With colour temperature (Tunable White), the light temperature can be controlled. A 4-bit dimming
command is available for the control. This allows a cycle through the colour temperature.
It is a start-stop dimming that means as soon as the dimming function becomes active the control
loop runs through the entire range. The dimming process ends either when the lower or upper end is
reached or when the push button is released again. When released, a "stop" telegram is sent.
