8.2 Operational status display
The device LED
(B)
lights up permanently as soon as the switch actua-
tor is switched on.
After configuring the switch actuator with the Central Control Unit or
a programming tool, the device LED indicates other device states be-
sides those described (e.g. switch on and off delay or duration).
8.3 Duty cycle
The duty cycle is a legally regulated limit of the transmission time of
devices in the 868 MHz range. The aim of this regulation is to safe-
guard the operation of all devices working in the 868 MHz range.
In the 868 MHz frequency range we use, the maximum transmission
time of any device is 1% of an hour (i.e. 36 seconds in an hour). De-
vices must cease transmission when they reach the 1% limit until this
time restriction comes to an end. HomeMatic devices are designed and
produced with 100% conformity to this regulation.
During normal operation, the duty cycle is not usually reached. How-
ever, repeated and wireless-intensive teach-in processes mean that it
may be reached in isolated instances during start-up or initial installa-
