Siemens Series 2300 Installation Instructions Manual
Series 2300 Room Units
for TALON® Controllers
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:
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.

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.
