Series 2300 Room Units
for TALON® Controllers
Item Number 129-479, Rev. HA
Page 1 of 6
Product Description
These room units measure temperature in the
occupied space in which they are installed. Models
with display allow users to view the measured
temperature value. A version with temperature
setpoint adjustment is also offered.
These devices are intended for use with appropriate
signal input on a TALON Controller. The effective
sensing and setpoint range is 55°F to 95°F (13°C to
35°C).
These room units can be mounted on electrical
boxes, stud-type mounting brackets, or drywall.
Obtain the necessary mounting hardware and follow
the appropriate mounting procedures for the type of
installation required.

Mounting Information
Always mount the room unit vertically.
Locate the room unit:
•according to design specifications and local
regulations.
•where the air circulates around it freely (not
in recessed areas or behind doors).
•allowing a minimum of 4 inches (10 cm) free
space above and below for proper airflow,
the front cover removal tool, and the
computer communication cable.
•away from drafts caused by doors, windows,
outside walls, air registers, pipes, return air
plenums, etc.
•away from heat sources such as strong
lights, fireplaces, direct sunlight, etc.
•on an inside wall (preferably), about 5 feet
(1.5 m) above the finished floor.
Drywall Mounting (No Rough-in),
Typical
Base Plate Mounting and Wiring
1. Mark the center (cable) hole and the mounting
hole locations, using the room unit base plate as
a template. See Figure 2.
2. Drill two 3/16-inch (4.8 mm) mounting holes and
mount the two plastic wall anchors flush to
below the wall surface for stable mounting of the
device.
3. Cut a 1-inch (25 mm) center hole with a hole
saw.
4. Pull about three inches (75 mm) of the cable
through the hole in the base plate.
5. Mount the room unit base plate on the wall,
noting the UP arrow:
NOTE: If required, position the Back Plate
behind the Room Unit Base, aligning
the top and bottom mounting holes,
prior to mounting to the wall:
a. Install the two mounting screws provided,
but do not tighten.
b. Level the room unit base plate for
appearance.
c. Tighten the two mounting screws to the
room unit base plate.
d. Cut the cable, leaving about three inches
(75 mm) on the room unit side of the
drywall. Ensure that pin Number 1 connects
to the same wire at each end of the cable.
Figure 2. Drywall Mounting (No Rough-in), Typical.
7. Terminate the wires to the termination blocks on
the room unit's base plate. (See Figure 5.)
8. Feed the extra cable back through the hole.

Installation Instructions

1. If the device has a switch, determine if voltage
or current output is needed.
•For current, set the switch in the down
position (I).
•For voltage, set the switch in the up position
(V).
NOTE: The output setting applies to all
outputs (temperature, and setpoint).
2. If selecting voltage, set the jumper:
•Use the top and middle pins for 0-5V.
•Use the bottom and middle pins for 0-10V.
NOTE: If the jumper is missing or removed,
the output voltage will default to
0-10V.
NOTE: The factory default for displayed
temperature units is °F. To change the
display to °C, snip the wire jumper (0 Ohm
resistor R64) on the back of the PCA.

9. Snap the room unit cover to the room unit base
plate by first hooking the room unit front to the
top latches, and then rotating the cover
downward until it latches.
10. Loosen the safety set screw at the bottom of the
base one or two revolutions to lock the cover to
the base. Be careful not to loosen too far as the
screw can be completely removed from the
base.
Electrical Box and Rough-in
Mounting, Typical
1. If a locator is attached to the rough-in device,
remove the locator by removing the two screws
and lightly rocking the locator to pull it free.
2. Untie the twist tie and pull about three inches
(75 mm) of the room unit cable through the hole
in the base plate.
3. Mount the room unit base plate on the wall,
noting the UP arrow:
NOTE: If required, position the Back Plate
behind the Room Unit Base, aligning
the top and bottom mounting holes,
prior to mounting to the wall:
a. Install the two room unit mounting screws
provided, but do not tighten.
b. Level the room unit base plate for
appearance only.
c. Tighten the two mounting screws to the
room unit base plate.
CAUTION:
Over-tightening may cause the room unit
base plate to crack or bend.
4. Continue with Drywall Mounting (No Rough-in),
Typical, Steps 6 through 8, and Sensor Set-up.
CAUTION:
To prevent equipment damage, do the
following:
If room unit is powered by AC (See Figure
9):
•
A
C Supply must be type NEC Class 2 and
earth grounded at the secondary neutral.
•Room Unit ACN (GND) must be
connected to the controller common.
•If the controller has a floating common,
that common must be connected to the
same earth ground point as the controller
AC supply.
If room unit is powered by isolated DC
(See Figure 8):
•Where power is current limited up to 300
mA, it is not required to earth ground the
controller isolated common.
•Room Unit DC-(GND) must be
connected to the controller common.

Installation Instructions
November 13, 2012
CAUTION:
Follow manufacturer’s Installation
Instructions and Wiring Guidelines for
connecting the controller to the Room Unit.
•TALON Controllers with common
already earth grounded are TXIO used
on TC Modular and TC Compact 36
Expansion. These do not require the
earth ground wire to be connected to
the controller as shown in Figure 9.
•TALON Controllers with floating
common are TC Compact 16/24/36,
Raptor, Predator and PPM. These
require the earth ground wire to be
connected to the controller as shown in
Figure 9.
NOTE: If active temperature (0-5V/0-10V/4-20 mA) (Pin
3) rather than passive/ resistive temperature is
used, Passive Temp Common (Pin 6) does not
need to be terminated.
NOTE: To use the override function with a Predator
Controller, a 500 ohm resistor must be wired in
series with the setpoint termination on the
Predator Controller and the Override termination
8 on the Room Sensor. See Figure 6 and Figure
7for the complete wiring diagrams for the two
different style controllers.
The installation is now complete.
