@TechFan: you definitely have a point. But let me justify it by saying that at least for now there is strong incentive to break up long water time to smaller sessions, because of a limitation in the scheduling algorithm. Specifically, if in the middle of a program-run the controller restarted (say, due to power down), it will not resume the program even if it hasn’t finished the program yet. This is because the algorithm only starts a program if the current time matches the program’s start time or any of the repeat times. Say, if a program starts at 8:00am, and the controller subsequently powers down and comes back at 8:01, it won’t resume the program because it’s already one minute past the start time. So if the program is supposed to water for 6 hours, this will lose almost the entire 6 hours. On the other hand, if you set the program to water for 1 hour and repeat 6 times, it will at most lose 1 hour, because at 9:00am the program will start again. Hope this makes sense.

We are currently away till Monday July 21. Orders placed during this time will be shipped on Tuesday July 22. Thank you for your understanding!
