Tecmark Overlay [Digital Command 3 Btn] (30217BM) is a replacement topside panel overlay designed for spa control panels that need a clean, readable control face. This overlay helps refresh the appearance of the control area while keeping button labels and command positions easier to identify during normal spa operation. Topside overlays are important service parts because worn, cracked, faded, or peeling labels can make a spa panel harder to use and can take away from the finished look of the equipment. This Tecmark overlay is intended for matching Command Center or Digital Command configurations, making it a useful option when restoring an existing panel rather than replacing more equipment than necessary.
