Product and functional description
The UP 258D11 is a presence/motion detector with inte
grated 2 point light control. The UP 258D11 device com
municates via KNX/EIB with actuators or other KNX de
vices. It is designed for mounting on the ceiling. Owing
to its tilting sensor head, the UP 258D11 can be aligned
with the required capture area. The main application for
the device is automatic lighting control in an office
workplace.
The UP 258D11 senses the presence of a person or that
there is no longer anyone in its detection area. The de
tector signal can be analyzed via two separate communi
cation channels, termed motion detector and presence
detector.
Additionally, the UP 258D11 provides an output for con
trol of HVAC applications. For example, this function can
switch systems that are used for heating, ventilating and
air conditioning control (HVAC) of the room from “En
ergy saving mode” in an unused room to “Comfort mode”
in an occupied room and back to “Energy saving mode”
when the room is again unoccupied.
For each detector function block (presence, motion,
HVAC) 4 communication objects are available, in total 12
different communication objects. Depending on configu
ration, one or two KNX telegrams are sent onto the bus
when motion is first detected and when, after the last
motion was detected, an overshoot time has expired.
The values of the communication objects are configured
for each functional block (motion detector, presence
detector, HVAC detector) via corresponding parameters.
Each time a presence is detected, the overshoot time is
started. Its duration is separately configurable for each
functional block. The end of presence is determined by
the end of the overshoot time.
The duration of the dead time is also configurable per
functional block. It is used to protect the actuators that
are connected to the detector. If a presence is detected
during the dead time, neither telegrams are sent nor the
overshoot time is started.
In the following the telegrams, which are sent at the
beginning of a presence, are called
A
and
B
, the tele
grams, which are sent at the end of a presence, are
called
C
and
D
.
Operating Sequence
After the device has detected a presence, telegram
A
is
sent immediately. If it has been configured to send also a
telegram
B
, then telegram
B
is sent after the configured
time (optionally also cyclically).
If there are no motions any more, at the end of the over
shoot time telegram
C
and (if configured) telegram
D
are
sent. Telegram
D
can also be sent cyclically.
If there are motions while the overshoot time is running,
the overshoot time is restarted.

Use as single device or as main detector (master),
respectively secondary detector (slave)
The detector can be operated as an independent device,
as the main or secondary detector.
According to the requirement, additional presence detec
tors can be connected with the “main detector” via
KNX/EIB as “secondary detectors” to extend the presence
detection zone. “Secondary detectors” supply motion
information only to the main detector.
Brightness measuring – adjustable via KNX/EIB
The UP 258D11 contains an independent light sensor.
The signal measured there is available both at the
KNX/EIB and internally.
Because the light sensor measures directly, it must be
possible to calibrate it for indirect measurement, so that
it can be adapted to the different installation sites. Rapid
