Pump will not start at scheduled times but runs when started manually

Safety first: Ensure the pump area is dry and safe while you work on the control panel.

• Verify clock: Check the current time and date on the Saci pump display and correct if necessary.
• Review programs: Enter the programming menu and confirm that start/stop times are enabled and not overlapping or set to zero duration.
• Check power stability: Frequent power cuts can reset the clock. Consider using an external timer or UPS for the control circuit if outages are common.
• Test schedule: Set a short test program a few minutes in the future and observe whether the pump starts automatically.

If manual operation works but schedules never run, the internal timer circuitry may be faulty and the control PCB may need replacement.
