2.4 Mounting the Sensors
When planning a mounting location for the wall mount sensors, we recommend mounting one sensor
near the top of the drift or duct and the other sensor located near the bottom downstream from the
first on the opposite side, with an “imaginary line” between them intersecting the airflow at a typical
angle of 120 degrees.

Once the mounting brackets are installed, thread the sensors onto the mounts and align them at each
other using the pan/tilt adjustment on the bracket.
2.5 Connecting the Sensor Cables
A common mistake made is improperly installing the sensor cables. These must be threaded all the way
to ensure proper functionality.
