A typical application of the stop function is to force
the lights to turn off in a room during a projection
or to force the lights to turn on in an environment
where the detected brightness is greater than the
set threshold.
For as long as the device detects the presence of
people, the adjustment will be disabled considering
the manual selection of the user as a priority. The
sensor will return to directly control the lights only
at the end of the follow-up time.
It is possible to set the parameter "Automatic restart
time"; it defines the duration of the sensor
adjustment disabling time, when it expires the
sensor resumes its automatic behavior.
These communication objects are also available:
< Channel x> Activated/Stopped
The first CO force to exit from the stop state upon
receipt of a "0" or "1" telegram; the second sends the
active / stop status on the bus with telegram "0" or
"1".
Stop state after
download
Defines whether the device is in Stop or not after
download
Stop state after power on
activated / stopped / state
before OFF
Define the status of the stop function on power-up
Defines which telegram determines the exit of the sensor
channel from the manual forcing status (stop)
Defines which telegram is sent on the bus to indicate that
the sensor channel is active again (not in stop), the
opposite telegram will signal the manual forcing status
(stop)
Automatic restart time
(0=unlimited) [min]
If different from zero, this parameter defines after how
long the sensor channel exits the manual forcing (stop)
and returns to automatic mode.
Utilization function
Function available on product code PD00E03KNX
SPACE_sensor
The UTILIZATION function is associated with each
channel which includes the presence detection
function, the function can be enabled on the
channel pages. Using the UTILIZATION function it is
possible to calculate the percentage of time in
which the presence of people in the area monitored
by the sensor is detected.
An ETS parameter defines the evaluation time
which can vary from 1 minute to 4 hours; it is
recommended to keep monitoring time values from
5 to 60 minutes in order to make data collection as
granular as possible and leave it to the supervisor to
process it.
The usage data, expressed as a percentage, is sent
at the end of each surveillance period using a 1 byte
object. Another 1-bit object is used to force the
sending of the percentage data as well as to
synchronize the different sensors of the building so
that the transmitted data can be compared. The
ability to manage the sending of data on request is
also useful for collecting data with variable
frequencies throughout the day.
Occupancy FUNCTION
Function available on product code PD00E03KNX
SPACE_sensor
The occupation function detects data to be used to
process information related to the intensity of the
activity of people within the areas monitored by the
sensor, this activity is proportional to the number of
people present and allows you to generate a "heat
map" of the areas of the buildings . The heat map,
usually correlated to the hours of the day, identifies
which areas of the buildings are used during the
various hours of the day and with what intensity by
providing precise information to the building
manager. The analysis of the occupancy data of a
building in fact highlights any planning errors of
energy resources as well as possible optimizations
of the use of individual and common spaces.
