A Weekly Schedule consists of 10 events. They can be added, deleted, activated and deactivated. For every event its time, mode and week day is
indicated.
The system changes modes according to the Weekly Schedule only when the indicated time comes, therefore a user can always change the existing
mode manually. This schedule notifies of the upcoming mode change by indicating the time remaining till the next event.
The schedule is edited in user environment USER › MENU › SCHEDULE.
This schedule is used when the unit has to operate in uniform mode during holidays. The user interface shows when the schedule period is active as
nobody can change the mode activated by this function (except for protection). In order to control the system in a normal manner, the Holiday Schedule
period must be deactivated, i. e. zero values must be indicated or dates must be changed. Up to five holiday periods can be set.
The schedule is edited in the user environment USER › MENU › HOLIDAY.
The winter/summer function is set during the cold periods, because some parts of the system have to be protected against cold outdoor air. During
