensure water integrity. We perform a 100% coil leak test at the factory. The evaporator and condenser coils are leak tested at 1.4 MPa and pressure tested to 3.1 MPa. Every unit and its options receive a 100% unit run test before leaving the production line to make sure it lives up to Trane r equirements. Ease Of Installation Voyager units provide many time and money saving features. Conversionless Units The dedicated design units (either down ow or horizontal) require no panel removal or alteration time to convert in the eld. Horizontal units come complete with duct anges so the contractor doesn’t have to eld fabricate them. Improved Airfl ow ow allows for improved static capabilities. Single Side Access No more than three screws must be removed to access components. Trane’s Idler Arm Assembly On most units, our idler pulley provides quick- adjustment for belt or motor sheaves. No longer does one have to adjust the motor to tighten the belt or change the motor sheave setting. Figure 2 – Idler arm assembly Variable Speed Direct Drive Supply Fan Ef cient, exible and low maintenance direct driven fan. High effi ciency fan Direct transmission, variable speed drives delivers energy saving through 3 aspects: Higher fan nominal ef ciency: The pulley no longer penalizes the air ow stream at the an inlet, resulting in less turbulence and higher fan static ef ciency. Direct coupling drive ef ciency: The direct coupling concept avoids losses by belt friction. Classic belt drive is depletes part of the motor power caused by improper belt tension, pulley misalignment. The direct driven fan improves motor consumption by about 15% to 20% compared to belt driven fan. Reduction of power input with fan speed modulation at part load or in ventilation mode. Substantial energy savings can be achieved by reducing fan speed by only 20%, resulting in 20% less air ow and 50% less absorbed power. On a typical application, the result is an annual energy saving of 30% of the total rooftop consumption. Power factor of the fan motor is corrected and inrush current is very low thanks to progressive fan ramp up start (by default: 1 minute ramp up time). Reduced maintenance costs with: Almost no maintenance direct coupling compared to belt drive. Easy commissioning with adjustment of nominal airlfow and ramp up time for progressive textile duct in ation. Serviceability Voyager’s Simpler Design The Voyager design uses up to 42% fewer parts than previous units. Since it is simpler in design, it is easier to diagnose. Reliatel Reliatel requires no special tools to run the Voyager unit through its paces. Simply press the Test button located on the right side of the control panel and the unit will walk through its operational steps automatically. As long as the unit has power and the LED is lit, Reliatel is operational. The light indicates that the Micro is functioning properly. Reliatel features expanded diagnostic capabilities when utilized with Trane’s Integrated Comfort™ Systems. RT-PRC014H-E4 5 Features and Benefi ts
One Zone Sensor option has central control panel lights which indicate the mode the unit is in and possible diagnostic information (dirty lters for example). Figure 3 – RTRM (ReliaTel™ Refrigeration Module) Standardized Components Components are placed in the same location for all Voyager units. Easy Access Lo w Voltage Terminal Board The thermostat wires must be connected to the terminals located on the main board. Single Point Power A single electrical connection powers the unit. Figure 4 – Variable speed direct drive supply fan An Answer to Market Needs Capacity Modulation Voyager features dual Scroll compressor units. The dual compressor models are outstanding for humidity control, light load cooling conditions and system back-up applications. Low Ambient Cooling All Voyager units have cooling capabilities down to -18°C as standard. Flexible Applications Thanks to its high static pressure capabilities, the Voyager can replace an older machine with old ductwork and, in some cases, improve the comfort through better air distribution.

RT-PRC014H-E4 7 Indoor Air Quality Filters - all rooftops are shipped with throwaway lters to be used during the rst days of operation (usually the job site is not completely clean, and high ef ciency lters would get dirty in a few hours - this would be a waste of money) or G4/EU4 lters for regular operation.Panels in the indoor air section have a re- resistant (MO) aluminum foil-faced insulation. There is no more insulation paticules carried in the air. It can be cleaned which is paricuarly interesting for restaurant applications. All our drain pans are sloped. We thus avoid water stagnation that engenders corrosion and micro- organism life such as mold and fungi. TD5 service and diagnostic user display 5 display allows you to view data and make operational changes on Voyager rooftop equipped with Reliatel control v3.4 or above. 5 is a 5” (127mm diagonal) high resolution color touch screen display 5 provides in 26 languages: 15 different reports (3 custom, 12 standard), 12 differents graphs (4 custom, 8 standard) View and reset Historic of last 100 detailed alarms. Graph data can be exported to an excel le through USB memory stick. Figure 7 Downfl ow And Horizontal Economizers Economizers come with a comparative enthalpy control. Trane Communication Interface or TCI-R is available factory installed. This module when applied with the Micro easily interfaces with Trane’s Integrated Comfort TM System. Trane Modbus Communication Interface (PIC) is an accessory that interfaces with the third party Modbus protocol communicating systems. Lon ® Communication Interface (LCI) This is an electronic board mounted on the main control panel. It is needed to allow communication on a LonTalk ® Network at the unit level. Numerous options and accessories are available, such as: Adjustable roof curb Economizer Electric heater Hot water coil Black epoxy n coating CO 2 sensor Fused disconnect switch Smoke detector Firestat Supply fan soft starter On dual fuel units (DKD/DKH) Reliatel automatically selects the best source of heat. In low ambient operation, when mechanical heating is not delivering enough performance, the compressor switches off and the gas burner delivers the neede heat in an optimized conditions. This result in an optimized energy consumption, and higher compressor life cyle. The unit is equipped in standard with phase reversing protection preventing reverse rotation operation on compressors and other unit motors. Features and Benefi ts

CO 2 sensor OOOOOOOOHygienic control of the air.Works with the 0-50% motorized hood or the economizer and brings fresh air (modulating between the permanent fresh air setpoint and 50% of the nominal airfl ow) whenever the CO2 concentration in the room meets or exceeds the adjus- table threshold. The sensor itself has to be mounted in a relevant place in the room or in the ductwork.0-25% manual hood, not recom- mended with remote potentiometer. Exhaust fansO-O-O-O-To minimize overpressure in the building caused by the introduction of fresh air, when the economizer fresh air damper set at 40-50% OA (permanent value), and/ or when the pressure drop in the return duct is between the building overpressure accep- ted by the customer (12-25 Pa) and 200 Pa (maximum fan static pressure). When the exhaust fans are off, the gra- vity dampers open with increased buil- ding pressure to relieve the air pressure. When the exhaust fans are on, around 50% of airfl ow can be exhausted, depen- ding on the pressure drop of the return. They turn on whenever the position of the economizer fresh air dampers meet or exceed the power exhaust setpoint (when the supply fan is on). 0-50% motorized fresh air damper HEATING DEVICES Hot water coilO-O-----Need of heating or additional heating on cooling only units or heat pump units.
