Follow-up time of the inactive control in s [0...65,535]
Options: 0...60...65,535
If constant lighting control is deactivated or interrupted by the user, e.g. by
manual dimming, the current brightness value is stored for the duration of
the follow up time. The follow up time commences with the deactivation of
the light control. If the lighting is switched back on within the follow-up time,
the light control is not reassumed and the lights are controlled with the
stored brightness value. If the lighting is switched back on after the follow-up
time, light control is reactivated and the Light Controller assumes control.
If constant lighting control is switched off the follow-up time is not activated.
Lighting control is interrupted.
This function should re-establish the same level of lighting for persons
who leave the room and return after a brief period. It is particularly useful
if the lighting is automatically switched by a presence or motion detector.
