13.4 Auto / Semi-auto mode (absence detection function)
This function is enabled with ETS
®
setting and it is used to activate / deactivate Auto mode or Semi-
auto mode of Light control output C1.
The behaviour is as follows:
Under auto mode, the load will turn on automatically when a movement is detected and the
ambient light level is below the Lux setting value. When movement is no longer detected and
the delay time has expired, the load will turn off automatically.
Under semi-auto mode, the load can only be manually switched on by operating via a
connected external pushbutton. When the load is switched on, it will keep be on if the
movements are detected constantly. The load will turn off only when movement is no longer
detected and the delay time has expired.
Please refer to section 14.3 for further information.
13.5 Test mode
Parameters can be set via ETS
®
. Test mode switches to th
e RUN status after “storing”, or 10 min
after activating the test mode. Load and red LED are not controlled by Lux setting under the Test
mode. Once the detector is triggered, both load and red LED turn on for 2s, then turn off, and the
next triggering should be 2 sec interval.
IMPORTANT
:
The settings of functions described in paragraphs 13.6, 13.7, 13.8, 13.9 and 13.10 are
intended for lighting control, therefore do not apply to HVAC control.
13.6 Manual ON / OFF and DIM switching function
This function is enabled with ETS
®
setting and operated either by the slide switch loacted under the
frontal cover, or through a connected KNX interface module on KNX bus system.
Please refer to section “Parameter setting“ - “Communication objects description“ for further
information.
13.7 Master / Slave selection
This function can only be set via ETS
®
software and it allows to set the device as a master or slave
device:
when detector is enabled as master device, all the functions are available and it also can
receive the triggering signal from one or more slave detectors;
if it is enabled as slave detector, then it works exclusively to extend the field of detection and
all its function are managed by a master detector.
Please refer to section “Parameter setting“ - “Communication objects description“ for further
information.
13.8 Ambient light appraisal
In case of changeable ambient light level, the detector can postpone delay time of turning on and off
loads, in order to avoid its unnecessary on or off switching.
This behaviour works in two ways:
The ambient light level changes from bright to dark: to avoid unnecessary switching on / off
of the load due to temporary variations in the ambient light value caused by events (e.g.
i
