Micro
•
The function of the Micro replaces the
need for field installed anti-short-
cycle timer and time delay relays. The
Micro ensures that these controls are
integral to the unit. The contractor no
longer has to purchase these controls
as options and pay to install them.
•
The wiring of the low voltage connec-
tions to the unit and the zone sensors
is as easy as 1-1, 2-2, and 3-3. This
simplified system makes it easier for
the installer to wire.
Serviceability
Today's owners are more conscious
of the cost of service and mainte-
nance. 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 up to 42%
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
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.
Features
and Benefits
•
One Zone Sensor option has central
control panel lights which indicate
the mode the unit is in and possible
diagnostic information (dirty filters
for example).
Standardized Components
•
Components are placed in the same
location for all Voyager units.
Familiarize yourself with one
Voyager and you are familiar with
all Voyager units.
•
One single Unitary Control Proces-
sor (UCP) can fit all Voyager
Packaged Gas/Electrics, Cooling
with Electric Heat, and Heat Pump
models. This provides standardiza-
tion of parts for the contractors.
Less money is tied up in inventory
using the Micro.
•
Contractors/owners can stock fewer
parts due to standardized compo-
nents throughout Voyager units. For
example, on the 3-7½ ton units
there is one combustion blower for
the high heat models and one for
the low heat models.

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.
Single Side Service
Single side service is standard on
all Voyager 3-25 ton units.
Quick-Sess™ Panels On The 3-
7½ Ton Units
Remove one screw for access to
the standardized internal compo-
nents and wiring.
Quick-Access Panels On The
8½-25 Ton Units
Remove three or fewer screws for
access to the standardized internal
components and wiring.
Colored And Numbered Wiring
You save time and money tracing
wires and diagnosing the unit.
Quick-Adjust Idler Arm
On all 8½-25 ton units, the belt and
sheaves can be quickly adjusted
without moving the mounted fan
motor. This is done with our idler
arm pulley. The Quick-Adjust Idler
Arm is a major savings of time and
money.
Single Point Power
A single electrical connection
powers the unit.
