of the left or right side of the button will send out an ON or an OFF telegram. Alternatively,

Alternatively, when selecting "Alternating brighter/darker", you can switch between
dimming brighter and darker with each long operation.

darker telegram will be sent out for a renewed operation. After it is operated again, a dim
brighter telegram is sent out.
