Perform a fast dynamic teach-in by pressing and holding (1second) TEACH
(confirmation teach-in start) and then pressing and holding (1second) TEACH
(confirmation teach-in stop).
The switching point (SP) is determined while the process is running. Between
starting and stopping teach-in, the maximum and minimum received light values
are determined as teach-in points (TPmax, TPmin). The switching point (SP) is
updated according to the determined teach-in points (TPmin, TPmax) and the
display returns to run mode.
