* In addition to the previous constant light control channel 1 (Object 22
for light channel 2. Internally, the control range has been extended to ± 150% in order to maintain a reasonable control range at the limits.
That means: Offset at -50%, darkness: FF (=100%) is sent to both objects. Internally, object 1 is at 150% and object 2 at 100%. If the ambient brightness now increases, object 1 remains at 100% (150% - x) and object
2 is regulated downwards (150% - 50% - x). If the regulation now drops below 100%, object 1 will also be visibly smaller on the bus, e.g. 73%, object 2 23%. Object 1 is then regulated down to 0 and object 2 is set to
the minimum value of 50%. The values for transmission difference and cyclical transmission are taken from the once off available parameters.

This parameter enables or disables the constant light controller.
Channel 2 can be enabled for constant light control
Active/inactive Via the output object 23 a configurable value with a fixed offset can be transmitted
The preset setpoint in lux for constant light control can be preset in the ETS. It can also be changed via objects 17 and 18 (constant light - dimming relative and
constant light - dim completely).
This parameter (from 1% to 100%) defines the tolerance window to be exceeded in order to send a new brightness control value.
Switching constant light control ON/OFF can be done using three different sources:
By object 16, presence detection on the light channel or presence detection on the HVAC channel.
Defines the cycle time interval with which the last brightness value is repeated, even if it has not exceeded the tolerance window.
Cyclical transmission can also be disabled.
The switch on value for the lighting can be set from 1% to 100 %.
This parameter defines the initial time delay before constant light control is started.
The offset range for channel 2 can be set from -50%, 0% to +50%.
This parameter allows the constant light controller function to be set to: no reaction, minimum brightness, maximum brightness
This parameter allows the constant light controller function to be set to: no reaction, minimum brightness, maximum brightness
This parameter allows the relative dimming time to be set. This will influence the dimming soft control.
This parameter allows setting the time delay after which a new setpoint will be recognized and stored in the RAM memory.
This parameter allows a new set point to be written to the flash memory.
Here at Yes the changed value is stored in the RAM .
Attention: now corresponds to the new nominal value of the last new dimmed brightness !
Various lux values can be set as light scenes (light moods).These can be enabled through object 21 as well.
The dead zone is an area within which the actual light value can change without generating new control commands. The default value for the dead zone is 2.
The lux value tolerance of the dead zone can be extracted from the table below.
Example:
Dead zone value = 2
Brightness = 500 lux
The resulting tolerance is: +/- 24 lux
This means that the actual value can change from 476 lux to 524 lux without sending new control inputs to the actuator.
) there is a second constant light control channel 2 (Object 23 ). The control signal of channel 1 ± offset value is sent to the dimming actuator
