Siemens Building Technology QAA22SS.FWSN Stat
The Siemens QAA22SS.FWSN is a high-precision room temperature sensor engineered for seamless integration into Building Automation Systems (BAS). This full-featured HMI unit provides technicians with a versatile selectable output signal (0-10V, 0-5V, or 4-20mA), making it compatible with a wide range of HVAC controllers and Terminal Equipment Controllers (TECs). Designed for accuracy, the sensor offers a measurement range of 32°F to 122°F with a tolerance of +/- 0.9°F. Its 55°F to 95°F setpoint adjustment and momentary occupancy override allow for localized climate control without compromising system energy efficiency. The unit’s patented housing features strategically placed ventilation slots that optimize airflow across the sensing element for a faster response time. For installation, the QAA22SS.FWSN supports hardwired terminal block connections and is sized for mounting on a standard 2" x 4" electrical box or directly to a flat wall surface using the included hardware.
Key Benefits
- Universal Compatibility: Field-selectable 0-10V, 0-5V, or 4-20mA analog outputs ensure this unit works with almost any analog input controller.
- Enhanced User Interface: Features a full HMI display for real-time room temperature monitoring and digital setpoint adjustment.
- Advanced Airflow Logic: Patented housing design utilizes ventilation slots to prevent stagnant air pockets, ensuring higher sensing accuracy.
- Flexible Power Requirements: Operates on 24 VAC (±20%) or 18-36 VDC, providing versatility for various onsite power configurations.
- Maintenance Ready: Includes a dedicated tool port for easy commissioning and troubleshooting when used with compatible Siemens diagnostic tools.
Common Questions
How do I switch between 0-10V and 4-20mA outputs?
Output selection is typically handled via internal DIP switches or jumpers on the PCB; always verify the configuration against the wiring diagram before powering the 24V circuit.
Can this sensor be used for humidity monitoring?
No, the QAA22SS.FWSN is a dedicated temperature sensor. For combined temperature and humidity, the QFA32 series is the standard industry alternative.
Is the setpoint range adjustable beyond 55/95°F?
The hardware is hard-coded for a 55°F to 95°F setpoint signal range to remain within typical HVAC comfort cooling and heating parameters.
