What causes this fault?
This status occurs when the boiler's internal control knobs or settings have been moved while the system is in its configuration mode. The flashing light indicates that the boiler has detected a change in its operating parameters and is waiting for a manual confirmation to store these new settings. It effectively pauses operation until you acknowledge that the adjustments were intentional.
