The functional difference with regard to the ceiling detector mode lies...
a) in the processing of the movement signal
Contrary to the ceiling detector mode, a presence is detected only after several
successive movement pulses have been received.
b) in the processing of the brightness signal
The presettable brightness range to be monitored for the brightness threshold value
is larger than in the ceiling detector mode.
It is only after twice the value of the preset brightness threshold (switch-off brightness)
has been exceeded that the programmed telegram representing the end of detection
is transmitted after ca. 10 minutes even if someone is still present.
This switch-off brightness can be changed with a correction factor in the programmed
parameters.
c) in the evaluation of combined movement and brightness signals
The light is switched on when a person is present and when, at the same time, the
brightness falls below the preset brightness threshold.
The light is switched off when nobody is present or when the ambient brightness
without artificial lighting is high enough.

Signalling mode (only in the 'Komfort' version)
In this mode with a signalling function, the device detects movement pulses
independent of brightness and counts them with a pulse counter. If – within a fixed
time-span (standard value: 10 seconds) – at least the fixed number of pulses
(standard value: 4) have passed the counting gate, the programmed telegram
representing the beginning of detction will be transmitted.
When no movement pulses are detected anymore, the presence detector transmits
the programmed telegram representing the end of detection after the standard
transmit delay of 10 seconds has elapsed. In the signalling mode, the presence
detector 'Komfort' is always operated as an individual unit.
Further product features:
• Alarm function: When someone tries to remove the device, the detector can be
made to transmit a programmed telegram.
• Teach-in function: The switch-on threshold within the brightness range can be
changed by means of an instabus EIB telegram.
A more detailed description of the functions is given in the instabus documentation
for these products.
