Description
The AAON ASM01831 is an E-BUS duct-mount CO2 sensor engineered as a genuine OEM replacement component for compatible AAON HVAC equipment. Designed to integrate seamlessly with AAON’s E-BUS communication architecture, this sensor continuously monitors carbon dioxide concentrations in the supply or return airstream, providing the data needed for demand-controlled ventilation (DCV) strategies that optimize indoor air quality and energy efficiency.
Key Features
- Genuine AAON OEM replacement part (SKU: ASM01831)
- E-BUS communication interface for direct integration with compatible AAON rooftop units and air handlers
- Duct-mount design for accurate in-duct CO2 concentration measurement
- Supports demand-controlled ventilation (DCV) to optimize fresh air delivery and reduce energy waste
- Helps maintain healthy indoor air quality (IAQ) in commercial and industrial environments
- Plug-and-play compatibility with AAON E-BUS control systems — no additional signal converters required
Applications
- AAON rooftop units and air handling equipment equipped with E-BUS controls
- Commercial buildings, schools, offices, and other occupied spaces requiring IAQ monitoring
- Demand-controlled ventilation systems seeking accurate CO2 feedback
Why Choose an OEM AAON Sensor?
Using a genuine AAON replacement sensor ensures full compatibility with your unit’s E-BUS control network, preserving factory calibration protocols and system warranties. Third-party substitutes may not communicate correctly with AAON’s proprietary E-BUS architecture, potentially causing control faults or inaccurate readings. The ASM01831 is the correct, manufacturer-specified solution for maintaining peak system performance and indoor air quality compliance.
