2.4.4 Constant light control
The parameter page is visible if constant light control is set at the <Control type> parameter. See page 16 chapter 2.4.1

Application
Behaviour at
start of control
Value telegram
Control is started with a value telegram. The actuator dims up at the set <Dimming
time of 0 % to 100 %>. The detector measures the rising brightness and stops the
dimming process once the brightness level has been reached. Control starts at this
point.
ON telegram Control is started with an ON telegram. The actuator switches on and jumps or dims
up to the configured value. The switching behaviour is significantly determined by
the setting on the actuator.
Example: If a switch-on value of 70% is configured on the actuator, control starts
with this switch-on value, regardless of whether this value is above or below the set
point value.
Behaviour of the control
This parameter is used to change the increment of the sent dimming value.
Standard
Behaviour is set to its optimum level. The change happens gradually and is almost
imperceptible.
Average
Fast
The change happens more quickly.
The change happens more quickly.
Standby light
Inactive
The standby function for A,B channels light is not available.
Active The standby function for A,B channels light is available and the parameters are
faded in.
Standby time light
30 s – 60 mins Standby time can only be set with constant light control. This causes both lighting
groups to dim to the set standby dimming value instead of switching off on comple-
tion of the switch-off delay time. The standby time can be set for between
30 seconds and 60 minutes.
on The lighting stays permanently on standby with standby
on
. The lighting switches
off after 10 minutes if the brightness level in the rooms exceeds the set brightness
level. The lighting returns to the standby value independently without presence if
the room brightness falls below the set brightness level. This guarantees a minimum
level of lighting in darkness.
Standby dimming value
5 % – 10 %
10 %
The available dimming values for standby range from 5 % to 10 %.
The preset value is 10%.
