Siemens Building Technology QAA22SS.EWNN Sensor
For building automation contractors requiring a tamper-proof and flexible environmental monitoring solution, the Siemens QAA22SS.EWNN stands as a professional-grade room temperature sensor designed for seamless integration. This "Sensing Only" variant features a blank front with no logo, making it the ideal choice for schools, high-traffic commercial spaces, or public corridors where preventing unauthorized setpoint adjustments is mission-critical. Leveraging the proven QAA2200 series architecture, this unit provides selectable analog outputs including 0-10Vdc and 4-20mA, ensuring out-of-the-box compatibility with most HVAC BAS controllers, including Siemens APOGEE and TALON systems. The low-profile wall-mount housing is engineered with strategically placed ventilation slots that optimize airflow across the sensing element, drastically reducing thermal lag for high-accuracy performance. Installation is streamlined via the standard 2x4 electrical box mounting pattern or direct drywall attachment, utilizing a robust terminal block for reliable field wiring. Operating within a standard 32 to 122 degree Fahrenheit range, this active analog sensor delivers the stability and precision professionals expect from Siemens Building Technology.
Key Benefits- Selectable Output Signals: Easily toggle between 0-10Vdc and 4-20mA signal types to match your controller’s input requirements without swapping hardware.
- Tamper-Proof Design: The no display and blank front configuration eliminates occupant interference and localized setpoint tampering.
- Enhanced Thermal Response: Patented housing design utilizes airflow optimization for faster detection of temperature shifts compared to standard flat-face sensors.
- Universal Mounting: Designed for rapid deployment with hardware included for 2x4 conduit boxes or flat surface/drywall mounting.
- Clean Aesthetics: Neutral white housing and no logo branding provide an inconspicuous, professional appearance that blends into any architectural environment.
Can I use this sensor with a 24Vac power supply?
Yes, the Siemens QAA22SS.EWNN is versatile, supporting an input voltage of 18 to 36Vdc or 24Vac ± 20%, allowing for standard field power configurations.
Does this unit require a separate mounting plate?
No, the base plate is designed to mount directly to a standard 2” x 4” US-style electrical box or directly to drywall with the included screws and anchors.
How do I switch between the 0-10V and 4-20mA signals?
The output signal is field-selectable via internal jumpers or dip switches on the PCB, allowing you to configure the room temperature transmitter for your specific BAS architecture during commissioning.
