Dear customer,
Depending on the selected sprinkler type, the default flow rate in different Modes is different. The default value is 38.1
If you want to customize the flow rate, you can go to Settings->Zones->Smart Zone, choose Customized mode, and you can set the Flow Rate.
If you have any further concerns or questions, please do not hesitate to reach out to us.
Thanks,
Wency
