why do you have only a 3 hour watering window for ten zones?
the ESP-SMT is a tough controller to program - you have your homework cut out for you, and you get to do the heavy lifting
personally, I think controllers with 80-page instruction manuals are for professional use only, or for homeowners with vast amounts of persistence, and very good reading skills
I do not generally have the opportunity of employing a restricted watering window. Too many lawns have to be covered from a limited water supply, with watering sometimes being restricted to two or three days a week during drought conditions. There have not been any observations of lawn damage from watering over most or all of an overnight period.
I'm scanned the entire manual and can't find an answer.
I also can't confirm that if it does not finish watering in a particular water window it will finish in the next.
Too many factors. It might determine your soil needs more/less water, a "grow period' might be entered.
At this point I'd call Rain Bird at (626) 812-3400 or (520) 741-6100.
I also looked through their FAQ, figuring this problem might show up for others.
Nothing.
If you find a solution we'd appreciate if you tell us what it is.
Thanks.
