Softener regenerates too frequently, causing excessive salt and water consumption

Safety first: No hydraulic work is required; adjustments are via the controller.

• Review water analysis: Confirm the actual raw water hardness from a recent test or lab report.
• Check settings: Enter the installer menu and verify that hardness and capacity are correctly programmed for the Viessmann softener model and household usage.
• Inspect flow sensor: Ensure the flow sensor is installed correctly and not subject to vibration that could cause false pulses.
• Monitor usage: After adjustments, monitor regeneration frequency over several days. If still excessive, the flow meter may need replacement.
