Drywall Mounting (No Rough-in),
Typical
CAUTION:
Over-tightening may cause the
sensor base plate to crack or bend.
8. Feed the extra field wiring cable back through
the hole in the sensor base plate.
9. Snap the sensor pieces together by hooking the
feet of the base plate into the slots on the front
plate, then pushing the top of the sensor until it
snaps into place.
10. Tighten the sensor front retaining screw (See
Figure 1).
The installation is now complete.

Figure 1. Drywall Mounting (No Rough-in), Typical.
1. Using the sensor base plate as a template, mark
the center field wiring hole and the mounting
hole locations (See Figure 1).

0 to 10V or 4 to 20 mA.
NOTE: For drywall mounting, use only the top
and bottom holes.

2. Drill two 3/16-inch (4.8 mm) mounting holes.
Insert two plastic wall anchors into the holes for
the mounting screws.
3. Cut a 1-inch (25 mm) center hole with a hole
saw.
4. Pull about 6 inches (150 mm) of the field wiring
cable through the hole in the wall and insert
through the back of the sensor base plate.
5. Secure the field wiring in the terminal block
located on the printed circuit board.
6. Push the field wiring cable through the hole in
the wall and loosely mount the sensor base
plate on the wall using the screws provided. Do
not tighten the screws.
* Power requirements for these devices is 20 to 30 Vdc.
NOTE:
The override and passive temperature outputs are
isolated circuits. To reduce wiring, you may jumper
pins 3 and 2 or pins 5 and 2; however, the inputs
on your controller must be referenced to the same
ground that is powering the sensor.
7. Level the sensor base plate for appearance and
then tighten the mounting screws.
