Vacancy or occupancy mode is easily selected. As it uses dual technology (DT), this sensor is highly resistant to false ON events. Light Level Sensor Mode: Each unit includes an adjustable light level sensor to hold-off artificial lighting when adequate natural light is present. Walk-Through Mode: To maximize energy savings, the sensor detects when areas are briefly occupied as a result of a person walking through and turns OFF lighting based on a shorter time delay. The single circuit DT Wall Switch Occupancy Sensor requires a direct line of sight to room occupants in PIR mode only.
