Features and Benefits

Easy to Install, Service and Maintain

Because today’s owners are very costconscious when it comes to service and maintenance, the Trane Voyager was designed with direct input from service contractors. This valuable information helped to design a product that would get the serviceman off the job quicker and save the owner money. Voyager does this by offering:

Quality and Reliability

ReliaTel™ Controls (LCI-R)

ReliaTel controls provide unit control for heating, cooling and ventilating utilizing input from sensors that measure outdoor and indoor temperature.

ReliaTel™

Quality and Reliability are enhanced through ReliaTel control and logic:

—prevents the unit from short cycling,

considerably improving compressor life.

—ensures that the compressor will run

for a specific amount of time which allows oil to return for better lubrication, enhancing the reliability of the compressor.

Voyager with ReliaTel reduces the number of components required to operate the unit, thereby reducing possibilities for component failure.

ReliaTel Makes Installing and Servicing Easy

ReliaTel eliminates the need for field installed anti-shortcycle timer and time delay relays. ReliaTel controls provide these functions as an integral part of the unit. The contractor no longer has to purchase these controls as options and pay to install them.

The wiring of the low voltage connections to the unit and the zone sensors is as easy as 1-1, 2-2, and 3-3. This simplified system makes wiring easier for the installer.

ReliaTel Makes Testing Easy

ReliaTel requires no special tools to run the Voyager 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 “system on” LED is lit, ReliaTel is operational. The light indicates that the controls are functioning properly.

ReliaTel features expanded diagnostic capabilities when utilized with Trane Integrated Comfort™ Systems.

Some zone sensor options have central control panel lights which indicate the mode the unit is in and possible diagnostic information (dirty filters for example).

Other ReliaTel Benefits

The ReliaTel built-in anti-shortcycle timer, time delay relay and minimum “on” time control functions are factory tested to assure proper operation.

ReliaTel softens electrical “spikes” by staging on fans, compressors and heaters.

Intelligent Fallback is a benefit to the building occupant. If a component goes astray, the unit will continue to operate at predetermined temperature setpoint.

Intelligent Anticipation is a standard ReliaTel feature. It functions continuously as ReliaTel and zone sensor(s) work together in harmony to provide much tighter comfort control than conventional electro-mechanical thermostats.

The same ReliaTel Board fits all Voyager Packaged Gas/Electrics, Cooling with Electric Heat, and Heat Pump models. This provides standardization of parts for contractors. Less money is tied up in inventory with ReliaTel.

Due to standardized components throughout the Voyager line, contractors/ owners can stock fewer parts.

Supply and/or Return Air Smoke Detector

With this option installed, if smoke is

detected, all unit operation will be shut down. Reset will be manual at the unit. Return Air Smoke Detectors require minimum allowable airflow when used

with certain models.

Tool-less Hail Guards

Tool-less, hail protection quality coil

guards shall be either factory or field-installed for condenser coil protection. This option protects the condenser coil from vandalism and/or hail damage.

Va riTra c

When Trane’s changeover VAV System for light commercial applications is coupled with Voyager, it provides the latest in technological advances for comfort management systems and can allow thermostat control in every zone served by VariTrac.

Ventilation Override Accessory

With the Ventilation Override Accessory installed, the unit can be set to transition to up to 3 different pre-programmed sequences for Smoke Purge, Pressurization, and Exhaust. The transition occurs when a binary input on the RTOM is closed (shorted). This would typically be a hard wired relay output from a smoke detector or fire control panel. The ventilation override kit is available as a field installed accessory.

Zone Sensors

Available in programmable, automatic and manual styles.

Rigorous Testing

The fan and idler arm assembly designs have been tested to over 300,000 cycles each. Our combined cycle testing is now over 7,000,000 cycles.

All of Voyager’s designs were rigorously rain tested at the factory to ensure water integrity.

Actual shipping tests were performed to determine packaging requirements. Units were test shipped around the country to determine the best packaging. Factory shake and drop tests were used as part of the package design process to help assure that the unit arrives at the job site in top condition.

Rigging tests include lifting a unit into the air and letting it drop one foot, assuring that the lifting lugs and rails hold up under stress.

