Mounting
Determine the proper location of the Daylight
Sensor using the adjacent diagrams.
• The arrow on the Daylight Sensor defines the viewing
direction
• Place the daylight sensor so its viewing area is
centered upon the nearest window at a distance of
between 1-2 H from the window
• The effective window height, H, starts 3 feet up from
the floor or at the windowsill, whichever is higher,
and ends at the top of the window.
• Ensure that the view of the Daylight Sensor is not
obstructed
• Do not position the Daylight Sensor in the well of a
skylight or above indirect lighting fixtures
Mount the Daylight Sensor
• Drill a 3/8 in. (10mm) diameter hole in the ceiling tile
or indirect fixture mounting surface
• Thread the wires up through the hole
• Install the Daylight Sensor into the hole
• Secure the Daylight Sensor with the mounting
hardware provided (hand tighten only).
Note - If the stem of the Daylight Sensor must be
shortened due to its location (for instance, in a
pendant fixture) this should be done prior to wiring.
