🛁 ACC KP-2105 Topside Control Panel – 5-Button Compact Oval Main Control with LED Display
Compact oval main topside with LED display and essential 5-button control for ACC Uni-Pack systems
🎛️ Product Overview
The ACC KP-2105 Topside Control Panel is a compact 5-button main control featuring a unique oval design and LED display. Manufactured by Applied Computer Controls (ACC), this American-engineered panel offers essential spa control functionality in an ultra-compact form factor measuring just 114 × 50 mm.
This panel features an LED display for temperature and status readout, with dedicated buttons for Time, Temp, Light, Jets, and Set functions. The compact oval design makes it ideal for spa installations where space is limited or where a smaller, more discreet control panel is preferred. Unlike the larger rectangular KP series panels, the KP-2105 provides a streamlined alternative without sacrificing core functionality.
The KP-2105 connects to ACC Uni-Pack control systems and provides complete main topside functionality including temperature control, jet activation, lighting, time functions, and access to system settings. The overlay design features no display cut out, providing a clean, integrated appearance.
