Siemens Building Technology QAA2230.EWNN Sensor
The Siemens QAA2230.EWNN is a high-precision room temperature sensor designed for seamless integration into building automation systems. Utilizing a 10k Ohm Type 2 NTC thermistor, this sensor provides reliable resistance output signals to controllers, ensuring accurate environmental monitoring in commercial and institutional spaces. This specific model features a "blank front" without a logo or digital interface, making it ideal for clean architectural installations where a discreet profile is required. Built on a terminal block connection platform, it supports straightforward field wiring and maintains a stable operational range from 32°F to 122°F (0°C to 50°C).
For service technicians and contractors, the QAA2230.EWNN thermistor is a versatile solution for standard wall-mount applications. Its NEMA 1 rated enclosure is engineered with strategically placed ventilation slots to optimize airflow across the sensing element, reducing thermal lag and improving response times. As a passive temperature sensor, it eliminates the need for complex external power at the device level while remaining compatible with a vast array of HVAC controllers that support 10k Type 2 curves. Whether you are performing a retrofit or a new installation, this Siemens unit offers the durability and signal consistency required for demanding climate control logic.
Key Benefits for Technicians:- High Accuracy: Features a 10k Type 2 thermistor with a typical accuracy of +/-0.4°F for precise temperature tracking.
- Universal Compatibility: Standard resistance output works with Siemens Apogee, Desigo, and most third-party BAS controllers.
- Simplified Mounting: Designed for installation on standard 2" x 4" electrical boxes or direct drywall mounting with included hardware.
- Professional Aesthetic: The no logo, no display design prevents unauthorized tampering and maintains a neutral appearance.
- Secure Connections: Reliable terminal block interface ensures a solid mechanical and electrical bond for field wiring.
Is this sensor compatible with non-Siemens controllers?
Yes, as long as the controller is configured to read a 10k Ohm Type 2 NTC thermistor curve, this sensor will provide accurate data regardless of the brand of the building management system.
Does this unit require a separate power supply?
No, this is a passive resistance sensor. It functions by changing resistance based on temperature, which the controller interprets; it does not require an active voltage input to operate.
Can I install this in a high-humidity environment?
This unit is NEMA 1 rated and intended for indoor room applications. For high-humidity or wash-down areas, a sensor with a higher NEMA or IP rating should be used.
