Description
Object 13
Central command
Receive
An ON telegram switches on A,B channels light. The behaviour of the presence detec-
tor is identical as if the user switches on via a push button. The behaviour depends on
the selected control type. See chapter 3 page
An OFF telegram causes: the switching off of A,B channels light in accordance with
the following conditions.
-
no movement with the last 5 seconds:
The light switches off immediately. The ongoing switch-off delay times for A,B
channels light and standby are set to 0. The presence detector then returns to
normal operation.
-
Movement up to receipt of OFF telegram:
The light stays on.
Fully automatic:
-
If further movement is then detected, the light switches on again if there is insuffi
-
cient brightness.
Presence detector is disabled
-
The central command is not carried out.
Object 14
External scene
Receive
Object available if "active.." has been selected at <Disabling light channels with
external scenes>.
Scene numbers sent straight to the actuator can be directed to the presence detector
to maximise the influence on the behaviour of the presence detector.
See page 27 chapter 2.4.15
Object 15
G channel brightness Send lux value
Object available if "active" has been selected on <G channel, send brightness value>.
G channel brightness sends the current brightness measurement as 2-byte telegram
via object 15. The frequency of telegrams depends on the cycle time and the minimum
change in brightness.
The 2-byte telegrams via object 15 provide visualisation of a brightness value, but
should not be used for an external control. The use of the presence detector's internal
constant light control is recommended for that sort of control.
The brightness measurement can be adapted to the conditions in a room with the
room correction factor. See page 19 chapter 2.4.3

Description
Object 16
H channel presence: Switching
Object available if "active.." has been selected at <H channel presence>.
H channel presence sends an ON or OFF telegram or no telegram if there is a presence
(independent of brightness after a delay due to configured switch-on delay). An ON or
OFF telegram or no telegram is sent after expiry of the switch-off delay.
Object 17
J channel presence: Send value
Object available if "active.." has been selected at <J channel presence>.
J channel presence sends an ON telegram or no telegram if there is a presence (indepen-
dent of brightness after a delay due to configured switch-on delay)
Object 18
H,J channel
presence
Disable/enable
Object available if "inactive" is NOT selected in <Disable presence channels>.
The presence channel is disabled via an ON or OFF telegram. At the start of the disabling
process, the presence channel optionally sends one of the following telegrams: ON,OFF,
no telegram. While disabled, the presence channel does not send any telegrams, based
neither on presence/absence nor brightness.
The presence channel is enabled via an ON or OFF telegram in addition to the telegram
when setting disable process. After the enable process is completed, the presence detec-
tor sends its current status.
