The 63T-AC83T-KIT is a universal remote control kit designed to replace the Harbor Breeze A25TX013 TX013-R and upgrade most AC 3-speed ceiling fans with modern remote operation. It delivers fan speed control across Off/Low/Medium/High settings, light ON/OFF with dimming capability, and a timer delay shut-off function. The compact receiver mounts inside the fan canopy for a seamless integrated appearance and is compatible with incandescent, LED, CFL, and E-ballast bulbs.