We perform a 100% coil leak test at the factory. The evaporator and condenser coils are leak tested at 200 psig and pressure tested to 450 psig.

All parts are inspected at the point of final assembly. Sub-standard parts are identified and rejected immediately.

Every unit receives a 100% unit run test before leaving the production line to make sure it lives up to rigorous Trane requirements.

Voyager units incorporate either a one piece top or the Trane-Tite-Top (T part of the top (either two or 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.

Features and Benefits

Easy to Install and Service

Conversionless Units

The dedicated design units (either downflow or horizontal) require no panel removal or alteration time to convert in the field — a major cost savings during installation.

Horizontal units come complete with duct flanges so the contractor doesn’t have to field fabricate them. These duct flanges are a time and cost saver.

Easy Access Low Voltage Terminal Board

Voyager’s Low Voltage Terminal Board is external to the electrical control cabinet. It is extremely easy to locate and attach the thermostat wire. This is another cost and time saving installation feature.

Low Voltage Connections

The wiring of the low voltage connections to the unit and the zone sensors is as simple as 1-1, 2-2, and 3-3. This simplified system makes it easy for the installer to wire.

The recommended clearances identified with unit dimensions should be maintained to assure adequate serviceability, maximum capacity and peak operating efficiency. Actual clearances which appear inadequate should be reviewed with the local Trane sales personnel.

Unit Pitch

These units have sloped condensate drain pans. Units must be installed level, any unit slope must be toward access side of unit.

PKGP-PRC0 01-EN

Selection Procedures

Cooling Capacity

Step 1

Calculate the building’s total and sensible cooling loads at design conditions. Use the Tranecalculation form or any other standard accepted method.

Step 2

Given the following building requirements:

Electrical Characteristics: 460/60/3

Summer Design Conditions: Entering Evaporator Coil: 80 DB/ 67 WB Outdoor Ambient: 95 DB

Total Cooling Load: 172 MBh

Sensible Cooling Load: 122 MBh

Airflow: 6000 cfm

External Static Pressure: .50 in. w.g.

Rooftop - downflow configuration.

Accessories Economizer Supplementary Electric Heat

Heating Capacity 88 MBh 460 volt/3 phase Electric Supplemental Heat - at 6000 cfm

Size the equipment using Table PD-3. As a starting point, a rough determination of the size of the unit must be made. This selection will then be confirmed after examining the performance at the given conditions. Divide the total cooling load by nominal BTUH per ton (12 MBh per ton); then round up to the nearest unit size. 172 MBh/12 MBh = 14.33 (approx. 15 tons.)

Step 3

Table PD-3 shows that a WCD180B4 has a gross cooling capacity of 183.0 MBh and 129.0 MBh sensible capacity at 95 degree ambient and 6000 cfm with 80 DB/67 WB air entering the evaporator.

To Find Capacity at Intermediate Conditions

When the design conditions are between two numbers that are in the capacity table, interpolation is required to approximate the capacity.

Note: Extrapolation outside of the table conditions is not recommended.

Step 4

Verify that there will be enough capacity by determining net capacity. In order to select the correct unit which meets the building’s requirements, the fan motor heat must be deducted from the gross cooling capacity. The amount of heat that the fan motor generates is dependent on the effort by the motor cfm and static pressure. To determine the total unit static pressure, add the following:

External Static: 0.50 in.

Standard Filter 1 in: 0.11 in. (from table PD-13)

Economizer Return Air: 0.04 in. (from table PD-13)

Electric Heater Size 18 kW: .06 in.

Total Static Pressure: .71 in.

Note: The Evaporator Fan Performance Table PD-7 has already accounted for the pressure drop for standard filters and wet coils.

Therefore, the actual Total Static Pressure is .71 - .11 = .60. With 6000 cfm and .60 inches, Table PD-7 shows 2.66 Bhp.

The note below Table PD-7 gives a formula to calculate Fan Motor Heat:

3.15 x bhp = MBh

3.15 x 2.66 = 8.38 MBh

Now subtracting the fan motor heat from the gross cooling capacity of the unit:

Net Total Cooling Capacity =

183-8.38=170.62

Net Sensible Cooling Capacity=

129-8.38=120.62

Step 5

If the performance will not meet the required load of the building, try a selection at the next higher size unit.

