Avoid aiming the control at:
• Objects that change temperature rapidly, such as
heating vents and air conditioners. These heat
sources could cause false triggering.
• Areas where pets or traffic may trigger the control.
• Nearby large, light-colored objects reflecting light
may trigger the shut-off feature. Do not point other
lights at the sensor.
