quick install
1. Mount the sensor on a vertical wall, about 4½ feet above the oor, in a location
away from ventilation sources.
2. Ax the backplate to the wall.
3. Wire the device. Refer to wiring diagrams on page 2.
4. Install the cover.

is not covered under the factory warranty.
1. Locate the tab at the top of the sensor housing. Using only the minimum required
force, press this tab down and pull the cover outward from the top. Set the cover
aside.

6. Wire the backplate.
Current Output (2-Wire, 4-20mA)
3. Punch out wire opening in the backplate.
4. Position the backplate vertically on the wall, 4 ½ feet above the oor. Locate away
from windows, vents, and other sources of draft. If possible, do not mount on an
external wall, as this might cause inaccurate temperature readings.
5. Mount the backplate onto the wall using the screws provided.
Five screwholes available; use a minimum of two for secure mounti ng.

7. Install the sensor onto the backplate and use the switch to select voltage or current
output. Output selection must be correct before applying power to the sensor.
