Value for Day/Night
determines whether the detector is in Day or Night mode. The parameters set
for Day/Night then apply accordingly.
Sensitivity
The sensitivity of the sensors is set here. 1 means very low, the higher the value, the more sensitive
the sensors become. This setting has an influence on the detection range. If the value is set low,
movement is only detected relatively close to the detector. If the value is set to e.g. 8, a movement is
already detected at a greater distance from the detector.
Note
: From database V4.4 onwards and from device HW R2.5 onwards, it is also possible to set the
sensitivity to level 0 (lowest level).
Brightness
This allows a specific operating range to be specified for the Presence Detector. The parameters
"
Switch-
on threshold “Day/Night”
" defines the brightness threshold below which the detector
detects presence. Above this threshold, no more movement is detected, but the detector does not
switch off the light as soon as the brightness is exceeded; instead, the follow-up time runs normally.
The set threshold value can be changed via object "98 - Set switch-on threshold for light channels".
The value always applies to the current operation. If the detector is in Day mode, the threshold for
"Day" is changed. If the detector is in Night mode, the threshold for "Night" is changed.
The "
Switch off if exceedance
" parameter causes the light channel to switch off immediately when
the set value is reached. The value should not be set too low, however, as this could result in the
light channel switching on/off continuously.
Example: If the detector switches ON and the brightness in the room with the light switched on is
brighter than the "Switch off if exceeded" value, the channel switches off again immediately.
Fallback forced guidance/lock
: If the detector is in a certain state via forced guidance or locking, it
can be defined whether it should fall back into automatic mode
after a fixed time
.
With the setting "
after presence and follow-up time
", the presence in the room continues to be
detected during forced guidance/lock. If there is now no one in the room and the follow-up time of
the channel has elapsed, the set "Manual mode follow-up time..." starts from this point, after which
the detector switches back to automatic mode.
Fallback for external push-button long (manual => auto)
: If the detector is switched to manual mode
via "External push-button long", a fallback to automatic mode "with fixed time" or "after presence
and follow-up time" can also be achieved here. The procedure corresponds to the description in the
previous point "Fallback forced guidance/lock".
