Siemens Building Technology QAA2212.FWSN Sensor
The Siemens QAA2212.FWSN is a precision wall-mount room units designed for high-accuracy climate monitoring in commercial building automation systems. Built with a 1k Ohm Platinum RTD (385 alpha) sensing element, this unit provides a highly stable resistance output signal that minimizes drift over time compared to thermistor-based sensors. This room temperature sensor features a built-in LCD display (Full HMI) for real-time local feedback and an override button to allow occupants to trigger momentary contact for after-hours operation. With a measuring range of 32 to 122 degrees Fahrenheit (0 to 50 degrees Celsius), it is ideal for office, classroom, and retail environments. The terminal block connection ensures a secure landing for field wiring, while the low-profile enclosure includes strategic ventilation slots to maximize airflow across the Pt RTD element, ensuring a fast response to thermal changes. This unit is compatible with most HVAC controllers that accept standard 1k Ohm platinum signals.
Key Benefits:- High-Accuracy Sensing: Utilizing a 1k Ohm Platinum RTD (385 alpha) ensures precise temperature readings with minimal long-term signal degradation.
- Integrated HMI & Override: The digital display provides immediate local temperature visibility, while the override functionality allows for easy manual setpoint adjustments or bypass modes.
- Optimized Airflow: The patented housing design features ventilation slots specifically placed to enhance sensor response time and maintain accuracy.
- Easy Installation: Features a standard terminal block and is designed to mount directly onto 2x4 electrical boxes or drywall.
- What systems are compatible with the 1k Ohm Pt RTD output? The Siemens QAA2212.FWSN is designed for compatibility with any HVAC controller capable of reading a 1k Ohm Platinum 385 coefficient signal, including most Siemens TALON and Desigo systems.
- How do I handle the override signal wiring? The override function typically uses a momentary dry contact. Ensure your controller's universal input is configured correctly to recognize this pulse for occupancy overrides.
- Can the display be customized? This Full HMI unit provides local temperature feedback; however, setpoint limits and display configurations are typically managed through the field controller or the unit's local interface guide.
