York S1-331-03019-000 Conversion Kit

When you're upgrading older rooftop units (RTUs), the York S1-331-03019-000 Conversion Kit is the industry standard for integrating the Honeywell JADE W7220 economizer platform. This OEM-certified economizer controller kit is engineered to replace legacy W7212 systems, providing a digital interface that eliminates the drift issues associated with old-school potentiometers. As a veteran-grade HVAC replacement part, it handles everything from basic dry-bulb changeover to advanced differential enthalpy control when paired with Sylk Bus sensors. The JADE module at the heart of this kit ensures your site stays compliant with IECC, ASHRAE 90.1, and California Title 24 requirements through its integrated fault detection and diagnostics (FDD). By modernizing the HVAC control logic, this kit optimizes outdoor air intake and compressor cycling, significantly reducing mechanical wear while improving energy efficiency in commercial applications. This is a direct-fit solution for York rooftop units, designed to simplify setup with its backlit LCD and push-button configuration.

• Digital Precision: Replaces inaccurate analog potentiometers with a digital economizer module for precise setpoint management and thermal comfort.
• Code Compliance: Built-in FDD (Fault Detection and Diagnostics) ensures the system meets modern energy codes and reduces maintenance callbacks.
• Enhanced Connectivity: Features a 2-wire Sylk Bus interface that simplifies the wiring of enthalpy and CO2 sensors for Demand Control Ventilation (DCV).
• Universal Versatility: Supports single-speed or two-speed fan operation, making it a flexible York HVAC part for various light commercial RTU configurations.

Is the S1-331-03019-000 a direct replacement for the S1-031-02971-000?
Yes, this conversion kit is the recommended upgrade path for the older S1-031-02971-000 and W7212 series controllers, providing modern digital logic and improved status monitoring.

Does this kit require specific sensors for enthalpy control?
For enthalpy-based changeover, you must use Honeywell Sylk Bus sensors (like the C7400S). The module will automatically detect these sensors upon power-up via the digital communication bus.

Can I use this for Demand Control Ventilation (DCV)?
Yes, the JADE controller supports CO2 sensor integration (2-10 VDC or Sylk Bus) to modulate dampers based on occupancy levels, optimizing indoor air quality and efficiency.
