Why is the rain delay 0% on display? May 17, 2018 at 7:16 am #50025 RayKeymaster Maybe you selected ‘auto rain delay’ as the weather algorithm?

May 17, 2018 at 11:30 am #50058 RayKeymaster It’s up to you: if you want it to be more automatic, use either the Zimmerman or auto rain delay. If you want full control over the watering percentage, set it to manual and change the watering percentage yourself.
