CWT
This object is used to report that device is still alive and connected to the KNX line by sending cyclic 1 bit
telegrams. If a telegram is not received, device may be defective or KNX cable would be intercepted.
-
Object will be activated if “Device alive operation active” parameter in the General tab is selected as
“yes”.
-
Telegram type (ON or OFF) can be selected via “In operation bit” parameter in General parameters
tab. Cyclic period of transmitted telegrams can be selected via “In operation send interval” parameter in
General parameters tab.

“Presence slave 1, 2, 3, 4” objects will be visible according to “Number of lighting group” parameter in
“General” window.
If required, 4 additional motion detectors can be connected to the master as slaves in order to extend the
detection zone. Presence information of connected slave sensors are received via these communication
objects by master sensor. Slave sensors send the value “1” when movement is present, otherwise send
value “0”. These values are processed in OR gate by master sensor. If the output value is “1”, master sensor
accepts that there is movement in area. In other words master sensor ascertains “overall presence”.
Note: Only one slave sensor should be in relation with one communication object. Lights can stay “ON”, if
slave sensors are disconnected from KNX line before the master sensor is switched off.

CRT
Presence information of detector is sent via this object. Cyclic period of object can be selected. This object
has a short reaction time (15s, 30s) so that detection tests can be done easily.
-
Object value is “1” if movement is present.
-
Object value is “0” if there is no movement.

CRW
Presence output object can be disabled/enabled via this object.
-
A write should be made to the object with value “1” to disable.
-
A write should be made to the object with value “0” to enable.

Presence
Switch “ON” delay time
DPT 5.005
8 bit
CRW
This object is only visible if the "Switch-on delay and stay-on time change by bus" parameter is set to "yes" in
the "Presence" parameter window.
This object is used to receive presence detection switch-on time (in seconds) by the bus. After a detection,
sensor waits until “Switch ON delay time” is expired and sends the presence information to “Presence
output” with a secondary detection.
