Unit Cabinet
The compact cabinet with rounded
corners takes up less room and is less
costly to ship. The beveled and ribbed top
is not only aesthetically pleasing, it is
designed to prevent water from pooling.
VariTrac
When Trane’s changeover VAV System
for light commercial applications is
coupled with Precedent, it provides the
latest in technological advances for
comfort management systems and can
allow thermostat control in every zone
served by VariTrac.
Ventilation Override Accessory
With the Ventilation Override Accessory
installed, the unit can be set to transition
to up to 3 different pre-programmed
sequences for Smoke Purge,
Pressurization, and Exhaust. The
transition occurs when a binary input on
the RTOM is closed (shorted). This would
typically be a hard wired relay output
from a smoke detector or fire control
panel. The ventilation override kit is
available as a field installed accessory.
Zone Sensors
Available in programmable, automatic
and manual styles.
Precedent offers ultimate flexibility. Units
are built to order in our standard
“shortest in the industry” ship cycle time.
Rigorous Testing
All of Precedent’s designs were
rigorously rain tested at the factory to
ensure water integrity.
Actual shipping tests were performed to
determine packaging requirements. Units
were test shipped around the country to
determine the best packaging. Factory
shake and drop tests were used as part
of the package design process to help
assure that the unit arrives at the job site
in top condition.
Rigging tests include lifting a unit into the
air and letting it drop one foot, assuring
that the lifting lugs and rails hold up under
stress.
We perform a 100% coil leak test at the
factory. The evaporator and condenser
coils are leak tested at 200 psig and
pressure tested to 450 psig.
All parts are inspected at the point of final
assembly. Sub-standard parts are
identified and rejected immediately.
Every unit receives a 100% unit run test
before leaving the production line to
make sure it lives up to rigorous Trane
requirements.
