Planning and application
Implementation
Manual daylight calibration
1. Enable manual daylight
calibration.
2. Load the factor for
daylight calibration in
the Light Controller.
3. Checking of controlled
brightness value.

smaller
Note
After a reset or discharge of the Light Controller via the ETS, the stored
values, e.g. lighting characteristic curves, are still available to the Light
Controller. The calibration must be performed again.
The values are overwritten only after a new calibration. The artificial
lighting and the daylight calibrations should be considered separately in
this case.
This is independent of if the calibration has been performed manually or
automatically.
The artificial lighting and daylight calibration must be performed again with
a change of the Light Sensor arrangement.

End
Effect
Parameter for the
assignment of a factor for
daylight calibration is
enabled.
The factor is stored in the
LR/S after download. Light
control is started.
The factor must be
reduced if the constant
brightness to be set is
greater than the required
setpoint.
The factor must be
increased if the brightness
is too small.
Step 2 should be repeated
until the required
brightness is set.
