The 4 kW 3-Load Spa Control System is a premium spa control solution designed for high-demand, multi-load spa setups. Operating on 240V, this system supports up to three loads—typically two pumps and either a blower or circulation pump—making it ideal for spas that require advanced hydrotherapy options. It features a powerful 4.0 kW heater for consistent water temperature, and the included ML700 Spaside Control Panel provides an intuitive interface for managing all major functions. Designed for outdoor reliability, the unit includes freeze protection, Smart Winter Mode, and a triple powder-coated metal enclosure to withstand harsh environments while promoting energy efficiency and long-term performance.
