Operating Environment
The Performance Climate Changer™ air handler model
TCFS is a custom air handler engineered for your specific
indoor and outdoor applications. When considering the
placement of the air handler, it is important to consider the
operating environment. The acceptable ambient
temperature range for unit operation is -40ºF to 140ºF
(-40ºC to 60ºC).
For heating applications, a special motor may be required
to withstand the higher temperatures. Motors with Class B
insulation are acceptable for ambient temperatures up to
104º F, while motors with Class F insulation can withstand
ambient temperatures to +140º F (60º C).
Note:
Units with UL approval have a maximum ambient
temperature requirement of 104ºF. The customer
should provide adequate freeze protection for the
coils. See
“Routine Maintenance,” p. 63
for more
information.
Unit Description
The Performance Climate Changer custom TCFS air
handler is designed for a variety of controlled-air
applications. A typical unit consists of a fan, heating and/
or cooling coils, filters, and dampers. See unit submittals
for detailed descriptions.
Trane air handlers ship as complete assemblies or in sub-
assemblies if shipping splits are required. Some assembly
is required when the unit ships in subassemblies.
Your Trane sales team can make recommendations on
component selection based on pre-tested performance
data gathered in our labs, helping you to make a more
informed decision when designing your HVAC system.
Though not limited to pre-tested Trane components,
validated performance is available for many options,
including:
• Trane coils with high-efficient fin design to optimize coil
to the nearest fin-per-foot
• Coils with the best moisture carryover limits in the
industry
• Fans, including stacked, direct-drive plenum (SDDP™)
fans for fan array applications
• Traq™ airflow monitoring stations
• Energy recovery wheels
• Unit sound data based on ARI 260 tests
• Cool Dry Quiet (CDQ™) desiccant dehumidification
which breaks the dewpoint barrier using standard
equipment, and uses less energy than comparable
systems
• Trane catalytic air cleaning system (TCACS)
Years of research data help us accurately predict specific
unit performance for coils, casing, air leakage, thermal
performance, acoustics and energy recovery compliance.
Factory-Mounted Controls
Trane air handlers are available with a wide selection of
factory-mounted controls, including controllers, motor
starters, and variable frequency drives (VFD).
Most control components are mounted inside the unit.
Depending on the system configuration, this may include
damper actuators, dirty filter switches, averaging
temperature sensors, and low limit switches. VFDs,
starters, controllers, control transformers, static pressure
transducers, DC power supplies, and customer interface
relays will be in enclosures mounted on the inside of the
unit.
Small items that cannot be factory-mounted, such as
space temperature sensors, outside air temperature
sensors, and humidity sensors, will ship inside the control
enclosures, or packaged and shipped inside the fan or
mixing box section. Larger items are shipped inside the
fan section.
Note:
All control valves ship directly to the “ship-to
address” from the vendor unless another address
is given on the Trane sales order.
All factory-mounted control systems (controls that are
factory-wired to a unit controller or termination strip)
ordered without starters or variable-frequency drives
(VFDs) are provided with 120 to 24 Vac control
transformers mounted and wired in the auxiliary control
panel. The customer must provide 120 Vac control power,
50/60 Hz. A dedicated 15-amp circuit is recommended.
Factory-mounted control systems ordered with factory-
mounted starters or VFDs are supplied with line to 24 Vac
control transformers. No additional power wiring is
required.
Pre-Packaged Solutions for Controls
If the air handler has been selected using one of Trane’s
pre-packaged solutions options for controls, there are a
number of resources available to aid in commissioning
and start-up of the unit. These resources include
commissioning sheets, graphics and technical application
notes. The technical application notes include the control
sequencing, Trane Graphic Programming (TGP) and Rover
set-up files for the specific unit selected. These resources
are available through your local Trane sales office.
