General
Shadow tracking control
With shadow tracking control, sun protection is not lowered completely but only so far that the sun can still shine into the room for a certain
distance (e.g. 50 cm), which can be set by adjustable parameters.
Benefits: This enables room occupants to look outside through the lower part of the window, and plants arranged on the windowsill can still be
exposed to direct sunlight, while the room occupants are protected. This creates an optimum room climate, ensures glare-free workplaces and
lowers energy demand and costs for room lighting.
