11.6.10 Extended parameters — Operating mode
Options:
Heating/air-conditioning
Ventilation
– Heating/air-conditioning: The switch-on delay time starts with a movement. If movement is
no longer detected during the switch-on delay time, the switch-on delay time is reset. If
movement continues and the switch-on delay time has expired, the output is activated with
the programmed switch-on value. As soon as movement is no longer detected, the switch-
off delay starts. The switch-off delay is triggered by each movement within the detection
range. After the switch-off delay has expired the output is activated with the programmed
switch-off value.
– Ventilation: A movement in the detection range starts the switch-on delay time. After the
switch-on delay time has expired the output is activated with the programmed switch-on
value. As soon as movement is no longer detected, the switch-off delay starts. The switch-
off delay is triggered by each movement within the detection range. After the switch-off
delay has expired the output is activated with the programmed switch-off value.
11.6.11 Extended parameters — Switch-on sensitivity
Options:
High
Medium
Minimal
– High: During the switch-on delay time the presence detector checks whether there is still
movement in the room. With setting "High," this test interval is very high.
– Medium: During the switch-on delay time the presence detector checks whether there is still
movement in the room. With setting "Medium," this test interval is high.
– Minimal: During the switch-on delay time the presence detector checks whether there is still
movement in the room. With setting "Minimal," this test interval is not high.
11.6.12 Extended parameters — Object for switch-on delay time
Options:
No
Yes
– No: There is only the option of changing the switch-on delay time via the “switch-on delay”
time parameter.
– Yes: There is a separate 2-byte “switch-on delay time” (input) object for changing the delay
time of the presence detector. The time entered is in seconds. A switch-off delay of 4
minutes, for example, has a value of 240 seconds.
Note
The values which can be sent are between 10 and 65535 seconds. If a value
that is too small or too large is sent, the value is automatically adjusted to the
limit value:
– Value < 10 -> value = 10
– Value > 65535 -> value = 65535
