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 combined with a logical OR.
