York S1-031-03000-000 Enthalpy Sensor

The York S1-031-03000-000 Enthalpy Sensor is a critical component for optimizing HVAC economizer systems by measuring both latent and sensible heat in the outdoor air stream. Designed for precision air enthalpy control, this sensor ensures the rooftop unit (RTU) utilizes free cooling only when the outdoor air's total energy content is lower than the return air. This OEM York replacement part serves as the direct successor to the S1-031-00863-000, featuring improved resistance to environmental contaminants and drift. For a service technician, this means reliable demand control ventilation and reduced compressor cycling. The sensor integrates seamlessly with Johnson Controls and York logic controllers to automate the indoor air quality and efficiency of the system. By monitoring relative humidity and dry-bulb temperature simultaneously, the S1-031-03000-000 provides the accurate data required for modern building automation systems to maintain peak thermodynamic performance.

• Direct OEM Replacement: Engineering match for S1-031-00863-000, ensuring standard mounting and wiring compatibility without field modification.
• Advanced Enthalpy Control: Accurately calculates the heat content of the air to maximize energy efficiency during free cooling cycles.
• Rugged Construction: Built for high-exposure environments, providing stable humidity sensing and temperature readings over an extended service life.
• Optimized Compatibility: Designed specifically for York RTU units and compatible economizer frameworks.

How do I verify if this enthalpy sensor is compatible with my existing York unit?
This sensor is a direct replacement for part S1-031-00863-000. You should verify the part number against your unit’s service manual or check the wiring schematic for standard enthalpy input requirements.

Can the S1-031-03000-000 help reduce energy costs in commercial applications?
Yes, by accurately sensing the energy level of outside air, it allows the economizer to shut down the compressor and use 100% outdoor air for cooling when conditions are favorable.

Does this sensor require specialized calibration before installation?
As a factory-calibrated OEM part, this enthalpy sensor is designed for immediate integration into the system logic without the need for manual field adjustments.
