Question
I bought a home with a 5 zone outdoor sprinkler system with a Nelson SmartZone EZ controller. The controller is dead. AC in is ok but no indication of function. Tried reset, power down, battery change and no results. I guess I will replace it. Nelson must be out of this product as I can't find it anywhere. I guess I will replace it with another brand. Are they all compatible? Any recommendations?

Answer
Hey John, yeah almost all the controllers are compatible. I would suggest installing a
Irri-trol "Rain dial" controller. They come in 6,9,or 12 station controller. They are easy to program and should last a long time. Just make sure when you pull the old field wires off the old controller, that you mark them as you take them off #1,#2 etc. and especially the common (C) wire, and then put them back on the new one exactly as they were taken off the old one. Good luck and have a great day.
