York S1-331-02997-000 Control Kit

The York S1-331-02997-000 BAS Simplicity Control Kit is a direct OEM replacement part engineered for building automation system (BAS) integration in York commercial HVAC units. Designed to replace the legacy S1-331-02962-000, this kit facilitates seamless communication between the rooftop unit (RTU) and the facility's supervisory controller. This HVAC control board kit is critical for managing Modbus RTU or BACnet MS/TP protocols, allowing for precise sequencing of cooling stages, heating cycles, and economizer operations. As a technician, you know that Simplicity Elite and Smart Equipment (SE) platforms require accurate firmware configuration. This kit ensures that your unit controller accurately interprets sensor data—such as supply air temperature (SAT) and outside air temperature (OAT)—to maintain optimal discharge air setpoints. Utilizing a real OEM control board prevents common communication failures and nuisance low voltage alarms often seen with generic alternatives. This kit is compatible with popular York 2NH, 1LD, and 2ML commercial series units.

• Direct OEM Replacement: Ensures exact fit and immediate compatibility for York S1-331-02997-000 and S1-331-02962-000 part numbers.
• BAS Protocol Support: Enables high-level communication for Building Automation Systems using BACnet or Modbus.
• Optimized Performance: Enhances economizer control and multi-stage compressor sequencing for improved energy efficiency.
• Durable Circuitry: Built with industrial-grade components to withstand vibration and voltage fluctuations typical in commercial RTUs.
• Advanced Diagnostics: Integrates with the York Simplicity Linc system for faster troubleshooting of sensor faults and lockout codes.

• Does this board require field programming? While it comes with base firmware, you must verify the addressing scheme and configuration parameters (such as fan delays and stage counts) via the MAP Gateway or onboard joystick to match your specific equipment model.
• Will this fix a communication lost alarm? In many cases, yes. This kit replaces the interface translator often responsible for packet loss between the HVAC unit and the BAS network.
• Is the replacement process plug-and-play? The physical installation is straightforward with standard harnesses, but we recommend performing a Backup and Restore of parameters from the previous SE controller to a thumb drive to ensure all setpoints remain consistent.
