quick install

1. Mount the sensor on a vertical wall, about 4½ feet above the oor, in a location away from ventilation sources.

2. Ax the backplate to the wall.

3. Wire the device. Refer to wiring diagrams on page 2.

4. Install the cover.

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.
