Advanced Features and Settings
Aqua Systems softeners offer customizable settings like Demand Initiated Regeneration and adjustable frequencies. These features optimize efficiency, unlike aquarium lighting adjustments.
Demand Initiated Regeneration (DIR) Explained
Demand Initiated Regeneration (DIR) is a smart feature in Aqua Systems water softeners. Unlike timed regeneration, DIR monitors your actual water usage. The system calculates hardness depletion and initiates a regeneration cycle only when necessary, maximizing salt and water efficiency. This contrasts with fixed schedules that often regenerate even with minimal water consumption.
DIR utilizes a sophisticated algorithm, tracking water passed through the softener. When the system determines a pre-set capacity has been reached – meaning a specific amount of hard water minerals have been removed – it triggers regeneration. This intelligent approach reduces wasted resources and lowers operating costs. Understanding DIR is key to optimizing your softener’s performance and enjoying consistently soft water. It’s a significant advancement over older, less efficient regeneration methods.
Adjusting Regeneration Frequency
Adjusting regeneration frequency on your Aqua Systems softener allows customization for optimal performance.
