Product Description
The Trane®programmable zone sensor (p/n X1379088401) can be used with UCP, Reliatel, and
IntelliPak control units. It has the following features:
• A liquid crystal display (LCD) with symbols for zone temperature, temperature setpoints,
system operating modes, day of the week, time of day, and occupancy settings
• Configurable to operate with constant-volume (CV) units, heat pump (HP) units, and variableair-volume (VAV) units
• System modes:
– CV: Heat, Cool, Auto, Off
– HP: Emergency Heat, Heat, Cool, Auto, Off
– VAV: Auto, Off
• A cooling setpoint range (occupied) of 45ºF to 98ºF (7.2ºC to 36.7ºC)
• A heating setpoint range (occupied) of 43ºF to 96ºF (6.1ºC to 35.6ºC)
• Two fan modes (CV and HP only): On, Auto
• A table of configurable functional options (see Tab l e 3 , p . 1 4 and Ta b l e 4 , p . 1 6 )
• Scheduling function: 7 days per week and up to 4 periods per day, occupied/unoccupied mode
• Temporary override function
• During occupied periods, an auxiliary relay rated for 1.25 A @ 30 Vac with one set of single-pole
double-throw contacts is activated.

Pre-Installation
This section provides the following pre-installation information:
• Location considerations
• Height requirements
• Mounting surfaces
• Recommended wire lengths
Location Considerations
Placement of the sensor is critical to proper operation. When selecting a location, avoid the
following:
• Areas of direct sunlight
• Areas in the direct airstream of air diffusers
• Exterior walls and other walls that have a temperature differential between the two sides
• Areas that are close to heat sources such as sunlight, appliances, concealed pipes, chimneys,
or other heat-generating equipment
• Drafty areas
• Dead spots behind doors, projection screens, or corners
• Walls that are subject to high vibration
• Areas with high humidity
• High traffic areas (to reduce accidental damage or tampering)
Height Requirements
It is recommended that you mount the back plate a maximum distance of 54 inches above the floor.
If a parallel approach by a person in a wheelchair is required, reduce the maximum height to 48
inches.
Note: Consult section 4.27.3 of the 2002 ADA (Americans with Disability Act) guideline, and local
building codes, for further details regarding wheelchair requirements.
Mounting Surfaces
Using the hardware provided, mount the back plate to a flat surface such as sheetrock or plaster,
or an electrical junction box. The sensor must be mounted plumb for accurate temperature control
and to ensure proper air movement through the sensor.
• If mounting onto sheetrock or plaster, use the plastic threaded anchors (pre-drilling holes is not
usually necessary) and the two M3.5 x 20 mm mounting screws.
• For mounting onto an electrical junction box, use the two 6-32 x 3/4 in. screws.
• If you are replacing a horizontally mounted sensor and need to cover an opening in the wall,
use the adapter kit (p/n BAYMTPL103A).

Note: The total resistance of these low voltage wires must not exceed 2.5 Ω/conductor. Any resistance greater than 2.5 Ω
may cause the control to malfunction due to an excessive voltage drop.

Installation
This section provides step-by-step installation instructions. Read through the pre-installation
information before proceeding with the installation.
Note: Before installing the sensor, ensure that:
• A wire access hole is available at the sensor location
• The wires are accessible through the hole
• The wires are attached to the appropriate unit controller
• There is continuity between the sensor location and the unit controller
• The wires are accurately labeled or identified by color
Mounting the Back Plate
WARNI NG
Hazardous voltage!
Disconnect all electric power, including remote disconnects before servicing. Follow proper
lockout/tagout procedures to ensure the power cannot be inadvertently energized. Failure to
disconnect power before servicing could result in death or serious injury.
NOTICE
Equipment damage!
Applying excessive voltage to the sensor will permanently damage it.
Note: Refer to the illustration below when installing the sensor.
1. Shut off power to the unit controller.
2. Remove the cover by firmly pressing the thumb tab at the bottom of the cover and pulling the
cover away from the back plate.
Note: If present, remove the security screw before removing the cover.
3. Determine the number of wires required by referring to Tab l e 2, p . 10 .
4. Feed the wires through the opening in the back plate.
5. Hold the back plate against the mounting surface and mark the screw locations.
6. Secure the back plate to the mounting surface using the included hardware.

NOTICE
Equipment damage!
Applying excessive voltage to the sensor will permanently damage it.
To wire the sensor to the unit controller (see guidelines for wire sizes and lengths in Table 1, p. 7.):
1. Ensure that the wires are connected to the appropriate
terminals at the unit controller.
2. Connect the wires to the terminal block (included in the hardware package with the sensor). See
Ta b l e 2 , p . 10 to determine where to terminate wires in the terminal block.
Note: The numbers on the terminal block correspond to the numbers on the terminals of the
unit controllers most frequently used with the sensor.
3. Attach the terminal block to the pins on the circuit board inside the sensor cover (Figure 1).
4. Push the excess wire into the wall cavity and plug it with nonflammable insulation to prevent
drafts from affecting the sensor.
Important: Do not coil excess wire inside the back plate.
