5.2.14 Keyword Function for Keypad
The System can be protected by a key-word against unauthorized changes via the keypad to
the settings.
Warning: In the case of Systems 6844, if the keyword is lost this can
only be reset at the
hopf
factory.
In 6844RC Systems, the keyword for the keyboard can be reset by trigger-
ing a factory default via the remote interface.
In order to avoid delays during commissioning, the keyword should only be set
after commissioning has been completed. The keyword should be kept in a
safe place and protected against unauthorized access.
If a keyword has been set then this is requested after a selection has been made from the
main menu.
If the keyword is entered correctly then the display changes to the selected menu. The key-
word protection is then deactivated until the selected menu has been exited. The keyword
protection is automatically reactivated after exiting the menu by pressing
BR
or after 255
seconds without pressing a key.
No keyword is set up in the factory.
