This valuable informationhelped to design a product that would getthe serviceman off the job quicker andsave the owner money.

5 Voyager doesthis by offering:Quality and ReliabilityReliaTel Controls (LCI-R)ReliaTel controls provide unit control forheating, cooling and ventilating utilizinginput from sensors that measure outdoorand indoor and Reliability are enhancedthrough ReliaTel control and logic: prevents the unit from short cycling,considerably improvingcompressor life. ensures that the compressor will runfor a specific amount of time whichallows oil to return for betterlubrication, enhancing the reliability ofthe with ReliaTel reduces thenumber of components required tooperate the unit , thereby reducingpossibilities for component Makes Installing andServicing EasyReliaTel eliminates the need for fieldinstalled anti-shortcycle timer and timedelay relays.

6 ReliaTel controls providethese functions as an integral part of theunit. The contractor no longer has topurchase these controls as options andpay to install wiring of the low voltage connectionsto the unit and the zone sensors is aseasy as 1-1, 2-2, and 3-3. This simplifiedsystem makes wiring easier for Makes Testing EasyReliaTel requires no special tools to runthe Voyager unit through its place a jumper between Test 1and Test 2 terminals on the Low VoltageTerminal Board and the unit will walkthrough its operational stepsautomatically. 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 long as the unit has power and the system on LED is lit, ReliaTel isoperational.

7 The light indicates that thecontrols are functioning features expanded diagnosticcapabilities when utilized with TraneIntegrated Comfort zone sensor options have centralcontrol panel lights which indicate themode the unit is in and possiblediagnostic information (dirty filters forexample).Other ReliaTel BenefitsThe ReliaTel built-in anti-shortcycle timer,time delay relay and minimum on timecontrol functions are factory tested toassure proper softens electrical spikes bystaging on fans, compressors Fallback is a benefit to thebuilding occupant.

8 If a component goesastray, the unit will continue to operate atpredetermined temperature Anticipation is a standardReliaTel feature. It functions continuouslyas ReliaTel and zone sensor(s) worktogether in harmony to provide muchtighter comfort control than conventionalelectro-mechanical same ReliaTel Board fits all VoyagerPackaged Gas/Electrics, Cooling withElectric Heat, and Heat Pump provides standardization of parts forcontractors. Less money is tied up ininventory with RT-PRC001-EN6 Features andBenefitsDrum and Tube Heat Exchanger The heat exchanger is manufacturedusing aluminized steel with stainlesssteel components for maximumdurability.

9 The requirement for cycletesting of heat exchangers is 10,000cycles by ANSI This is thestandard required by both UL and AGAfor cycle test requirements. AmericanStandard requires the design to betested to 2 times this currentstandard. The drum and tube design hasbeen tested and passed over 150,000cycles, which is over 15 times thecurrent ANSI cycling requirements. The negative pressure gas valve willnot allow gas flow unless thecombustion blower is operating. This isone of our unique safety features. The forced combustion blower suppliespre-mixed fuel through a singlestainless steel burner screen into asealed drum where ignition takes is more reliable to operate andmaintain than a multiple burner system.

10 The hot surface ignitor is a gas ignitiondevice which doubles as a safety deviceutilizing a continuous test to prove theflame. The design is cycle tested at thefactory for quality and reliability.
