The Balboa BP7 Retrofit Kit (BBG6406 / G6406) is the ultimate all-in-one spa control system upgrade, delivering modern technology, flexible configuration, and rock-solid reliability to virtually any hot tub. Engineered by Balboa Water Group — the industry leader in spa controls — this 4kW kit replaces outdated systems with ease and comes complete with the TP600 topside panel, M7 heater assembly, and everything you need to get your spa running like new.
🚩 PRO TIP: The BP7 defaults to "Setup 21" (one 2-speed pump). Before powering on, verify your component voltages and spa configuration using the wiring schematic on the back of the spa pack cover. Refer to the included installation guide or the Balboa BP7 Configuration Instructions for your specific pump/blower setup.
