This is how you run the entire system or multiple zones on your Hydrawise controller. While you're on the home page, you got this gear right up here, hit that. Top option is run all zones, hit that. Now, you can either just hit run now and that's how you mainly run the entire system from start to finish or blue means your watering, white means you're not. So let's say you don't want to run all of them, but maybe there's like, three or four or depending on how many zones, maybe if half you wanted to run. Then just hit run now. No, come on, based on the ones that you chose and that's it.
