the Comfort level (21 °C) and reduced again when people leave.

(24 °C). When the room is not occupied the temperature will be increased to the Precomfort

People manually switch on the lights via the push buttons. After a certain time after they
have left the room, all lights are automatically turned off. The lighting groups are dimmed
according to the natural light contribution to maintain a constant brightness level in the room
when occupied.

The blinds are controlled automatically. However, manual operation will be possible at any
time. When the sun rises all blinds are raised automatically. When the sun shines on the
facade, the blinds are driven to a certain position to protect people from excessive solar irra-
diance by maintaining comfortable lighting conditions in the room. After sunset, the blinds are
automatically lowered.
