The Hydronext 5600 S is a high-efficiency, fully automatic water softener control valve system. It is widely utilized in residential and light commercial applications to reduce water hardness (calcium and magnesium ions) through ion exchange. The system is notable for its "S" designation, which typically refers to its specific layout or a "Side-mount" configuration, though it is often used as a compact replacement for older timer-based systems. | Symptom | Probable Cause | Manual Solution
