6.4 Time programs
For the heating circuits and DHW heating, a number of switching programs are
available. They are activated in Automatic mode and control the change of the
temperature levels (and the associated setpoints) via the selected switching times.
The switching times can be set in a combined way, either commonly for several days,
or separately for individual days. The preselection of groups of days like for instance
Mo...Fr and Sa...Su that use the same switching times simplifies setting of the switching
programs.
