Serviceability
Today’s owners are more conscious of
the cost of service and maintenance.
Voyager was designed with input from
service contractors. Their information
helped us design a unit that would get
the serviceman off the job quicker and
save the owner money. Here is why
Voyager can save money in service.
Voyager’s Simpler Design
The Voyager design uses fewer parts
than previous units. Since it is simpler
in design, it is easier to diagnose.
Micro
•
The Micro 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, the Micro is
operational. The light indicates that the
Micro is functioning properly.
•
The Micro features expanded
diagnostic capabilities when utilized
with Trane’s 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).
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 timesaving
installation feature.
Value
Low Ambient Cooling
All Voyager Commercial units have
cooling capabilities down to 0°F
(-17.8°C) as standard.
Power Exhaust Option
Provides exhaust of the return air when
using an economizer to maintain
proper building pressurization. Great
for relieving most building
overpressurization problems.
Micro Benefits
•
The Micro in the Voyager units has
built-in anti-short-cycle timer, time
delay relay and minimum “on” time
controls. These controls are functions
of the Micro and are factory tested to
assure proper operation.
•
The Micro softens electrical “spikes” by
staging on fans, compressors and
heaters.
•
The Intelligent Fallback or Adaptive
Control 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
feature of the Micro. It functions
constantly as the Micro and zone
sensor work together in harmony to
provide tighter comfort control than
conventional electromechanical
thermostats.
