Honeywell C7400A2001 Enthalpy Sensor
The Honeywell C7400A2001 is a professional-grade solid state enthalpy sensor designed for integration with economizer logic modules to optimize outdoor air intake based on total heat content. This analog enthalpy sensor provides a precise 4-20mA output signal that increases as enthalpy levels decrease, allowing for seamless communication with W7212A, W7459, and W7215 controllers. Engineered with a durable, corrosion-resistant glass-fiber reinforced plastic housing, it effectively measures temperature and humidity across an operating range of -40?F to 150?F with 5% accuracy. For maximum energy efficiency, technicians often deploy two units?one for outdoor air and one for return air?to achieve differential enthalpy control. This sensor is functionally identical to the Honeywell C7400A2001/U and is essential for maintaining ASHRAE-compliant ventilation in commercial rooftop units.
Key Benefits:
- Enables free cooling by accurately determining the total heat (enthalpy) of ambient air.
- Directly compatible with Honeywell economizer systems including W7210, W7213, and W7460 series.
- Features 1/4" quick connect terminals for rapid job-site installation and wiring.
- Offers long-term stability and resistance to environmental contaminants like dust and dirt.
- Supports differential enthalpy sensing when paired with a second C7400 unit to maximize ROI on HVAC systems.
Common Questions:
What is the difference between the C7400A2001 and C7400A2001/U?
They are the same technical product; the "/U" suffix simply denotes the retail-packaged version ("Universal") while the base part number is used for wholesale and bulk distribution.
Can I use this sensor with the JADE W7220 Economizer?
No, the JADE system typically utilizes Sylk Bus digital communication. The C7400A2001 provides a 4-20mA analog signal and is built for legacy logic modules like the W7212 and W7459.
How do I wire this sensor for differential control?
You must install two sensors?one in the return air duct and one in the outdoor air intake?and wire them to the appropriate terminals on your Honeywell economizer logic module (such as the W7212) to compare air conditions for optimal dampening.
