The Hubbell Dimming Wall Switch Sensor combines passive infrared (PIR) technology with the additional energy savings of 0 to 10 VAC dimming. The light level can be either predetermined or the sensor can be configured to remember the last dimming setting upon occupancy. With manual override ON/OFF and dimming control, the light level can be easily adjusted to a desired set point. The sensor features Hubbell patented Adaptive Technology, which continuously analyzes its environment and auto adjusts the sensitivity and timer based on environmental history, eliminating the need for manual adjustment. This helps provide true maintenance free "Install and Forget" operation. This series also feature selectable Automatic ON/OFF or Manual ON/Automatic OFF, or vacancy only operation modes and a built-in photocell for automatic daylight harvesting.
