The sprite worked perfect for about 3 weeks. Went out of town for a week, during that time it snowed for the entire duration of my trip. The unit worked as it should and didnt water. However when it should have picked up its schedule after weather cleared it did not. It will not run its zone at all. I have checked the resistance on all zones solenoids and they are fine at 28 ohm. I reconnected my old hunter system and all zones worked properly with that controller. So whats the next step?
