Comfort Starts at the Source

Comfort starts with the Trane Light
Commercial Packaged Rooftop Line.

These impressive products carry the
Trane reputation for quality and
reliability, while offering loads of
options, including microprocessor
controls.

The Trane Light Commercial
Packaged Rooftop line features:

• Precedent™ 3 - 10 tons

• Voyager™ 12½ - 25 tons

These products provide tight,
accurate space temperature control
when paired with VariTrac™ and
Tracker™ system controls.

Simple but Sophisticated
Control

While the Tr a c k e r system is amazingly
simple to install and operate, it easily
handles complex control functions.

With Tracker, you have a single location
to:

• Set and change all temperatures

• Maintain schedules for each day of the
week or year (including holidays)

• Monitor and supervise multiple
rooftops and zoning systems

• Monitor HVAC system alarms and/or
diagnostic messages and have those
reported directly to you

• Monitor your building from a distance
with Tracker's internal built-in modem
and PC software.

• Control fans and lights using remote
add-on modules to receive inputs and
control outputs

Outstanding Comfort

Trane created the Light Commercial
Integrated Comfort™ System to give
customers the best in light commercial
building management.

Voyager, Precedent, Tracker, and VariTrac
zoning work with individual sensors to
intelligently manage temperature and

control air volume. No more baking in
some areas, while freezing in others.

• Energy Efficiency

Zoning and scheduling save money and
energy by reducing equipment runtime,
and allow the use of smaller capacity
units.

• Easy Installation and Operation

The system automatically configures at
start up, begins to provide comfort, and
awaits the customer’s own schedule.

• Indoor Air Quality

. . . Zoning for Comfort

Zoning with Multiple Units

The multiple HVAC unit method of
zoning gives each zone access to an
individual unit and sensor.

Zones are usually configured by floor,
wing, or by departments with similar
environment control needs.

Tracker provides superior zone control
over multiple conventional
programmable thermostats.

Delivers Comfort
From the Rooftop
to the Zone

Airside Zoning

One unit, multiple thermostats – that’s
airside zoning.

Airside zoning provides multiple zone
control using a single HVAC unit and
multiple zone dampers. An individual
space sensor controls each damper, or
group of dampers.

By combining sensors, dampers, and a
VariTrac Central Control Panel, the
VariTrac system provides individual
temperature and air volume control to
multiple zones from a single HVAC unit.

Through constant monitoring of zones,
the VariTrac system maintains optimum
comfort, ventilation, and energy
efficiency.

Combination Zoning

Combination zoning incorporates both
multiple and airside zoning methods.

Some buildings have multiple HVAC
units serving single areas and other
HVAC units which are zoned with
VariTrac dampers and space sensors.

Tracker can be the scheduler and
operator panel for multiple VariTrac
zoning systems and multiple stand-alone
HVAC units. In addition, Tracker can
support units without microprocessor
controls as well as other equipment,
such as lights and exhaust fans by using
input/output controllers.

VariTrac™
damper and digital zone sensor

VariTrac is zoning made simple. A single

HVAC unit controls multiple zones of
comfort, with an individual thermostat in
each zone. This is the easiest and most
cost effective way to achieve true
individual comfort.

Frequently Asked Questions

What are the advantages of buying HVAC and electronic controls from a

single source?

Having one company to deal with reduces the design and delivery variables. If problems arise

during commissioning or afterwards, there’s no question about whether it’s a control or

equipment issue.

How does zoning improve comfort?

Zoning provides heating or cooling in areas based on the comfort needs of building occupants in those

specific areas.

Will a zoning system be difficult to install and program?

Each of the system components is carefully designed to be easy to install. Control panel enclosures streamline the

work of wiring. The Trane system intelligently configures itself to operate with little additional programming.

Is zoning affordable for light commercial applications?

Yes. When compared to using programmable thermostats, a Trane unitary zoning system is price competitive and

delivers greater functionality.

Will the building staff be able to control the system?

The touch screen interface on Tracker makes it easy for occasional users to check or change settings.

How can the Trane Light Commercial Integrated Comfort System help hold the line on energy

costs?

Everyone is concerned about energy these days. Zoning saves money and energy in three ways. Zoning

runs HVAC units for a particular zone only when needed. It allows the system designer to use smaller

capacity units and still meet comfort requirements. Zoning can employ a demand limiting strategy

to reduce energy use during peak periods.

What about indoor air quality?

The Trane light commercial system meets ASHRAE 62.99 by performing DCV

(Demand Control Ventilation). The system monitors the CO2 levels in each zone

and modulates the CFM of outside air based on the most critical zone. The

benefits of proper ventilation include fresh air for the occupants and

reduced operating costs when the space is occupied.
