Single Zone VAV is designed for use in single zone applications like gymnasiums, auditoriums,

manufacturing facilities, retail box stores, and any large open spaces, where there is a lot of

diversity in the load profile. Single Zone VAV (SZ VAV) is an ideal replacement to "yesterday's"

constant volume (CV) systems, by reducing operating costs while improving occupant comfort. SZ

VAV systems combine Trane application, control and system integration knowledge to exactly

match fan speed with cooling and heating loads, regardless of the operating condition. Trane

algorithms meet/exceed ASHRAE 90.1- 2010, SZ VAV energy-saving recommendations, and those

of CA Title 24. The result is an optimized balance between zone temperature control and system

energy savings. Depending on your specific application, energy savings can be as much as 20%.

Note: Building system modeling in energy simulation software like TRACE is recommended to

evaluate performance improvements for your application.

SZ VAV is fully integrated into the ReliaTel Control system and is available today. It provides the

simplest and fastest commissioning in the industry through proven factory-installed, wired, and

tested system controllers. All control modules, logic and sensors are factory installed, and tested

to assure the highest quality and most reliable system available. This means no special

programming of algorithms, or hunting at the jobsite for sensors, boards, etc. that need to be

installed in the field. Single Zone VAV is a quick and simple solution for many applications and is

available from your most trusted rooftop VAV system solution provider- Trane.

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 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 Packaged Gas/Electric, Cooling, and Heat Pump models. This

provides standardization of parts for contractors. Less money is tied up in inventory with ReliaTel.

Rigorous Testing

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

units incorporate either a one piece top or the Trane-Tite-Top (T3). Each 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.

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. All coils are pressure and leak tested at a minimum

of 450 psig. The completely assembled refrigerant system is leak tested at a minimum of 240 psig

with a refrigerant and nitrogen mixture.

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

immediately. Every unit receives a 100 percent unit run test before leaving the production line to

make sure it lives up to rigorous Trane requirements.

Application Considerations

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

Low Ambient Cooling

This Voyager line features, as a standard, low ambient cooling down to 0°F. Contact your local Trane

Representative for more assistance with low ambient cooling applications.

Barometric Relief

This product line 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.

Important: 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.

Power Exhaust Accessory

The power exhaust accessory is available on all downflow units. This accessory can be field

installed and will assist in relieving a building’s 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.

VariTrac

Varitrac is not recommended for SZ VAV and Multi-speed indoor fan applications.

PKGP-PRC012M-EN 17

Selection Procedure

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.

Step 2

Given the following 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: 172 MBh

D. Sensible Cooling Load: 122 MBh

E. Airflow: 6000 cfm

F. External Static Pressure: 0.50 in. w.g.

G. Rooftop - downflow configuration.

H. Accessories, Economizer, Supplementary Electric Heat

I. Heating Capacity 100 MBh

460 volt/3 phase Electric Supplemental Heat - at 6000 cfm

Size the equipment using Table 3, p. 24. 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 3, p. 24 shows that a WSD180E4 has a gross cooling capacity of 186.2 MBh and 138.9 MBh

sensible capacity at 95°F 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: 0.05 in. (from Table 12, p. 29)

Economizer Return Air: 0.04 in. (from Ta b l e 12 , p . 2 9 )

Electric Heater Size 18 kW: 0.06 in.

Total Static Pressure: 0.65 in.

Note: The Evaporator Fan Performance Table 6, p. 27 has already accounted for the pressure drop

for standard filters and wet coils.

18 PKGP-PRC012M-EN

Selection Procedure

Therefore, the actual Total Static Pressure is 0.65 - 0.05 = 0.6. With 6000 CFM and 0.60 inches,

Table 6, p. 27 shows 2.17 Bhp.

The note below Table 6, p. 27 gives a formula to calculate Fan Motor Heat:

3.15 x bhp = MBh

3.15 x 2.17 = 6.835 MBh

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

Net Total Cooling Capacity =

186.2 - 6.835 = 179.36 MBh

Net Sensible Cooling Capacity =

138.9 - 6.385 = 132.065 MBh

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 Tab l e 14 , p . 3 1 to match the heating loads at design conditions.

A. Total Heating Load: 100 MBh

B. Outdoor Ambient (Winter) 17 DB

C. Indoor Return Temperature: 70 DB

D . Airflow: 6000 CFM

Use the integrated portion of Table 14, p. 31 for the WSD180E4 to determine capacity at winter

design conditions. The mechanical heating portion of the heat pump will provide 85.4 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.

100.0 - 85.54 = 14.46 MBh

From Table 17, p. 32, at 480 volts, the 18 kW Heater will be adequate to do the job.

18 kW 61 MBh

From Table 17, p. 32 select heater AYDHTRK418A (18 kW 460/60/3).

nominal CFM and 0.35 inch ESP. To obtain net heating at other conditions, subtract fan heat at this condition and add fan heat at new

condition.

2. Heating capacities and powers are integrated to include the effects of defrost in the frost region.

3. All heating capacities and power (kW) are at 70% OD relative humidity.
