Mini-Split Wired Wall Controller R-454B Advanced Control Ductless Compatible KSACN1401AAA

The Mini-Split Wired Wall Controller R-454B Advanced Control Ductless Compatible (KSACN1401AAA) is a wired wall-mounted controller intended for select R-454B ductless mini-split systems that support expanded control functionality. This controller provides permanent zone-level access to temperature setpoint control, operating mode selection, and fan operation as enabled by the connected indoor unit’s control board for R-454B refrigerant systems. The wired design uses low-voltage communication wiring, mounts to a standard wall box, and removes the need for batteries or line-of-sight operation. For proper job fit, technicians must verify the indoor unit is an R-454B model approved for advanced wired control, confirm communication compatibility, check wiring polarity, and ensure correct addressing during commissioning. Using the advanced R-454B controller supports full utilization of next-generation ductless system features and helps prevent communication faults or control limitations caused by legacy controller substitution.
