Choosing a Mounting Location

Mount the sensor indoors in a central location within the zone to be measured, away from doors, windows, vents, heaters, and outside walls that could affect temperature readings. The sensor should be at least four feet from the floor, and no higher than necessary to prevent tampering.

Mounting

1.Insert a screwdriver into the gap in the plastic on the bottom side of the sensor enclosure, and pry the front part of the enclosure away from the rear mounting plate. Pull the front away from the mounting plate until the top separates from the mounting plate.

2.Remove the punch outs above the wiring connectors so that the sensor cables can be run into the sensor enclosure (see Figure 1).

3.Use the pre-made holes to mount the plate on a junction box using the screws provided, or mount it against a wall or riser. Do not mount the plate upside down or sideways. The plate should be mounted with the terminal blocks toward the bottom.

4.If necessary, drill or cut a hole in the wall to allow the sensor cable to be run through the wall into the sensor’s terminal block.
