Set time/date, summertime/wintertime and

Programming
A program consists of an ON time, OFF time and associated
ON and OFF days.
Programs with predefined on/off days (Mon to Sun, Mon to Fri
and Sat and Sun): for these programs, you only need to set
the switching times.
With the "INDIVIDUAL" option, you can allocate switching times to
specific days of your choice.
The programs of a channel are linked to one another
by logical OR.
