The CD250 PIR Dimming Multiway Vacancy Sensor provides preset dimming control and automatic lighting shutoff for applications in the home including those with multiple switch locations. It is engineered to comply with Californias Title 24 2008 residential energy code. The CD250 operates as a manual on sensor. Users must press the pushbutton to turn on lighting. Once lighting is on, the dimming level may be adjusted by pressing and holding the pushbutton. The CD250 employs PIR technology to sense the difference between the infrared energy from a person in motion and the background space. It keeps lighting on as long as motion is detected and provides automatic shutoff, following a user selected time delay, when motion is no longer detected. Users may turn the lighting off manually. The next time the CD250 is turned on, the lighting will come on to the last light level.
