Complete VAV Control Offering
All VariTrane VAV controls are factory
commissioned. This means that
airflow, temperature setpoints, and
addressing are performed in a
controlled factory environment. 100%
factory-run testing is included to
ensure that units arrive and function
properly upon job startup. With factory-
commissioned controls, you have
better control over cost and quality.
This results in a higher quality
installation at a lower cost.
Trane Factory-commissioned Controls
Include:
 DDC controller, the VAV Unit Control
Module (UCM) — Optimized
performance and integration to Trane
Tracer system.
 Pneumatic controller — Field
configurable for reverse- or direct-
acting thermostats.
 Analog controller — Non-

Factory-Installation of Customer-
furnished Controls:
Some customers prefer to provide
their own controller to be installed in
our manufacturing facility. In these
cases, Trane will:
 Ensure compatibility with unit relays,
fuses, and transformer
 Install the controller, including piping
the pressure transducer to the Trane
flow ring
 Coordinate with the owners preferred
control vendor
The factory-installed controller option
has been available since the early
1990s. It provides unlimited controller
flexibility for building owners, and
should be considered when Trane
controls are not required.
Interlocking Panels –
Ruggedness and rigidity are
assured with Trane’s patent-
pending interlocking panel
construction. It creates
unmatched unit rigidity.
Air Valve – Designed to limit
inlet deformation and provide
consistent and repeatable
airflow across the flow ring.
Metal Encapsulated Edges –
All VariTrane Units are complete
with encapsulated edges to arrest
cut fibers and prevent erosion in
the airstream. This raises the bar
in the VAV industry.
