Command Not Confirmed; Duty Cycle Exceeded; Restore Factory Settings - HomeMatic HM-RC-8 Bedienungsanleitung

Errors and information indicated by the device LED
the battery has been allowed a brief recovery period.
If you are using weak batteries, the device may perform
a restart automatically when you press a button. The
device LED then briefly flashes red, green and orange,
and follow this with 5 brief red flashes to indicate that
the batteries are weak.
7.3 Command not confirmed
If a receiver (at least one in cases where multiple de-
vices have been taught-in) does not confirm a com-
mand, the device LED lights up red at the end of the
transmission 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.

7.4 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
50
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 system. If the duty cycle is exceeded, this is indi-
cated 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).

Restore factory settings

When the factory settings of the remote control
are restored, all setting will be deleted.
To restore the factory settings of the remote control,
please proceed as follows:
• Press and hold the teach-in button (G) for at least 5
seconds. The device LED starts to flash red slowly.
To cancel the reset process, press the teach-in
button again briefly or wait for 20 seconds. In
both cases, the slow red flashing and the reset
process stop.
