I just set up 2 8 zone controllers. I set up 2 Word doc tables, one for each controller. In one column zone, next area, then how often and how long I wanted the zone to run. And the last column the schedule.
I then set up another table for the schedule. I set up this table with the schedule name including which controller, type of schedule, zones in schedule, time for zone, And the last column was when I wanted it to run. This way I could be sure no two schedules would overlap. I then went back to the zone table and entered the schedules. And finally taking the table for schedules programed each controller.
One of the things I read earlier was that if any schedule over laps another schedule the second schedule may not run. So I set my schedules with enough time between to be sure no over lapping.
In the house I sold If any zone schedule overlapped another then the 2nd would not start until the running zone completed it’s schedule.
