3200 Combination RH&T Room Units,

Product Description

These room units allow users to view and adjust
points in the controller using the room unit buttons
and digital display.

They work with various Terminal Equipment
Controllers (TECs) and Actuator Terminal
Controllers (ATECs) offered by Siemens Industry,
Inc. These devices incorporate a solid state or 10K
NTC sensing element to detect temperature (and
humidity for QFA models). 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, on a flat wall.
Locate the room unit:

• according to design specif i c ations and loc a l
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 hex bit or passkey 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, or per code
(ANSI, ADA, or local regulation).

4. Pull about three inches (75 mm) of the cable
through the hole in the base plate.

Drywall Mounting (No Rough-in),
Typical

1. Mark the center (cable) hole and the mounting
hole locations, using the room unit base pl ate 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.

NOTE: It is recommended that you use the

optional Insulating Gasket on the back
of the Sensor Base for hollow wall
installations.

When applying the adhesive-backed
gasket to the back of the Sensor Base,
orient the gasket so that the cut-out
arrow portion of the gasket is in the
upper lefthand quadrant of the Sensor
Base. The Sensor Base has an UP
arrow molded into the surface in the
same quadrant location.

NOTE: See Figure 2 for details on optional

Gasket application.

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.
