Factor for daylight compensation in % [0...99]
Options: 0...35...99
A larger value compensates more for natural light. This means that
artificial light has a higher weighting which also means that more
artificial light is added and that the light is switched off later as a
result. The room will remain brighter than the setpoint brightness.
A smaller value compensates less for natural light. This means that
artificial light has a lower weighting and that less artificial light is
added. The setpoint value tends to be slightly undershot and the
artificial light is switched off earlier.
In practical usage it has been demonstrated that – depending on
the ambient conditions – a factor of between 30 and 50 generally
provides the best results in most cases.
Restore factor for daylight compensation during download
Options: no
yes
This parameter defines if the factor for daylight compensation is
overwritten with the value from the ETS.
•
yes: With a download the value stored in the Light Controller for
daylight compensation is overwritten with the value set in the
ETS.
•
no: The factor is not overwritten during download. This is useful
for example, if you want to avoid that the values which have been
determined over the course of many attempts in then Light
Controller are not overwritten by mistake and that a renewed
calibration is required.
