Mini-Split Wired Wall Controller 7 Day Programmable Thermostat High Wall Mid Tier Ductless Compatible KSACN0901AAA

The Mini-Split Wired Wall Controller 7 Day Programmable Thermostat High Wall Mid Tier Ductless Compatible (KSACN0901AAA) is a hard-wired wall-mounted programmable thermostat designed specifically for mid-tier high wall ductless mini-split indoor units that require enhanced scheduling and permanent zone-level control. This controller connects via low-voltage communication wiring and provides 7 day programmable scheduling, temperature setpoint control, operating mode selection, and fan speed adjustment as supported by the connected ductless indoor unit. Unlike entry-level wired controllers, this model is intended for mid-tier high wall applications, aligning its firmware and control logic with indoor units that support expanded comfort and scheduling features. For proper job fit, technicians must verify the indoor unit is a compatible high wall mid-tier ductless model, confirm support for programmable thermostat functionality, check wiring polarity and communication protocol, and ensure correct controller addressing during setup. Installing the correct mid-tier programmable wired controller delivers consistent scheduled comfort, eliminates battery maintenance, improves long-term control reliability, and reduces callbacks caused by mismatched controller capability or unsupported scheduling features.
