York 2EC0402 Sensor Kit

Integrate professional-grade monitoring into your HVAC systems with the York 2EC0402 Sensor Kit, a critical component for field-installing dual enthalpy economizer control. Designed for use with 3 to 25-ton single package units, including the ZF, ZJ, and ZR series, this kit enables the Smart Equipment (SE) control board to transition from basic dry-bulb detection to sophisticated enthalpy-based logic. By measuring both sensible temperature and latent humidity, the York 2EC0402 allows the system to calculate the true heat content of the air, ensuring that outdoor air is only utilized for free cooling when it is genuinely more efficient than mechanical refrigeration.

This comprehensive enthalpy sensor kit comes with the necessary wiring harnesses and brackets to facilitate seamless integration into existing economizer modules. When configured, the HVAC economizer module automatically detects the dual sensor setup, allowing for differential enthalpy sensing between outdoor and return air streams. This precise monitoring is essential for meeting modern energy codes and maximizing the operational lifespan of the compressor by leveraging favorable ambient conditions. Whether you are performing a field upgrade or replacing a Johnson Controls sensor, this kit provides the high-accuracy data required for demanding commercial HVAC applications.

• Enhanced Energy Efficiency: Shifts cooling load to ambient air based on total heat content (enthalpy), reducing compressor runtime.
• Smart Equipment Integration: Native compatibility with York Smart Equipment controls for plug-and-play detection and automated configuration.
• Dual Sensory Input: Precisable measurement of both temperature and humidity for effective differential enthalpy control.
• Broad Compatibility: Engineered specifically for York, Johnson Controls, and Unitary Products Group 3-25 ton packaged rooftop units.
• Durable Construction: Built to withstand the harsh environments of rooftop outdoor air intakes.

How does this kit differ from a standard dry-bulb sensor?
Unlike a dry-bulb sensor that only measures temperature, the 2EC0402 measures humidity as well. This prevents the economizer from pulling in high-humidity outdoor air that would increase the latent cooling load on the system.

Is this kit compatible with older York Sunline units?
This kit is specifically designed for units featuring Smart Equipment controls (typically 3-25 tons). For older legacy units with Honeywell or Simplicity controls, verify the specific harness connections and mounting plate requirements before installation.

Do I need two kits for differential sensing?
The 2EC0402 is a dual enthalpy kit often containing the secondary sensor and harnesses needed to compare outdoor air with return air. Always verify existing factory-installed components to determine if additional sensors are required for your specific configuration.
