Prior to this version, 100% meant watering 100% of set watering times. Now, it says 100% means watering twice as long. If you want to water for 10 minutes on certain zones, set the timer for 10 minutes but seasonal adjust to 0%. If you set for 50%, will water for total of 15 minutes.

For some older models, it followed Hunter brand seasonal adjust where 100% meant exactly the same watering time as the set valve time. Confusing!

If you are confused like me then... set the timer for 1 minute run duration and sat the seasonal adjust to 100%. Does it run for 1 minute and shut off or does it run for 2 min? Let me know of your findings please.
