The blue wire disables the seasonal adjustment. You set the percentage and it stays there. I just removed my Hunter and replaced it with a Rachio controller. It's controlled by wi-fi with your smart phone or computer. Links up to an official weather station or personnel one, and adjusts watering by past, present or future forecasts, or lets you decide manually. Sends me text alerts when ever it waters, the time and amounts. Also, you can run 1 zone at a time thru your phone to test your nozzles.
And, Pooh and Mike.........it works with Alexa!
