Weekly timer

It is possible to make 28 different settings for one week in total which means up to four settings per
day on 7 days. In this mode, the memory locations have to be made in correct order so that further
free memory shows up. Initially you will see four selectable settings (W1-W4). W5 only shows up if all
four previous ones are used. The approach to enter settings is similar to the daily timer and only differs
by an additional option of the weekday.
