Thanks to the water police, do you know when to start your multi-zoned irrigation system so that it will be finished by a certain time? And, is it made more complicated when you use the seasonal adjustment option? (Just what is 70% of 45 minutes?)
This app will help you calculate the new start time.
Once you have entered your zone run times (0-60 minutes) in the second screen (these numbers are saved), calculating a new start time is made real easy with the use of the time picker or the seasonal adjustment slider. Just change the time or the seasonal adjustment and your new start time is calculated. There is also a zone is running now indicator--a "Running now" statement in the first screen and in the Zone Settings & Info screen, the end time will be displayed in green rather than the usual black.
