This remote control is a direct substitute for the Hunter 99118 IN2TX40 model, designed to work seamlessly with compatible Hunter ceiling fans. It features a standard transmitter and receiver kit configuration that enables wireless control of fan speed and light dimming functions. The 63T-AC83T-KIT designation identifies this as a complete replacement solution for fans originally equipped with the IN2TX40 remote system. Installation is straightforward, requiring only basic connection to your existing fan's receiver module.
