This manual introduces the use of the water supply control board SWS.
This manual provides step‑by‑step instructions for installing the SWS water‑supply control base board used with the SAMCO‑vm05 inverter. It includes preparation, mounting, wiring diagrams, terminal descriptions, and the overall wiring layout for the water‑supply system.
The document also details the software function codes, operation modes, PID control, relay‑output functions, and safety precautions required for reliable operation of the water‑pump system. This manual is written in Chinese.
