Hi Maureen,
You can choose "customized" mode to adjust watering by providing the preferred moisture level and flow rate of your sprinklers. Please go settings->zones->specific zone number->smart zone-enabled->Mode. The manul run button is in the home page, below the Netro logo, there is task bar "online", "battery percentage", "manual run", "rain delay".
Thanks,
Wency
