Autotrol 255 Cycle Overview

The Autotrol 255 control valve executes a programmed cycle to effectively soften water and maintain optimal performance. This cycle typically includes several distinct stages: service, backwash, brine draw, brine rinse, and refill. During the service stage, softened water is delivered for household use. The backwash phase cleans the resin bed, removing accumulated impurities.

Next, the brine draw stage pulls brine from the brine tank to recharge the resin. Following this, the brine rinse stage flushes remaining brine from the resin bed. Finally, the refill stage replenishes the brine tank with water and salt, preparing for the next regeneration cycle. Understanding this sequence is crucial for diagnosing potential issues and ensuring efficient operation. The duration of each stage is programmable, allowing customization based on water hardness and usage patterns.

Regeneration Cycle Explained

The regeneration cycle is the heart of the Autotrol 255’s operation, restoring the resin bed’s softening capacity. It begins with backwash, reversing water flow to loosen debris. Subsequently, the brine draw phase initiates, pulling a precise amount of brine solution from the brine tank through the injector. This brine replaces calcium and magnesium ions on the resin with sodium ions.

Following brine draw, the brine rinse stage slowly flushes excess brine and displaced hardness minerals to drain. Finally, the refill stage replenishes the brine tank with water, dissolving salt to create the brine solution for the next cycle. Proper regeneration is vital; insufficient brine leads to hard water, while excessive brine wastes salt and water. Cycle timing and brine concentration are adjustable settings, impacting efficiency and water quality.

Bypass Valve Operation

The bypass valve is a crucial component, allowing water to flow around the softener without treatment. This feature is essential for maintenance, repairs, or when softened water isn’t required – like watering lawns. The Autotrol 255 bypass typically consists of three valves: an inlet, an outlet, and a bypass.

Turning the valves to the bypass position directs water directly through, bypassing the resin tank. This prevents water from flowing through the softener during servicing. Always use the bypass before attempting any repairs. It’s also useful if you experience a problem with the softener, providing untreated water while troubleshooting. Refer to the valve markings for proper operation and ensure a complete seal when returning to service mode.
