The York 331-02507-601 Board Kit is the essential Variable Speed Drive (VSD) logic control solution for YCAV series air-cooled screw chillers. Engineered specifically for 2-compressor configurations, this kit is mandated by the manufacturer whenever a logic board replacement is performed. Unlike standalone boards, this comprehensive OEM replacement kit includes the required EPROMs and PWM generator (components 59 and 171) to ensure full communication between the drive logic and the chiller’s control center. In the field, using the 331-02507-601 prevents common synchronization errors and ensures the Variable Speed Drive accurately modulates compressor frequency based on real-time load demand. This precise HVAC frequency control is critical for maintaining high part-load efficiency and protecting the compressor motor from thermal stress. Designed for 60Hz YCIV and YCAV models, this direct-fit chiller control board maintains the integrity of the original factory sequence of operation without needing external modifications.

• Full System Integration: Includes EPROMs and PWM generators required to sync with York YCAV chiller software versions.
• VSD Performance Optimization: Ensures accurate modulation of the variable speed drive for superior energy efficiency.
• OEM Reliability: Direct York 331-02507-601 board replacement ensures compatibility with existing 2-compressor chiller logic.
• Plug-and-Play Compatibility: Designed for standard 60Hz applications to match factory electrical specifications.

Is the 331-02507-601 compatible with single-compressor YCAV units?
No, this specific kit is optimized for 2-compressor YCAV and YCIV systems. For single-compressor configurations, a different part number is required to match the board's logic to the drive hardware.

Does this kit include the EPROM chips?
Yes, this VSD logic board kit includes the necessary flashing components to restore full functionality to the chiller control panel immediately after installation.

Why can't I just replace the board without the full kit?
York engineering guidelines state that when the logic board is replaced, the associated PWM generator and software chips must be updated simultaneously to prevent communication failures within the Variable Speed Drive.
