Factory-installed Options
Economizer
Equipped with either dry bulb, reference
or comparative enthalpy sensing, this
feature provides free cooling as the
outdoor temperature and/or humidity
decreases. Economizers, correctly
installed, offer a valuable energy
savings. Factory-installed economizers
save time and ensure proper installation.
Trane Communication Interface
Available factory or field-installed. This
module when applied with ReliaTel™
easily interfaces with Trane's Integrated
TM
Comfort System.
Hinged Access Doors
These doors permit easy access to the
filter, fan/heat, and compressor/control
sections. They reduce the potential roof
damage from screws or sharp access
door corners.
Through the Base Electrical Utility
Access
Factory provided through the base
openings simplify wiring and piping.
Because these utility openings
frequently minimize the number of roof
penetrations, the integrity of roofing
materials is enhanced.
Unit Mounted Disconnect or Circuit
Breaker
Codes require a method of assured unit
shutdown for servicing. Field-installed
disconnects sometimes interfere with
service access. Factory installation of unit
disconnects reduces costs, assures
proper mounting and provides the
opportunity to upgrade to unit circuit
breaker protection.
Clogged Filter/Fan Fail Switches
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.

Dehumidification (Hot Gas Reheat)
Option
This option allows for increased outdoor
air ventilation. It reduces humidity levels
while increasing comfort level in the air
space. Cooling can operate without a
demand for dehumidification. The hot gas
reheat coil is designed to deliver
maximum reheat temperatures and
pivot to allow for easy access cleaning.
