The window contact is connected directly to a digital input on the room controller (see
page 126). Alternatively an EIB/KNX window contact (connected to the bus) may be
used. The application evaluates both items of information (logic OR operation).
Since EIB/KNX window contacts are available from a variety of manufacturers, the
name of the S-mode output communication object varies accordingly.
