I'v never worked with Crestron in an instalation, but it seems to
control much more than that (basic on/off).

On the web site of Creston, they say:

"Controls and visualises of 1 Bit, 4 Bit, 1 Byte and 2 Byte values of
EIB-bus modules."


1 bit = on/off
4 Bit - open close shutters
1 Byte - scenarios, brightness, analog
2 Byte = temperature control

In a normal knx interface, you don't have to worry too much with those
infos (1 bit, etc), because the software will present you with a
description of what they mean, and will only let you interface the
correct values.
