Generating a Time Program, Special Day List

EXCEL 50/100/500/600/800

TIME PROGRAMS

Entries in the annual program must therefore be made only if a daily program differing from the one selected is to be used. An undefined daily program to be inserted in the annual program can be defined in the daily program.

Special Day List

One special day list exists per time program. It makes a number of holidays and special days available to which a daily program can be assigned. This daily pro- gram will then apply to this holiday or special day every year. The date of floating holidays is calculated automatically by the Excel 500. If no daily program is entered on certain holidays, the special day list is not taken into account on this day.

The following holidays and special days are contained in the list:

•New Year's Day (1st of January)

•Epiphany (6th of January)

•Monday before Ash Wednesday

•Shrove Tuesday

•Ash Wednesday

•Good Friday

•Easter Sunday

•Easter Monday

•Labor Day (1st of May)

•Ascension Day

•Whit Sunday

•Whit Monday

•Corpus Christi

•Assumption Day (15th of August)

•Day of German Unity (3rd of October)

•Reformation Day (31st of October)

•All Saint's Day (1st of November)

•Day of Prayer and Repentance

•1st to 4th Sundays in Advent

•Christmas Eve (24th of December)

•Christmas Day (25th of December)

•Boxing Day (26th of December)

•New Year's Eve (31st of December)

•First Saturday in the month (Germany)

If a daily program that has not yet been defined should be entered in the special day list, it must first be defined in the "Daily program" section of the time program.

NOTE: To activate the special day list, you must set the special day status to

ON.

The "TODAY" Function

Using the "TODAY" function, it is possible to perform on/off changes to setpoint values or control states without having to access the annual program or to define a new daily program. New setpoint values or control states and the period of validity (i.e. start and end) for a specific user address are defined. These changes are carried out at operator level 2 of the XI581 (not with XCL5010, Excel 100C), XI582, and XL-Online operator interfaces or the Excel 50 MMI. The start time must be within 24 hours from the entry time. The end time must be within 24 hours from the start time. The duration of the change can thus amount to a maximum of 24 hours. The entry is deleted automatically after the end time point is exceeded.
