Overview
This Sundance® PWA Control Assembly is the complete OEM equipment pack used in 2002 and newer Maxxus® spas configured with:
- 2‑Pump hydrotherapy system
- PermaClear® UV water management
-
NT‑Series Sundance® control architecture (New Technology platform)
The assembly integrates the system circuit board, heater terminals, sensor inputs, PermaClear UV logic channels, and circulation/heater sequencing for all Maxxus® builds produced after the 2002 upgrade cycle.
This PWA replaces several early 880 Series electronics packages (6600‑0xx family) and allows full compatibility with the Maxxus® dual‑pump jet layout and the PermaClear® sanitation system.
Compatible Spa Models & Years
✔ Sundance® 880 Series
Maxxus® — 2002 through early 2008, and service‑replacement compatible through later NT years.
The 2002 redesign introduced:
- PermaClear® UV
- Updated NT‑series logic boards
- The first generation of modular Sundance® PWAs
This assembly is used in:
- Maxxus® 2002
- Maxxus® 2003
- Maxxus® 2004
- Maxxus® 2005
- Maxxus® 2006
- Maxxus® 2007
- Maxxus® 2008 (pre‑Smart Logic revisions)
These spa years mapped to the early NT logic boards 6600‑094, 6600‑098, 6600‑155, 6600‑160, all listed as part of the same PCB family.

Purpose & Performance
The PWA Control Assembly (2‑Pump, PermaClear) manages:
- High‑flow Maxxus® dual‑pump hydrotherapy
- 5.5 kW heater sequencing & safety shutoffs
- UV PermaClear® sanitation timing & indicator lights
- Low‑speed circulation and filtration cycles
- LCD topside logic, including error logs
- Temperature control & monitoring
Replacing an aging NT‑series control box resolves:
- No‑heat conditions
- Intermittent pump operation
- UV indicator faults
- FLO / OH / ILOC logic problems
- Topside display communication failures
