Display shows E11 and regeneration does not start at the programmed time

Safety first: No special hazards for this fault, but avoid changing settings without understanding their effect.

Step-by-step checks:

• 1. Verify current time: Check the displayed time and compare with actual time. Adjust using the programming buttons as per the Scalemaster manual.
• 2. Check regeneration time: Ensure the regeneration start time is set to a suitable off-peak hour (e.g., 2:00 AM) and that the unit is in "metered" or "time clock" mode as desired.
• 3. Confirm power stability: If frequent power cuts occur, consider using an uninterruptible power supply (UPS) or ensure the unit’s backup is functioning.
• 4. Manual regeneration test: Initiate a manual regeneration. If this works but timed cycles do not, the clock circuit may be faulty.

If E11 continues and the unit fails to regenerate automatically despite correct settings, the control board may require replacement by a professional.
