Two communication objects appear for this button. Firstly, the function for a short button action, the
"Dimming On/Off" switch object, and secondly the function for a long button action, the dimming object
"Dimming relative". The dimming function is a start-stop dimming function, i.e. as soon as the dimming
function becomes active, a brighter or darker command is assigned to the input until it is released. After
the command is released, a stop telegram is sent which ends the dimming process.
