The Aaon ASM01814 is a precision space temperature sensor engineered for integration with Aaon rooftop units and split systems. Functioning as a direct replacement for the legacy OE213-02 sensor, this device provides accurate ambient temperature monitoring to ensure consistent environmental control. The unit features an integrated override button, allowing technicians and facility managers to trigger temporary occupied setpoints manually. Designed for specialized HVAC applications, it utilizes thermistor-based sensing technology to communicate reliable thermal data to the Aaon VCM controller or building automation system. The low-profile wall-mount housing is built for durability in commercial environments, facilitating straightforward installation on standard junction boxes. For contractors servicing older equipment, this Aaon OEM part ensures full compatibility with existing wiring configurations and communication protocols, maintaining the high performance and efficiency standards expected from factory-certified components. Key Benefits Direct replacement for the obsolete OE213-02 model, ensuring seamless retrofitting without field modifications. Integrated manual override functionality provides users with immediate control over thermostat setpoints. High-accuracy resistance temperature detector (RTD) technology minimizes sensor drift and operational errors. Engineered specifically for Aaon environmental control systems, guaranteeing signal integrity and terminal compatibility. Robust commercial-grade housing protects internal circuitry while maintaining a professional aesthetic. Common Questions Is the ASM01814 compatible with non-Aaon control boards? This sensor is designed to communicate specifically with Aaon's proprietary control infrastructure. Using it with third-party controllers may result in inaccurate resistance readings or communication failures. Will this sensor replace my existing OE213-02 without rewiring? Yes, the ASM01814 serves as the manufacturer-designated direct replacement, engineered to match the pin-out and resistance curve of the original OE213-02. How does the override feature function during unoccupied hours? Pressing the override button sends a temporary signal to the HVAC controller to switch the unit from unoccupied to occupied mode for a pre-programmed duration set within the main controller parameters.
