Trane Dual-Duct is a versatile and efficient HVAC system that offers a range of benefits for commercial and industrial buildings. With its ability to independently control temperature and airflow in different zones, Dual-Duct provides precise and customized comfort for occupants.
Here are some of the key features and capabilities of Trane Dual-Duct:
- Zonal control: Dual-Duct allows you to divide your building into multiple zones, each with its own thermostat. This gives you the flexibility to set different temperatures in different areas, ensuring that everyone is comfortable.
- Independent airflow control: In addition to temperature control, Dual-Duct also provides independent control over airflow. This means you can adjust the amount of air that is circulated in each zone, ensuring that there is always enough fresh air without overcooling or overheating.

6. Sensor must be connected to a UCM and powered up for
at least 1 hour to achieve maximum accuracy.
7. “Sensor Setpoint”output can not be verified with an ohm
meter. Connection to a UCM is necessary to verify
operation.
8. Plug holes through the wall behind the sensor to prevent
undesirable airflow.

Pre-Installation Notes
1. All wiring must be in accordance with NEC and local
building codes.
2. Do not run low-voltage wiring in the same conduit with
high voltage power wiring.
3. Sharing the 24V Class 2-power source from the UCM is
the preferred practice and simplifies installation. See
wiring diagram above and wiring requirements under
Item 4 at right. Use caution to be sure 24V and GND are
connected to the proper terminals when connecting to
the UCM.
4. If a separate 24V Class 2 power source is used to power
the Digital Zone Sensor, terminals TB1-2 (24V GND) and
TB2-2 (Sensor GND) must be jumpered together at the
sensor for the sensor to operate. However, the use of a
transformer with a supply voltage of greater than 150V to
ground as the separate 24V Class 2 power source is not
recommended because its output should be grounded to
building ground (following NEC requirements for Class 2
devices). This additional grounding can affect the
operation and/or damage the Digital Zone Sensor.
5. The sensor display will not be enabled with 24V
connection only. Sensor signal wiring to the UCM must
be connected for the display to function.
Installation Instructions
1. Choose mounting location. Choose a spot on an
interior wall near the return air grille about five feet above
the floor. Air should circulate freely and be of average
temperature for the zone. Avoid areas such as:
y behind doors.
y on outside walls or walls facing uncontrolled areas.
y in direct sunlight or near sources of radiant heat that could
affect temperature measurement.
y in-line with discharge air from unit being controlled.
2. Remove cover. Remove zone sensor cover by easing the
tip of a small screwdriver into the top rear center slot
closest to the wall. Gently move the top of the screwdriver
towards you. Excessive force is not recommended for
cover removal!
3. Mount base. Remove zone sensor cover from base and
mount base on wall or 2 x 4 device box.
4. Connect wires. Connect wires as shown in the wiring
diagram. For wire lengths less than 75 feet, an 18 gage, 5
or 6 conductor cable may be used. For wire lengths
greater than 75 feet, use 18 gage, 2-conductor cable for
the power wiring (TB1), and 18 gage, 3 conductor
cable for signal wiring (TB2). Avoid routing wires near
sources of electrical noise such as motors, fluorescent
lights, LAN wiring, etc. In some high noise environments,
signal wires may require shielding. The communication
jack should be wired with the cable appropriate for the
system being installed.
5. Replace Cover. Place zone sensor cover back on the
base and snap securely into place.
WARNING
Hazardous Voltage!
Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures
to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in
death or serious injury.
