recommended to check the detection also in
relation to the sensitivity value set. The higher the
sensitivity set, the greater the sensor's ability to
detect "small" movements. High sensitivity values
can lead to false detections caused by "thermal
noise": carefully read the warnings in paragraph
Errore. L'origine riferimento non è stata trovata.
to
reduce the possibility of false detections.
6.
Presence Module
The presence module provides a parameter for
setting the sensitivity of the PIR sensor, this
parameter will also affect detection for channels 1
to 5 that use presence; the remaining parameters
are connected only to this module.
KNX PARAMETER
SETTINGS
Sensor sensitivity
Very high sensitivity
high sensitivity
normal sensitivity
low sensitivity
very low sensitivity
Use low sensitivity values when the sensor is placed in
"thermally noisy" environments, for example in the
presence of sources of hot or cold air emissions (see
installation suggestions); high sensitivity values can be
used when the sensor must detect "small" movements
such as those of a person working at a desk.
Sensor sensitivity day
If the day-night switching
object is enabled (general
parameter), it will be possible
to diversify the sensitivity at
different times of the day
Sensor sensitivity night
Presence sensor
send absence only
send presence only
send both absence/presence
For the basic module it defines in which cases to send the
1 bit telegram.
Presence telegram
OFF is presence
ON is presence
Defines the value of the 1-bit telegram per presence; the
opposite value will be used for absence.
Follow up time
Hours
Minutes
Seconds
0..24
0..59
0..59
Sets the follow up time
Output cyclic send time
No cyclic sending
h
Set the period of cyclical sending.
Follow up time
The presence telegram is sent in the presence
module when the sensor detects presence [A]; the
device waits for the follow up time to elapse before
sending the absence telegram [C]; if a new
movement [B] is detected during the monitoring
time, the follow up time restarts. The absence
telegram is sent only when the follow up time ends
without any movement being detected [D]
7.
Illuminance module
In this module the parameters relating to the
brightness sensor are configured (not present on the
model PD00E00KNX - BASIC).
Adjustment of the illuminance sensor
It is very important to carry out a correct and
precise calibration of the illuminance sensor; in fact,
the sensor must measure the illuminance on the
placed in a different position
(on the ceiling). The sensor receives reflected light
and the reflection depends on the reflective
capacity of the floor or furniture and the distance
from the windows.
