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.

Installation Instructions

September 10, 2009

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 sixposition terminal blocks, see Figure 3. For fourposition 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).

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.

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.

4. Pull the cable through the required mounting hardware in the order shown.

* Optional feature NOTE: 1. Some terminal blocks have only four terminal points.

2. Not all wires are used with all sensor models.

3. COM2 is the return signal path for the setpoint option.

4. Wiring configuration is only an example and can differ depending on application.

Sensor 544-780).

Figure 8. Electrical Box and Rough-in Mounting,

Typical.

5. Install the two sensor mounting screws provided but do not tighten.

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 sensor cable into the space.

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

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.

b. Tighten the two mounting screws to the

sensor base plate.

CAUTION:

Over-tightening may cause the sensor base plate to crack or bend.

7. Continue with Drywall Mounting (No Rough-in, Typical), Steps 7 through 13.

The installation is now complete.
