Safety first: Ensure the system is safe to restart (no drained lines or closed valves) before enabling auto-restart.

Check controller settings: In the Calpeda controller menu, look for an auto-restart or power-fail restart option and enable it if appropriate for your installation.
Verify external control: If the pump is controlled by an external timer or automation, confirm that it resumes sending a run command after power is restored.
Clear stored faults: Some controllers require manual fault acknowledgment after a power event. Clear any alarms and test restart behavior.
Test RTC/timer: Ensure the internal clock and schedules are correct. Replace the controller if the clock fails to keep time or schedules do not execute.
