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.

5RT-PRC001-EN

Features and Benefits

Drum and Tube Heat Exchanger

• The heat exchanger is manufactured

using aluminized steel with stainless steel components for maximum durability. The requirement for cycle testing of heat exchangers is 10,000 cycles by ANSI Z21.47. This is the standard required by both UL and AGA for cycle test requirements. American Standard requires the design to be tested to 2½ times this current standard. The drum and tube design has been tested and passed over 150,000 cycles, which is over 15 times the current ANSI cycling requirements.

• The negative pressure gas valve will

not allow gas flow unless the combustion blower is operating. This is one of our unique safety features.

• The forced combustion blower supplies

pre-mixed fuel 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 flame. The design is cycle tested at the factory for quality and reliability.

• Our gas/electric rooftops exceed all

California seasonal efficiency requirements and perform even better than the California NOx emission requirements.

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.

9RT-PRC001-EN

Application Considerations

Application of this product should be within the cataloged airflow and cooling considerations.

Low Ambient Cooling

This Voyager line features, as standard, low ambient cooling down to 0°F. The Voyager™ line features, with ReliaTel™ microprocessor controls, low ambient cooling down to 0°F. The following options need to be included/considered when low ambient applications are required: continuous fan operation, crankcase heaters, thermal expansion valves, frostat. Contact your local Trane Representative for more assistance with low ambient cooling applications.

Barometric Relief

This product offers an optional barometric relief damper included in the downflow economizer accessory. This accessory consists of gravity dampers which open with increased pressure. As the building air pressure increases, the pressure in the unit return air section also increases, opening the dampers and relieving the conditioned space.

NOTE: THE EFFECTIVENESS OF BAROMETRIC RELIEF DAMPER DURING ECONOMIZING OPERATION IS SYSTEM RELATED. PRESSURE DROP OF THE RETURN AIR SYSTEM SHOULD BE CONSIDERED TO CONTROL BUILDING PRESSURIZATION.

Heating Operation

The heat exchanger is manufactured with aluminized steel. To prevent condensation within the heat exchanger, do not exceed 50% outside air.

Power Exhaust Accessory

The power exhaust accessory is available on all 12½-25 tons downflow units. This accessory can be field installed and will assist in relieving building pressurization.

Condensate Trap

The evaporator is a draw-thru configuration. A trap must be field provided prior to start-up on the cooling cycle.

Clearance Requirements

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.

RT-PRC001-EN10

Selection Procedures

Cooling Capacity

Step 1 — Calculate the building’s total

and sensible cooling loads at design conditions. Use the Trane calculation form or any other standard accepted method.

Example: The following are the building requirements: a. Electrical Characteristics: 460/60/3 b. Summer Design Conditions: Entering

Evaporator Coil: 80° DB/ 67° WB

Outdoor Ambient: 95° DB c. Total Cooling Load: 220 MBh d. Sensible Cooling Load: 140 MBh e. Airflow: 8000 cfm External Static

Pressure: 0.450 in wg f. downflow configuration g. economizer

Step 2 — As a starting point, a rough determination must be made of the size of the unit. The final selection will be made after examining the performance at the given conditions. Divide the total cooling load by the nominal BTUH per ton (12 MBh per ton); then round up to the nearest unit size.

220 MBh / 12 MBh = 18.333 (approx 20 tons).

Step 3 — Examine gross capacity: Table PD-4 shows that a YC*240B3 has a gross cooling capacity of 246 MBh and 176 MBh sensible capacity at 95 DB ambient and 8000 cfm with 80 DB/ 67 WB air entering the evaporator.

To Find Capacity at Intermiediate Conditions Not in the Table

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 the unit will have enough capacity to meet the building requirements by determining the net capacity, which includes heat generated by the fan. In order to select the correct unit, the fan motor heat must be deducted from the gross coolingcapacity. 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 external static pressure to the additional static created by the added features:

External Static (duct system) 0.45 wg

Standard Filter 2 in. (from Table PD-36)

0.11 g

Economizer (100% Return Air from Table PD-20) 0.05 wg

Total static pressure 0.61

Note: The Evaporator Fan Performance Table PD-20 has already accounted for the pressure drop for standard filters and wet coils (see note below Table PD-20). Therefore the actual total static pressure is 0.61-0.11 = 0.50 wg.

With 8000 cfm and 0.50 inches external static pressure. Table PD-20 shows 3.96 bhp for this model. At these conditions, the note below the table gives a formula to calculate Fan Motor Heat:

3.15 X bhp = MBh

3.15 X 3.96 = 12.47 MBh.

Subtracting the fan motor heat from the gross cooling capacity of the unit: Net Total Cooling Capacity = 246 MBh - 12.47 = 251.53 MBh Net Sensible Cooling Capacity = 176 MBh - 12.47 = 163.53 MBh.

Since the Net Total Cooling Capacity meets the cooling load requirements of 220 MBh, we are satisfied with this selection.

Heating Capacity

Step 1 — Calculate the building heating

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

Step 2 — Size the system heating capacity to match the calculated building heating load. The following are building heating requirements: a. Total heating load of 165 MBh b. 8000 cfm c. Fuel - Natural gas

For the YC*240B3, there are two heating capacities available, 250 MBh and 400 MBh input models shown in Table PD-35. The output capacities of these furnaces are 175 MBh and 300 MBh respectively. The low heat model with 175 MBh best matches the building requirements, indicating a YC*240B3 should be selected.

Air Delivery Selection

External static pressure drop through the air distribution system has been calculated to be 0.50 inches of water. Enter Table PD-20 for a YC*240B3 at 8000 cfm and 0.50 static pressure. The standard motor at high speed will give the desired airflow.

Accessory Selection

Select accessories needed to accommodate the application.

Since reheat adds only sensible heat, follow the psychrometric chart to find the new wb temperature.

≅ 58.7°F

Consider Chart C-1. If the space relative humidity is equal to or above the space relative humidity setpoint, the Dehumidification option will:

• Energize compressor or both compressors (2 stage compressor units).

• Hot gas reheat valve is energized and hot gas is diverted to the reheat coil.

• Dehumidification/reheat is terminated when space humidity is reduced to 5% below relative humidity setpoint.

At MA’, air enters the RTU. The RTU filters, cools, and dehumidifies the air as it moves through the evaporator coil. Air leaves the evaporator coil saturated at the preset dew point condition (SA’) and is reheated by the hot gas reheat coil to deliver 71°F (SA) supply air to the space.
