Trane Communication Interface (TCI)
The TCI is available factory or field
installed. When applied with ReliaTel, this
module easily interfaces with the Trane
Integrated Comfort™ System.
Interoperability with LonTalk® (LCI-R)
The LonTalk Communication (LCI-R) for
Voyager Commercial offers a building
automation control system with
outstanding interoperability benefits.
LonTalk, which is an industry standard, is
an open, secure and reliable network
communication protocol for controls,
created by Echelon Corporation and
adopted by the LonMark Interoperability
Association. It has been adopted by
several standards, such as: EIA-709.1, the
Electronic Industries Alliance (EIA) Control
Network Protocol Specification and ANSI/
ASHRAE 135, part of the American
Society of Heating, Refrigeration, and Air-
Conditioning Engineer's BACnet control
standard for buildings.
Interoperability allows application or
project engineers to specifiy the best
products of a given type, rather than one
individual supplier's entire system. It
reduces product training and installation
costs by standardizing communications
across products.
Interoperable systems allow building
managers to monitor and control
Voyager Commercial equipment with a
Trane Tracer Summit™ or a 3rd party
building automation system.
It enables integration with many different
building controls such as access/intrusion
monitoring, lighting, fire and smoke
devices, energy management, and a
wide variety of sensors for temperature,
pressure, humidity and occupancy CO

Variable Frequency Drives (VFD)
Variable Frequency Drives are factory
installed and tested to provide supply fan
motor speed modulation. VFD's, as
compared to inlet guide vanes or
discharge dampers, are quieter, more
efficient, and are eligible for utility
rebates. The VFD's are available with or
RT -PRC007-EN
Features and
Benefits
without a bypass option. Bypass control
will simply provide full nominal airflow in
the event of drive failure.
VariTrac™ changeover-bypass VAV
For light commercial applications, Trane
offers constant volume (CV) Voyager
Commercial models with a changeover-
bypass VAV system.
For the most advanced comfort
management systems, count on Trane.
Delivered VAV
Trane provides true pressure
independent variable air volume with
Voyager Commercial delivered VAV. The
system is auto-configured to reduce
programming and set-up time on the job.
Generally available only on sophisticated
larger models, this Voyager Commercial
system can economically handle comfort
requirements for any zone in the facility.

The system consists of:
• Voyager™ Commercial VAV packaged
rooftops
• Up to 32 VariTrane™ VAV boxes with
DDC (direct digital controls)
• VariTrac™ Central Control Panel (CCP)
with Operator Display (OD)
The VariTrac Central Control Panel acts as
a communications hub by coordinating
the actions of the VAV rooftop and the
VAV boxes. Single duct or fan powered
VAV boxes are available, along with an
option for factory-installed local heat. For
more details, see VAV-SLM003-EN.
Downflow and Horizontal Economizers
The economizers come with three control
options dry bulb, enthalpy and differential
enthalpy. (Photo below shows the three
fresh air hoods on the Horizontal
Discharge Configuration).
