Length of Detection: sets the minimum time that should elapse without any
motion before the channel switches to the "No Detection" state. Further
motion events will interrupt this countdown. The range is 1 to 255 seconds, 1
to 255 minutes and 1 to 18 hours.
Example: Detection Length.
One MAXinBOX 66 and one motion detector are being used to turn on/off a light
source (which is connected to a KNX light dimmer) depending on whether motion is
being detected or not in the room.
If the detection length is set to 5 seconds, as soon as the detector finds moving
subjects in the room, MAXinBOX 66 will send the "Detection" value to the dimmer, so
that the light source turns on. After five seconds without detecting motion again (even if
the subject is still in the room), MAXinBOX 66 will send the "No Detection" value to the
dimmer, so the light source turns off.
On the other hand, if a 60-second detection length is parameterised, the light will
remain on at least for 60 seconds, as 60 seconds of no detection are necessary before
sending the "No Detection" value. The greater the detection length is, the more
evidence that the subject is not in the room is required before turning the lights off.
Blind Time: sets the time margin during which the channel will remain
inactive whenever it enters the "No Detection" value. This ensures that the
"No Detection" state is maintained at least during that time interval, even if
there is motion in the room, which will be ignored by the channel. The range
is 1 to 255 seconds, 1 to 255 minutes and 1 to 18 hours.
Reset Luminosity after No Detection: enabling this parameter will set the
"[Ix] Luminosity" object to 0% whenever the channel leaves the "Detection"
state and enters the "No Detection" state. There is also the option to
configure a delay.
 Reset Delay: imposes a delay before resetting the value of the luminosity
object. The range is 0 to 60 seconds.
This parameter is useful when combined with the Luminosity-Constrained
Detection function. Therefore it is advisable to read the examples about such
function in later sections of this manual.
