Question
I have a Richdel 446 hybrid irrgation controller I live in new York.

Answer
Hey Robert, they longer make this particular controller, and Richdel has been bought out by a competitor. I would suggest installing a "Irri-Trol"  "Rain Dial" controller. It is easy to install and program, and will also last a long time. Check with a local irrigation supply store in your area, and they should carry this unit. Thanks and have a great day.
