Rulwiz Madam, you can only run one quick run at a time. If I am right, you must runned schedule1 and then click another schedule's quick run. But that's not gonne work. Let me give you an example. Let's say you create two schedules, schedule 1 contains one zone and runs for five minutes. schedule 2 contains one zone and also runs for five minutes.
You first click on "Quick Run Schedule" for schedule 1 and schedule 1 starts to run. Then you exit and click on "Quick Run Schedule" for schedule 2. At this point schedule 1 is forcibly terminated and schedule 2 starts. It is not as you might think that after the execution of schedule 1, schedule 2 will follow.
You can only wait for schedule 1 to finish and then click on "Quick Run Schedule" for schedule 2 so that there is no conflict.
If you want to run Quick Runs for more than one zone, it is recommended that you simply use Quick Runs for zones and add all the zones that need watering.
