Hi John,
If you want to create your own programs and turn off smart zone feature and rain delay feature, please go to Settings->Zones->Smart Zone and toggle the enable button. When the smart zone is disabled, the system will strictly follow the user program to water the zones. There is no intelligence here. Netro will not skip your schedules when there is rain. Regulation feature will not be in effect as well.
If you want to keep the smart watering feature. To adjust smart watering, please go to settings->zones->select a zone->smart zone and choose your preferred watering mode. We recommend you to choose boost mode to increase the watering amount. You can choose "customized" mode to adjust watering by providing the preferred moisture level and flow rate of your sprinklers.
