Hi, new to OS and I’ve read through the user manual, but can’t figure this out. I have a program set to run 2 zones, each for 30 mins, using Weather Adjustment and Zimmerman method. The first time the program was scheduled to run, the water level was at 40%. The Preview Program that day showed 12 mins/zone (30m*.4). However, each zone ran for 3m36s. I can’t figure out why they didn’t run for 12m each? Thanks for the info.
It’s possible that the water level has changed from the time you saw the program preview to when the program was actually scheduled. One thing you can test is to change the weather adjustment to ‘Manual’ and set to 100% watering percentage. Then see if the program runs full 30 minutes.
