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 fre-
quency 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 wireless-intensive teach-in processes mean that it may be
reached in isolated instances during start-up or initial installation of a sys-
tem. If the duty cycle is exceeded, this is indicated by one long and one
short red flash of the device LED, and may manifest itself in the device
temporarily working incorrectly. The device starts working correctly again
after a short period (max. 1 hour).
