Teaching-In; Resetting To The Initial State - HomeMatic HM-CC-SCD Bedienungsanleitung

Teaching-in

Please read this entire section before starting the
teach-in procedure.
In order to enable communication between radio components, the
devices have to be taught-in to one another. To execute the teach-
in procedure, both of the devices to be linked must be in teach-in
mode.
To teach-in, proceed as follows:
• Press and release the channel button (within 4 seconds). The
device LED will flash orange for a few seconds. The teach-in
procedure can be aborted by pressing the
teach-in button again briefly (the device LED will then turn red).
• The device to be taught-in then also needs to be switched to
teach-in mode. If both devices are in teach-in mode at the same
time, each will be taught-in to the other.
• Once the teach-in procedure has been completed successfully for
the radio-controlled sensor for carbon dioxide, the device LED will
flash green. How long the LED flashes for depends upon the con-
figuration progress. If the teach-in attempt has failed, the device
LED will flash red.
• If no teaching-in is carried out, teach-in mode will be exited auto-
matically after 20 seconds.
If the radio-controlled sensor for carbon dioxide has
already been taught-in to a central control unit and is thus
blocked for direct teach-in, it can still be put into teach-in
mode as described above, but the device LED will light up
red for two seconds when a button is pressed. Direct
teach-in is not possible. To teach-in the radio-controlled
sensor for
carbon dioxide to another central control unit/HomeMatic
component, reset it to the initial state. The WebUI must be
used for teaching-in to a central control unit.

Resetting to the initial state

The device can be reset to the initial state. Doing this deletes all
information relating to taught-in components.
To reset, proceed as follows:
• Press and hold down the teach-in button (for more than 4 sec-
onds). The device LED starts to slowly flash red. If you wish to
abort the reset at this point, wait 15 seconds. The slow red flash-
ing will stop.
• To reset the device, press and hold down the teach-in button
again (for more than 4 seconds). The LED will now start to flash
red faster. Release the teach-in button to complete the reset pro-
cedure; the LED lights up continuously for around three seconds
to confirm that the reset has been successful.
Possible error messages: The following 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 5 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 sup-
plied with the product. To reset the sensor, you will have to
use the configuration software for resetting the central con-
trol unit. The procedure to follow is described in the manual
for the central control unit software.
