Marvair 70571 Enthalpy Sensor
For industrial HVAC efficiency, the Marvair 70571 Enthalpy Sensor is a critical component for managing economizer functions and indoor air quality. As a solid-state C7400A2001 equivalent, this sensor measures the total heat content—both sensible temperature and latent humidity—to determine when outdoor air is suitable for free cooling. Integrating this economizer enthalpy control into your Marvair wall-mount air conditioner or heat pump ensures the compressor remains locked out during optimal ambient conditions, significantly reducing energy consumption and mechanical wear. This HVAC enthalpy sensor is engineered for high-precision sensing in vertical packaged units and industrial refrigeration systems, facilitating accurate outdoor air sensing and differential enthalpy logic when paired with a second unit. Its rugged design ensures long-term reliability for technical professionals managing Marvair replacement parts in demanding environments. By monitoring the total heat of the return and outside air, the 70571 optimizes the changeover point for economizer air conditioning, maintaining tight climate control without unnecessary equipment cycling.
Key Benefits for Technicians:- Precise Energy Management: Accurately triggers economizer dampers based on total air heat content, maximizing free cooling hours.
- Universal Marvair Compatibility: Direct OEM replacement (MPN 70571) for various Marvair ComPac and GreenPac series units.
- Solid-State Reliability: Replaces Honeywell C7400A series sensors with durable, maintenance-free solid-state technology.
- Dual-Sensing Capability: Measures both sensible temperature and relative humidity to calculate true enthalpy for superior climate control.
- Streamlined Installation: Lightweight 0.24 lb design with standard mounting points for fast field replacement.
How do I test if the Marvair 70571 is functioning correctly?
Technicians can verify operation by measuring the milliamp output or using a component aerosol cooler to "trick" the sensor into a low enthalpy state, forcing the economizer to open the outdoor air dampers.
Can this sensor be used for differential enthalpy sensing?
Yes, for differential enthalpy control, two Marvair 70571 sensors must be installed—one for return air sensing and one for outdoor air sensing—to compare total heat levels for maximum efficiency.
What happens if the sensor fails?
A failed sensor typically defaults the economizer to the closed or minimum position, preventing free cooling and forcing the system into mechanical cooling, which increases energy costs.
