Hi Riccardo,
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. 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
