Your zone 3 watered several times per day and it is smart watering. Some zones are watered multiple times a day, you probably selected clay, clay loam or loam as the soil type which accepts water slowly, often as little as 1/4 inch per hour and that is why we break the watering into many pieces to avoid water runoff.
We found your smart watering is advanced and in this level, Netro smart watering will add smart zone schedules for you if Netro think the watering is not enough.
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. ( Settings->Zones->Smart Zone)
