Smart Water Pump Controller
(Single-phase / Three-phase, One-Control-One & One-Control-Two)

Application Scope:
Suitable for high-rise water supply, underground sewage drainage, and deep well pumping systems.

Main Features:
• Supports one-in-use / one-on-standby mode, dual-pump alternation, and dual-pump simultaneous start at ultra-high water level.
• Real-time display of voltage, current, and water levels (upper & lower tanks).
• Manual/Automatic switchable control with one button.
• Fault cause display with audible and visual alarms.
• Supports upper tank filling, lower tank drainage, and constant pressure water supply.
• Comprehensive protection: dry-run, overload, locked rotor, phase loss, short circuit, over/under voltage.
• Automatic restart after voltage returns to normal.
• One-key setup for overload and dry-run protection.
• Manual/Auto start-stop; Timed start-stop; Power-on auto restart.
