This application program applies to all instabus wall
switches that are mounted on a bus coupling unit (BTM)
UP 117.
When expanding the number of switch buttons or the
functionality (e.g. from UP 285/_2 to UP 287/_5) the prior
configuration remains and must only be expanded.
In the same simple fashion switching between design
lines (DELTA line / vita / miro or DELTA style) is possible.
Configuration and operation of all instabus wall switches
is identical independent of design and the number of
switch buttons.
