ACC Topside Control Panel – LX‑2020
The ACC LX‑2020 is a SmarTouch SmartTouch Digital oval topside control panel by Applied Computer Controls (ACC), designed to manage single- or dual-pump spa systems with auxiliary control. Featuring a clear LED display and seven well-organized buttons, it offers full control of spa functions—including temperature, pumps, lights, auxiliaries—and provides diagnostic readouts for efficient troubleshooting.
Product Overview
The LX‑2020 measures approximately 9″ × 3.5″ (229 mm × 89 mm), with a cut-out size around 7.14″ × 2.94″. It includes a 14-pin Mate ‘N’ Lock ribbon cable (roughly 5 ft) for plug-and-play installation with ACC SmarTouch Digital packs (SMTD‑2000/3000, UniPack, etc.) and Acura controllers. The panel is coated for resistant use in spa environments.
Buttons include Temp Up, Temp Down, Light, Aux, Jets, Aux2, and Set, with succinct labelling to simplify spa navigation.
System Compatibility
The LX‑2020 is fully compatible with ACC SmarTouch Digital systems such as SMTD‑2000, SMTD‑3000, UniPack, and Acura controllers. It replaces earlier keypads, including KPL‑2020. While header connectors and dimensions match typical ACC setups, it’s critical to verify part numbers to ensure right fit and operation.
