Is there a scheduling option to run on my Gen 2 (2.6) for:
1. Fixed Days
2. Using ET data from our local weather station to determine run duration (minutes).
I want to water deeply for a duration that replaces ET since the last irrigation but I don't want the sprinklers to run whenever they want. I don't want sprinklers running before I mow or just before an outdoor lawn party. I also don't want them running for a short duration as I want to encourage deep root growth with deep watering (longer run times).
I live in the Central Valley in CA where summer temperatures (ET) can vary considerably day to day with essentially no rain between April and November. For this reason I don't want to use historical weather data for my run times.
A specific example of something I'm familiar with is the Weathermatic SL 1600 timer with a SLW5 weather monitor. This unit sends nightly ET info to the timer and if no watering is scheduled for that day the ET data ("run time") is put into memory and accumulates until the next scheduled run day. Then on the next scheduled run day ET since the last watering is basically applied to replace what transpired and evaporated over that period. of time.
To complicate things a bit I have two Gen2 units on my property with 25 zones, with multiple sprinkler/drip types, which makes available hours in the day to run a challenge.
