Settings Options and Partitions MenusPage 57 If you create an event to unset a partition, and another event to set the samepartition again, you must program the setting event to occur at least 10 minutesafter the unsetting event. The control unit adjusts its clock in Spring and Autumn to allow for Summer DaylightSaving Time. At the Autumn change-over, avoid configuring any unset events totake place during the changeover time on the Sunday morning. For UK systems,this time is 01:00 to 02:00. For EU control units, this time is 02:00 to 03:00. If thecontrol unit unsets any part of the system at these times, it will NOT set the systemagain when the clock changes back to Winter Time.Manually setting and unsetting partitions does not alter the times programmed in calendarsets. If a user sets a partition that is due to be set by a calendar event, the partitionremains set when the calendar event time is past. Likewise, if a user unsets a partitionbefore a calendar event is due to unset the partition, the partition remains unset.Add EventUse this option to create an event. When you select the option, the control unit will guideyou through the following series of options:Event NameEnter up to 12 characters or press  to leave the default name.Event TimeSpecify the time you want the event to occur, then  to display the next prompt.The time “00:00” is midnight, at the beginning of a new day.Note that if you specify a start time that is less than 10 minutes from the current timeshown by the control unit clock (that is, less than the period set by Warning Time),the event will not take action until the following day.Event DaysChoose the days you want the event to occur.Press  or  to scroll through each day of the week. Press  or  to specify Yesor No.Event ActionsIn a partitioned system, press  or  to scroll through each partition, and  or  toselect No (no action), Full (full set), Part (part set) or Unset.In a part-setting system, select one of: Full Set, Part Set B (or C or D) or Unset.Event ExceptionsChoose the exceptions (set up using Add Exception) that you want to apply to theevent.Press  or  to scroll through the list of programmed exceptions. Press  or  tospecify Yes (the exception applies to the event) or No.Warning TimeSpecify the period (in minutes) you want the control unit to sound the warning tonebefore the start of a setting event. Enter between 1 and 30 minutes. The default is10. There is no specific warning indication for an unset event.The warning tone sounds at the internal sounders allocated to the partition(s)specified in the event.At the beginning of the warning time, the control unit activates any outputs of typeAutoset Warning (see page 44).
