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.

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.

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.

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
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 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.
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.
Power Exhaust Accessory
The power exhaust accessory is available
on all 12½-25 ton 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-PRC002-EN

Selection
Procedures
Cooling Capacity
Step 1
Calculate the building’s total and sensible
cooling loads at design conditions. Use
the Trane calculation methods or any
other standard accepted method.
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
nominal BTUH per ton (12 MBh per ton);
then round up to the nearest unit size.
180 MBh / 12 MBh = 15.0 Tons
Step 3
Table PD - 2 shows that a TCD180B4 has a
gross cooling capacity of 184 MBh and
130 MBh sensible capacity at 6000 cfm
and 95 DB outdoor ambient with 80 DB,
67 WB air entering the evaporator.
To Find Capacity at Intermediate
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
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 you add the
external static pressure to the additional
static related by the added features:
External Static (duct system)
0.49 wg
Standard Filter 1 in.0.10 wg
from Table PD-35
Economizer0.04 wg
(100% Return Air) from Table PD-35
Electric Heater Size 36 kw 0.07 wg
from Table PD-35
Total Static Pressure0.60 wg
Note: The Evaporator Fan Performance
Table PD-18 has already accounted for
the pressure drop for standard filters and
wet coils (see note below Table PD-18).
Therefore, the actual total static pressure
is 0.60 -0.10 (from Table PD-35) = 0.50 wg.
With 6000 cfm and 0.50 wg.
Table PD-18 shows 2.56 bhp for this unit.
Note below the table gives a formula to
calculate Fan Motor Heat,
3.15 x bhp = MBH.
3.15 x 2.56 = 8.06 MBH.
Now subtract the fan motor heat from
the gross cooling capacity of the unit:
Net Total Cooling Capacity
= 184 MBH - 8.06 = 175.9 MBH.
If the performance will not meet the
required load of the building -total or
sensible cooling load, 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 system heating capacity to
match the calculated building heating
load. The following are building heating
requirements:
A
Total heating load of 115.0 MBH
B
6000 cfm
C
460 volt/3 phase Power Supply
The electric heat accessory capacities are
listed in Table PD-36. From the table, a 36
kw heater will deliver 122.94 MBH at 480
volts. In order to determine capacity at
460 volts, the heater voltage correction
factor from Table PD-37 must be used.
Therefore, 122.94 MBH x .94 (voltage
correction factor) = 115.6 MBH.
Air Delivery Selection
External static pressure drop through the
air distribution system has been
calculated to be 0.50 inches of water.
From Table PD-35 static pressure drop
through the economizer is 0.04 and the
36 kw heater is 0.07 inches of water (0.49
+ 0.04 + 0.07). Enter Table PD-18 for a
TCD180B4 at 6000 cfm and 0.50 static
pressure. The standard motor at 777 rpm
will give the desired airflow at a rated bhp
of 2.71.

• 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.
