The outdoor unit mainboard controls all major functions of an air conditioner’s ODU, including compressor drive, fan operation, sensor monitoring, and system protections. It ensures stable performance, efficient operation, and reliable communication with the indoor unit.
Our Split AC control board delivers reliable and precise management of indoor and outdoor unit operations. Designed for inverter and fixed-speed systems, it integrates compressor control, fan speed regulation, sensor feedback, electronic expansion valve management, and intelligent protection logic into a single optimized platform. With support for wired or wireless user interfaces, energy-efficient algorithms, and robust communication between IDU and ODU boards, this controller ensures stable performance, fast cooling/heating response, and seamless compatibility with modern HVAC system designs.
Experience precise, energy-efficient climate management with advanced Mini-VRF control solutions. Designed for multi-zone environments, our controls provide independent room settings, optimized refrigerant flow, and intelligent load balancing for superior comfort and reduced operating costs. Fully compatible with modern building automation systems and available with wired, wireless, and smart app control options.
