Features and Benefits
ReliaTel Control Logic Enhances
Quality and Reliability
—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, and Heat Pump models.
This provides standardization of
parts for contractors. Less money is
tied up in inventory with ReliaTel.
VariTrac – Building Automation
System
When Trane’s changeover VAV
System for light commercial
applications is coupled with Voyager,
it provides the latest in technological
advances for comfort management
systems and can allow thermostat
control in every zone served by
VariTrac.

Rigorous Testing
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
3
). 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.
