4. After powering on, use the keys to set the control mode and test if the automatic start/stop function operates normally.

Frequently Asked Questions (FAQ)

Q1: Can the timer mode be set for specific time?

A1: The built-in cycle timer operates on "Run Duration + Stop Duration". For specific time-of-day scheduling, an external 24-hour timer can be added.

Q2: After a sudden power outage, does the controller need resetting?

A2: No reset needed. This IP65 ABS outdoor smart pump panel features power-off memory and will automatically resume operation with the last settings once power is restored.
