I'm building a rate and had a question about the E+ documentation file. Specifically the utility example files, Example F. Here's what they're trying to model:

The on-peak period is defined as the hours starting at 10am and ending at 7pm, Monday through Friday for June through September and 3pm to 10pm Monday through Friday for October through May. All other hours are considered off-peak.

But here's what the example IDF looks like:

Schedule:Compact, TwoSeasonSchedule, number,
Through: 5/31, For: AllDays,  Until: 24:00, 1,
Through: 9/30, For: AllDays,  Until: 24:00, 3,
Through: 12/31, For: AllDays, Until: 24:00, 1;


Schedule:Compact, TimeOfDaySchedule, number,
Through: 5/31, For: AllDays,  Until: 15:00, 3,
                              Until: 22:00, 1,
                              Until: 24:00, 3,
Through: 9/30, For: AllDays,  Until: 10:00, 3,
                              Until: 19:00, 1,
                              Until: 24:00, 3,
Through: 12/31, For: AllDays, Until: 15:00, 3,
                              Until: 22:00, 1,
                              Until: 24:00, 3;

The TwoSeasonSchedule makes sense to me, but the TimOfDaySchedule doesn't make sense. Can someone explain how the 1's and 3's at the end of the TimeOfDaySchedule work? Why would days before May 31st and before 3pm be given a summer schedule, and then a winder schedule until 10pm, and then back to a summer schedule until midnight?

I'm guessing I'm reading this wrong, but I'm hoping someone can clarify it for me.

Thanks! Eric
