Holiday

After activation, the holiday program is executed between 0:00h on the start date and 24:00h on the end date

(Constant ON/OFF). After the holiday program has run once, it must be reactivated.

Summertime: ± 1 hour

Europe: Factory set.

SPECIAL: The switchover to/from

summertime can be freely programmed by

entering a start date and end date

and is then executed each year on

the same day of the week, e.g.

Sunday.

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.

CHRONO = All switch commands are executed in chronological order in a week

INPUT = Programs are executed in the order in which they are entered
