Product Q&A

Q:Does the B603PRO require complex parameter setup?

No. It features a factory-preconfigured Constant Pressure Macro that allows one-touch operation. Users only need to connect a pressure sensor and set the target pressure, cutting setup time by 90%.

Q:How does the controller handle dry-run protection?

It uses patented intelligent dry-run protection that detects conditions via motor current and torque algorithms. It automatically stops the pump and attempts scheduled auto-restarts, eliminating the need for external liquid level sensors.

Q:Can multiple pumps be controlled without a PLC?

Yes. The B603PRO supports master-slave multi-pump control for up to 6 units via a single RS485 line. It automatically manages duty/standby rotation and auto-staging, removing the need for external PLCs.

Q:What are the typical application scenarios?

It is suitable for residential and high-rise building water supply, commercial and industrial water cycling, smart agricultural irrigation, and pump OEM integration for direct factory mounting.

Q:What safety protections are built-in?

The controller includes safeguards against pipe bursts, over-pressure, low-pressure, freezing, scaling, and features automatic sleep/wake modes based on water demand.
