Planning and application
If the increment is too large, the light control reaches the setpoint faster. The setpoint brightness is
exceeded. The DLR/A starts to oscillate around the setpoint brightness.
If the increment is too small, it will take too long until the setpoint brightness is reached. This is critical,
particularly in cases where blinds are closing to darken the room quickly.
