For automatic adapting of the setting values, the actual achieved values after each
completed optimum start control is used as the new basis for calculation. The set
value are adapted if the calculated values and the set values are too great; this
achieves better results for the next optimization.
The optimized setting value is also displayed. The adapted value can be reset to
another start value by switching optimum start control to "On: Values fix" and then
back to "On: Values adapted".
