  • Self-commissioning daylight switching system
    Patent number: 7045968
    Abstract: A method of commissioning a switch to control an electric luminaire in an indoor space responsive to signals from a photosensor. A first plurality of sensor signal values is calculated when the photosensor is disposed at a first location within the space. A second plurality of sensor signal values is calculated when the photosensor is disposed at a second location within the space. A first threshold value is calculated for switching on the luminaire when light in the space is less than a first value. A second threshold value is calculated for switching off the luminaire when light in the space is greater than a second value.
