Description:
York YLS-001 (025W42574-000, SAP:552890) is a dedicated main control board for York YLS series industrial chillers, designed to manage key system operations including compressor start-stop and load regulation, condenser fan speed control, refrigerant flow adjustment, and real-time system status monitoring. It adopts a multi-layer FR-4 PCB combined with through-hole and surface-mount hybrid assembly processes, integrated with high-reliability microcontrollers, dedicated memory chips and multi-channel I/O modules. This structure ensures stable signal transmission and program operation in harsh industrial environments with high temperature and humidity. Its core functions cover executing the chiller's overall control logic, processing temperature, pressure and other key sensor signals, coordinating the linkage of compressors, fans, valves and other components, conducting fault self-diagnosis and alarm, and supporting software upgrades via EPROM replacement. It is fully compatible with York YLS series chiller control systems, and is the preferred OEM replacement part for maintenance and repair of the unit's control system, with reliable quality and stable performance.
