Hi Michael,
The default setting of Netro watering controller's smart watering level is advanced and your zones will be watered automatically by Netro with smart schedules.
Netro will do everything for you, like skipping smart watering and programs when there is large amount of rain(>0.2inch/ 5.08 mm) or watering regulations and manual restrictions.
If you selected clay, clay loam or loam as the soil type which accepts water slowly, often as little as 1/4 inch per hour, Netro will break the watering into many pieces to avoid water runoff.
If you do not want smart zone schedule to override your own programmed schedule, you can set up the Smart Zone level from Advanced to Basic, which only skip rainning days for your programmed schedule.
For more information about Netro smart watering, here is an article about Netro three watering modes which might be helpful. https://netrohome.com/forum/posts/111
