• Dual Compressor Logic: Pre-configured for 2-compressor chiller systems to manage balanced staging and lead-lag cycles.
• VSD Integration: Optimized communication interface for York variable speed drive frequency control.
• Reliable Data Processing: High-speed processing of sensor inputs for accurate chiller performance monitoring.

Common Questions

How do I confirm if this logic board kit is compatible with my specific YCIV model?
Compatibility is determined by the chiller serial number and the number of compressors. This board is specifically designed for two-compressor YCIV screw chillers utilizing a VSD architecture. Always verify the part number on the existing board matches 331-02507-603 before installation.

What are the signs that a York VSD logic board requires replacement?
Common indicators include persistent communication errors between the micro-panel and the VSD, failure of the compressor to ramp up frequency, or "Board Not Responding" fault codes. If the drive gate signals are verified but the logic output is inconsistent, the logic board kit may be compromised.

Does this kit require specialized programming in the field?
While the hardware is direct-fit, professional technicians must verify that the chiller control settings and firmware versions are synchronized with the existing micro-panel to ensure full functionality of the VSD logic board.
