Trane Precedent PKGP-PRC003-EN User Manual page 6

Outstanding Standard and
Optional Components
Black Epoxy Pre-Coated Coils
The pre-coated coils are an economical
option for protection in mildly corrosive
environments.
Cabinet Integrity
For added water integrity, Precedent has
a raised 1 1 / " lip around the supply and
8
return of the downflow units to prevent
water from blowing into the ductwork.
Clogged Filter/Fan Failure Switch
A dedicated differential pressure switch is
available to achieve active fan failure
indication and/or clogged filter indication.
These sensors allow a zone sensor
service light or Integrated Comfort
System to indicate a dirty filter or a fan
that's not working. The field installation
charges for these valuable feedback
devices often eliminate them from
consideration. Factory installation can
make such features a good investment.
CO Sensing
2
The CO sensor has the ability to monitor
2
space occupancy levels within the
building by measuring the parts per
million of CO (Carbon Dioxide) in the air.
2
As the CO levels increase, the outside air
2
damper modulates to meet the CO
space ventilation requirements. The CO
sensor kit is available as a field installed
accessory.
Colored And Numbered Wiring
Save time and money tracing wires and
diagnosing the unit.

Downflow And Horizontal Economizers
The economizers come with three control
options — dry bulb is standard, enthalpy
and differential enthalpy are optional.
Dual Thermistor Remote Zone Sensor
This sensor will reduce the total number
of remote sensors to obtain space
temperature averaging. This sensor
should be utilized with ReliaTel controls.
Foil-Faced Insulation
All panels in the evaporator section of the
unit have cleanable foil-faced insulation.
All edges are either captured or sealed to
ensure no fibers get into the airstream.
Factory Built Roof Curbs
Only two roof curbs for the entire
Precedent line simplifies curb selection.
