With color temperature (Tunable White), the light temperature can be controlled. A 4 bit dimming
command is available for the control. This allows a dycle through the color 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. A stop telegram is sent with the release.
