11.16.11 Px: Saving setpoint brightness
Number
12 | 30
The desired brightness value is set with a control element via communication objects automatic
/ manual off, relative dimming (dimmer) and / or value (dimmer). If, for example, the luxmeter
shows the value 500 lx, this brightness value with the sending of a 1 will be stored on this
communication object as new setpoint of the control. Note: When setting the desired brightness,
e.g. 500 lx, the lamp's light-up time is to be taken into account.
11.16.12 Px: Actual brightness
Number
13 | 31
The current (filtered and corrected with daylight and constant light correction) brightness value
is made available via the "Actual brightness" communication object.
11.16.13 Px: Move/adjust blind
Number
14 | 32
The object is connected with the move command of the control element. When a value 1
(moving up) or 0 (moving down) is received, the parameters set under "Control parameters for
blind movement" become active. The switch mode is deactivated after a programmed time and
the normal control algorithm is reactivated.
11.16.14 Px: Move blind into position
Number
15 | 33
The object is connected with a 1-byte position command of the control element / actuator. When
a value is received, the parameters set under "Control parameters for blind movement" become
active. The switch mode is deactivated after a programmed time and the normal control
algorithm is reactivated.
