Series 1000 Room Temperature
Sensors, 1K ΩPlatinum (375α) RTD
(MBC/RBC/MEC/UC)
Page 1 of 5
Product Description
These sensors work with the Modular Building
Controller (MBC), Remote Building Controller (RBC),
Modular Equipment Controller (MEC) and Unitary
Controller (UC). The sensors detect room
temperature using a 1K ΩPlatinum (375α)
Resistance Temperature Detector (RTD).
NOTE: These sensors 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
Locate the sensor:
•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 (100 mm)
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.
NOTE: While not recommended, if you must mount
the sensor on exterior brick or cement-type
walls, see Accessories.
Drywall Mounting (No Rough-in),
Typical
1. Mark the center (cable) hole and the mounting
hole locations using the sensor base plate as a
template. See Figure 2.
CAUTION:
For drywall mounting, only use the top
and bottom holes.
2. Drill two 3/16-inch (4.8 mm) mounting holes.
3. Cut a 1-inch (25 mm) center hole with a hole
saw.
4. If using screws to attach the sensor, insert two
plastic wall anchors.
5. Pull about three inches (75 mm) of the cable
through the mounting hardware in the order
shown. See Figure 2.
Figure 2. Drywall Mounting (No Rough-in), Typical.
6. Mount the sensor base plate on the wall, noting
the UP arrow on the stabilizer plate:
a. Install either the two mounting screws
provided, the drive rivets provided, or
spring clips, but do not tighten.
CAUTION:
Pounding too hard or over-tightening may
cause the sensor base plate to crack or
bend.
b. Level the sensor base plate for
appearance.
c. Tighten the two mounting screws to the
sensor base plate.
7. Cut the cable, leaving about 3 inches (75 mm)
on the sensor side of the drywall.
CAUTION:
For retrofits: Before cutting the cable,
make sure it is disconnected from the
UC/MBC/RBC.
8. Unplug the terminal block from the back of the
printed circuit board (PCB) and terminate the
cable wires at the sensor terminal block. For six-
position terminal blocks, see Figure 3. For four-
position terminal blocks, see Figure 4. Also see
Figure 5 (MBC/RBC) or Figure 6 (UC). Reinstall
the terminal block.

Figure 3. Terminating to Six-position Terminal Block
(with Setpoint Switch).
Figure 4. Terminating to Four-position Terminal Block
(No Setpoint Switch).
9. Feed the extra cable back through the hole in
the rubber insulator.
10. Snap the sensor front to the sensor base plate
by first hooking the sensor front to the bottom
latches, and then pushing the top of the sensor
front into place until it latches.
11. Tighten the sensor front retaining screw. See
Figure 2.
12. Terminate the other end of the wires either (a) at
the MBC/RBC module terminal block(s)
(Figure 5) or (b) at the appropriate UC terminal
blocks (Figure 6.)
The installation is now complete.
Terminating the Cable Wires
NOTE: 1. All connections for one sensor must be
terminated in the same cabinet, whether
MBC, RBC, MEC or UC.
2. Unitary Controller installations: On the
UC Input/Output Card, place the
universal inputs jumper in the RTD
position.

Full-featured Sensor 544-780).

4. Wiring configuration is only an example and can differ
depending on application. Figure 8. Electrical Box and Rough-in Mounting,
Typical.

Mounting, Typical
6. Mount the sensor base plate on the wall, noting
the "UP" arrow on the stabilizer plate:
a. Level the sensor base plate for appearance
only.
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. b. Tighten the two mounting screws to the
sensor base plate.
2. Untie the twist tie and pull about three inches
(75 mm) of the sensor cable into the space. CAUTION:
Over-tightening may cause the sensor
base plate to crack or bend.
3. If you have a single-sensor electrical box, install
the electrical box adapter plate. See Figure 8.
If you have a double-sensor electrical box,
install the required mounting plate(s).
If you use a universal adapter kit for a retrofit
job, install the multi-slotted plate in place of the
electrical box adapter plate. See Figure 8.
7. Continue with Drywall Mounting (No Rough-in,
Typical), Steps 7 through 13.
The installation is now complete.
