Functions
ACTIVATION WITH MOVEMENT AND TWILIGHT SWITCH
It sends a timed activation message to the KNX/EIB bus, for instance to turn a light on,
when movement is detected in a specific area by IR sensors and, at the same time, when
the environmental light is lower than the set value. Movement detection and the sending
of the activation message is indicated by a brief flashing of the front green LED.
The "Transmission period", which can be customised, is the observation period activated
each time an activation message is sent: if the IR sensor detects movement during this
period, when the time expires a new activation message will be sent, regardless of the
dimming value detected.
The device manages a safety intermission which excludes the IR sensor for 5 seconds
when the commanded actuator switches OFF (it requires the commanded actuator to
send its status information).
This intends to prevent undesired activation, for instance caused by the switching off of
an electrical load with high heat emission.
It is also possible to only activate movement detection when the actuator to be
commanded is ON (conditioned detection). This function mode allows you, for instance,
to switch on lights in the traditional manner (using a button) and automatically switch
them off when movement is no longer detected.