Heating Capacity

Step 1

Calculate the building heating load using the Trane calculation form or other standard accepted method.

Step 2

Size the equipment using Table PD-16 to match the heating loads at design conditions.

Total Heating Load: 88 MBh

Outdoor Ambient (Winter) 17 DB

Indoor Return Temperature: 70 DB

Airflow: 6000 Cfm

Use the integrated portion of Table PD-16 for the WCD180B4 to determine capacity at winter design conditions. The mechanical heating portion of the heat pump will provide 45 MBh.

Step 3

Because 45 MBh is less than the building’s required heating capacity at winter design conditions, a supplementary heater must be selected.

88 MBh - 45 MBh = 43 MBh

From Table PD-20, at 480 volts, the 18 kW Heater will be adequate to do the job.

18 kW 61 MBh

From Table ED-3 select heater AYDHTRK418A (18 kW 460/60/3).

Controls

Field Installed Control Options

Zone Sensors

Zone sensors are the building occupant’s comfort control devices. They replace the conventional electro-mechanical thermostats. The following zone sensor options are available for Voyager units with the ReliaTel™ control:

Manual Changeover

Heat, Cool or Off System Switch. Fan Auto or Off Switch. One temperature setpoint lever.

Manual/Automatic Changeover

Auto, Heat, Cool or Off System Switch. Fan Auto or Off Switch. Two temperature setpoint levers. Optional Status Indication LED lights, System On, Heat, Cool, or Service.

Remote Sensor

Sensor(s) available for all zone sensors to provide remote sensing capabilities.

Dual Thermistor Remote Zone Sensor

This sensor will allow the customer to reduce the total number of remote sensors to obtain space temperature averaging. This sensor should be utilized with ReliaTel controls.

Digital Display Zone Sensor

The Digital LCD (Liquid Crystal Display) zone sensor has the look and functionality of standard zone sensors. This sensor includes a digital display of set point adjustment and space temperature in F (Fahrenheit) or C (Celsius). Includes FAN and SYSTEM buttons (supports the service functions of the standard sensor). E-squared memory stores last programmed set points. Requires 24 VAC (Volts AC). This sensor should be utilized with ReliaTel™ controls.

Programmable Night Setback

Auto or manual changeover with sevenday programming. Keyboard selection of

Heat, Cool, Fan, Auto, or On. All programmable sensors have System On, Heat, Cool, Service LED/indicators as standard. Night Setback Sensors have one (1) Occupied, one (1) Un-occupied, and two (2) Override programs per day.

Integrated Comfort

System

Sensor(s) available with optional temperature adjustment and override buttons to provide central control through a Trane Integrated Comfort

system.

CO2 Sensing

The CO has the ability to

sensor

monitor space occupancy levels within the building by measuring the parts per million of CO

(Carbon

Dioxide) in the air. As the CO increase, the outside air damper

levels

modulates to meet the CO2 space ventilation requirements. The CO kit is available as a field installed

sensor

accessory.

Economizer Controls

The standard equipment offering is a fixed dry bulb changeover control. In addition, there are two optional controls, Enthalpy and Differential Enthalpy Control.

Enthalpy Control

Replaces the dry bulb control with a wet bulb changeover controller which has a fully adjustable set point. Enthalpy control offers a higher level of comfort control, along with energy savings potential, than the standard dry bulb control. This is due to the additional wet bulb sensing capability.

Differential Enthalpy

Replaces the standard dry bulb control with two enthalpy sensors that compare total heat content of the indoor air and outdoor air to determine the most efficient air source. This control option offers the highest level of comfort control, plus energy efficiency, available.

Remote Potentiometer

Minimum position setting of economizer can be remotely adjusted with this accessory.

Differential Pressure Switches

This factory or field-installed option allows individual fan failure and dirty filter indication. The fan failure switch will disable all unit functions and “flash” the Service LED on the zone sensor. The dirty filter switch will light the Service LED on the zone sensor and will allow continued unit operation.

Trane Communication Interface (TCI)

This factory or field-installed microprocessor interface allows the unit to communicate to Trane’s Integrated Comfort

system.
