Overview

Parts 6600‑830 and 6600‑860 are OEM Sundance® 2‑pump control panels used on 2001 and newer Sundance® 850 & early 880 Series hot tubs. These topsides provide full control of the spa’s two‑pump hydrotherapy system, lighting, temperature settings, filtration cycles, readiness modes, and system status.

Both part numbers are functionally equivalent, with 6600‑860 serving as the updated OEM revision of the original 6600‑830.

These panels are specifically designed to match the Sundance® 850/880 topside cutout and communication protocol for spas produced in the mid‑2000s through early 2010s.
