Features and Benefits

Single Zone VAV - One Zone Variable Air Volume Mode
Note: Single Zone VAV is designed to be used with a zone sensor. If a unit is configured for Single
Zone VAV operation but is connected to a thermostat, the control will revert to multi-speed
(2-Speed) indoor fan control. (See "Multi-Speed Indoor Fan System" above.)
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.

Stainless Steel Drain Pan
For excellent corrosion and oxidation resistance, the optional stainless steel drain pan provides a

CO2 Sensor - Demand Control Ventilation (DCV)
Demand-controlled ventilation (DCV) is a control strategy that responds to the actual demand
(need) for ventilation by regulating the rate at which the HVAC system brings outdoor air into the
building. A CO2 sensor measures the concentration (parts per million, ppm) of CO2 (Carbon
Dioxide) in the air. As the CO2 concentration changes, the outside air damper modulates to meet
the current ventilation needs of the zone. The CO2 sensor kit is available as a field installed
accessory. Two field installed kits are offered; C02 sensor and wiring or C02 sensor only. The C02
Sensor only kit should be ordered with factory installed C02 sensor wiring. Factory installed C02

product and technical support.

Outstanding Airflow Distribution
Airflow is outstanding. The Voyager can replace an older machine with old ductwork and, in many
cases, improve the comfort through better air distribution.

ReliaTel™ Controls Benefits
ReliaTel controls provide unit control for heating, cooling
and ventilating by utilizing input from sensors that
measure outdoor and indoor temperature.
Quality and Reliability are enhanced through ReliaTel
control and logic:
– Prevents the unit from short cycling, considerably
improving compressor life.
– Ensures the compressor will run for a specific
amount of time which allows oil to return for better
lubrication, enhancing the reliability of the
compressor.

Features and Benefits

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 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

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 Table 12, p. 29)
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.

PKGP-PRC012M-EN

17

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 Table 14, p. 31 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).

shall be cleaned, phosphatized, and finished with a weather-resistant baked enamel finish. Unit’s
surface shall be tested 500 hours in a salt spray test in compliance with ASTM B117. Cabinet
construction shall allow for all maintenance on one side of the unit. In order to ensure a water and
air tight seal, service panels shall have lifting handles and no more than three screws to remove.
All exposed vertical panels and top covers in the indoor air section shall be insulated with a 1/2 inch,
1 pound density foil-faced, fire-resistant, permanent, odorless, glass fiber material. The base of the
downflow unit shall be insulated with 1/2 inch, 1 pound density foil-faced, closed-cell material. The
downflow unit’s base pan shall have no penetrations within the perimeter of the curb other than
the raised 11/8 inch high supply/return openings to provide an added water integrity precaution,
if the condensate drain backs up. The base of the unit shall have provisions for forklift and crane
lifting.

Unit Top
The top cover shall be one piece, or where seams exist, double hemmed and gasket sealed to
prevent water leakage.

Filters
Two inch standard filters shall be factory supplied on all units. Optional two inch pleated MERV 8
and MERV 13 filters with filter removal tool shall be available.

Compressors
External high pressure cutout shall be provided on all 15 and 20 models. Low pressure switches
shall be standard. All units shall have direct-drive, hermetic, scroll type compressors with
centrifugal type oil pumps. Motor shall be suction gas-cooled and shall have a voltage utilization
range of plus or minus 10% of nameplate voltage. Internal overloads shall be provided with the
scroll compressors. Crankcase heaters shall be utilized with all scroll compressors.

Refrigerant Circuits
Each refrigerant circuit shall have independent fixed orifice or thermostatic expansion devices,
service pressure ports, and refrigerant line filter driers factory installed as standard. An area shall
be provided for replacement suction line driers.

Evaporator and Condenser Coils
Internally finned, 5/16” copper tubes mechanically bonded to a configured aluminum plate fin shall
be standard. Coils shall be leak tested at the factory to ensure the pressure integrity. All coils are
pressure and leak tested at 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 dual compressor
units shall have intermingled evaporator coils. Sloped condensate drain pans are standard. Patentpending 1+1+1 condenser coil, permanently gapped for easy cleaning is available.

The outdoor fan shall be direct-drive, statically and dynamically balanced, draw-through in the
vertical discharge position. The fan motor(s) shall be permanently lubricated and shall have builtin thermal overload protection.

Indoor Fan
Units above shall have belt driven, FC centrifugal fans with adjustable motor sheaves. Units with
standard motors shall have an adjustable idler-arm assembly for quick-adjustment of fan belts and
motor sheaves. All motors shall be thermally protected. Oversized motors shall be available for
high static application. All indoor fan motors meet the U.S. Energy Policy Act of 1992 (EPACT).

Controls
Unit shall be completely factory- wired with necessary controls and contactor pressure lugs or
terminal block for power wiring. Unit shall provide an external location for mounting a fused
disconnect device. ReliaTel controls shall be provided for all 24-volt control functions. The resident
control algorithms shall make all heating, cooling, and/or ventilating decisions in response to
electronic signals from sensors measuring indoor and outdoor temperatures. The control
algorithm maintains accurate temperature control, minimizes drift from set point, and provides
better building comfort. A centralized control shall provide anti-short cycle timing and time delay
between compressors to provide a higher level of machine protection.

Defrost Controls
Adaptive demand defrost shall be provided to permit defrost wherever coil icing conditions begin
to significantly reduce unit capacity.

Discharge Line Thermostat
A bi-metal element discharge line thermostat is installed as a standard option on the discharge line
of each system. This standard option provides extra protection to the compressors against high
discharge temperatures in case of loss of charge, extremely high ambient and other conditions
which could drive the discharge temperature higher. Discharge line thermostat is wired in series
with high pressure control. When the discharge temperature rises above the protection limit, the
bi-metal disc in the thermostat switches to the off position, opening the 24 VAC circuit. When the
temperature on the discharge line cools down, the bi-metal disc closes the contactor circuit,
providing power to the compressor. When the thermostat opens the fourth time, the ReliaTel
control must be manually reset to resume operation on that stage.

Phase Monitor
The Phase Monitor is a 3 phase line monitor module that protects against phase loss, phase
reversal and phase unbalance. It is intended to protect compressors from reverse rotation. It has
an operating input voltage range of 190-600 VAC, and LED indicators for ON and FAULT. There are
no field adjustments and the module will automatically reset from a fault condition.

Variable Frequency Drive
Variable Frequency Drives are factory installed and tested to provide supply fan motor speed
modulation. VFDs on the supply fan, as compared to inlet guide vanes or discharge dampers, are
quieter, more efficient, and are eligible for utility rebates. All VFDs are designed to allow bypass
if required. Bypass control will simply provide full nominal airflow in the event of drive failure.
