Normally I use a Fully Flexible schedule and that seems to be fine.
However, here in Colorado Springs, we can get much sun (I have a south facing back yard) and so it is recommended that we try to water 1-2 times /per month, even in the winter. But the days to do so aren't predictable, (like today, it's 60 degrees outside, but tomorrow a cold front comes through and it's 45 as the high).
So, what I'd like to do is create a schedule that isn't activated, that I can just hit "Run Now" when the day is nice and I can
turn on the sprinklers.
Here's where I get confused. When this schedule runs, I would like it to do the usual multiple short intervals to prevent runoff (I have silty clay in my backyard, and I have a gentle slope). So, what kind of schedule should I create and how do I program it to make sure it's running each zone several times for a short duration (eg, 3x20m or 4x15m) instead of one long run (1x60m)?
