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.
