• Receiver cannot be reached.
• Receiver is unable to execute the command (load failure, me-
chanical blockade, etc.).
• Receiver is faulty.
7.4 Duty cycle
The duty cycle is a legally regulated limit of the transmission time of de-
vices in the 868 MHz range. The aim of this regulation is to safeguard 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). Devices must
cease transmission when they reach the 1% limit until this time restriction
comes to an end. Homematic IP 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 radio-intensive pairing processes mean that it may
be reached in isolated instances during start-up or initial installation of a
system. If the duty cycle limit is exceeded, this is indicated by the LED (G)
emitting a long red flash, and the device may temporarily not function.
The device will start working correctly again after a short period (max. 1
hour).
