Possible error messages:
(This error can only occur if you have a central control unit to which you
have taught-in the device.)
If the LED does not start to flash when the button has been held down
for five seconds, but lights up continuously instead, the device cannot be
reset.
In this case, coding is activated using a system security key that differs
from the one supplied with the product.
To reset the sensor, you will have to use the configuration software for
resetting the central control unit. The procedure to follow is described in
the manual for the central control unit software (available for download in
the „Downloads" area of the website www.homematic.com).
