Factory-Mounted Controls - Trane Climate Changer T Series Installation Operation & Maintenance

General Information

Factory-Mounted Controls

The T-Series air handler is 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
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, typically
3 amps for unit sizes 3 to 57 and 5 amps for unit sizes 66 to 100. 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 T-Series 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.
