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.

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.

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.

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.

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.

available as a field installed 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.
