Siemens Building Technology QAA2235.EWSN Sensor
The Siemens QAA2235.EWSN is a precision room temperature sensor engineered for seamless integration into commercial Building Automation Systems (BAS). Utilizing a 100k Ohm thermistor active output, this unit provides highly stable and linear temperature feedback to HVAC controllers, ensuring tight deadband management and optimized energy efficiency. Designed specifically for indoor comfort monitoring, it operates across a standard range of 32°F to 122°F (0°C to 50°C). This model features a clean, no-display wall mount configuration, which prevents unauthorized setpoint tampering while maintaining a low-profile aesthetic in professional environments. Installation is streamlined via a robust terminal block interface, allowing for efficient wiring and field service. For technicians managing large-scale facility networks, the Siemens 100k Ohm sensor is a reliable choice for maintaining accurate environmental conditions in occupied zones without the complexity of local digital interfaces.
Key Benefits:
- High-impedance 100k Ohm thermistor provides accurate signal transmission with minimal self-heating errors.
- Optimized for Siemens building technology platforms and standard third-party commercial HVAC controllers.
- Robust terminal block connection ensures secure, long-term electrical contact and simplifies troubleshooting.
- Sleek, non-display housing design reduces architectural impact and eliminates potential points of failure or tampering.
- Reliable performance across a wide HVAC environmental monitoring range for standard office and commercial applications.
Common Questions:
- What is the primary signal output for the QAA2235.EWSN? This sensor utilizes a 100k Ohm thermistor output to communicate with BAS controllers.
- Can this sensor be used for outdoor temperature sensing? No, this unit is specifically designed for indoor wall-mounted applications within a controlled environment.
- Is manual calibration required during installation? These thermistors are factory-calibrated for high stability, though field-checking against a reference thermometer is standard practice for commissioning.
