Abstract
The present invention relates to occupancy controllers based on variation in ambient light. Every time a body passes between the source of light and the light sensor, it determines a variation in luminosity which is used to adjust the amount of energy necessary to heat/cool the room itself. The time sequence of the variations and their duration allow the adjustment of the comfort temperature in a way which is natural and very similar to the human habits. During night time there will be a reduced and energy-conserving comfort temperature; during daytime such value will depend on the duration and intensity of the activity undertaken in the room.
