9.2
Command not confirmed
If a receiver (at least one in cases where multiple devic-
es have been taught-in) does not confirm a command,
the device LED lights up red at the end of the trans-
mission process. This behaviour may be caused by the
following:
•
The receiver cannot be accessed.
•
The receiver is unable to execute the command
(load failure, mechanical blockade, etc.).
•
The receiver is defective.
9.3 Duty cycle exceeded
The duty cycle is a legally regulated limit of the trans-
mission time of devices in the 868 MHz range. The aim
of this regulation is to safeguard the operation of all de-
vices 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). Devices 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. However, repeated and radio-intensive teach-
