User Menu OptionsPage 51Note: You cannot program an event to change the system/partition directlyfrom one part set level to another. You must program an event tounset the system/partition first, and another event to set thesystem/partition to a different part set level. For example, if event Apart sets the system (or a partition), you cannot program event B to fullset the system. You must program event B to unset the system andthen use event C to full set the system. If you create an event to unset a partition, and another event to set thesame partition again, you must program the setting event to occur atleast 10 minutes after the unsetting event. The control unit adjusts its clock in Spring and Autumn to allow forSummer Daylight Saving Time. At the Autumn change-over, avoidconfiguring any unset events to take place during the changeover timeon 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 the control unitunsets any part of the system at these times, it will NOT set thesystem again when the clock changes back to Winter Time.Manually setting and unsetting partitions does not alter the timesprogrammed in calendar sets. If a user sets a partition that is due to be setby a calendar event, the partition remains set when the calendar event timeis past. Likewise, if a user unsets a partition before a calendar event is dueto unset the partition, the partition remains unset.Add EventUse System Config – Calendar Set – Add Event to create an event. Whenyou select the option, the control unit will guide you through the followingseries of options:Event Name Enter up to 12 characters or press to leave thedefault name.
