Siemens QFA2020 Room Temperature Sensor 0-10V Active Output

QFA2020

The Siemens QFA2020 wall-mounted room temperature sensor is extensively deployed in commercial office complexes, educational institutions, healthcare facilities, and residential buildings. It functions as the primary space-temperature feedback device driving supply air dampers, VAV terminal units, fan coil units (FCU), and radiator zone valves. By providing exact, real-time room temperature data to Desigo CC or third-party BMS controllers, this Symaro sensor ensures optimal occupant thermal comfort and high HVAC energy efficiency.

Key Features & Technical Specifications：

• 0...10 V DC Active Output: Converts ambient temperature measurements into a standard linear 0...10 V DC analog signal for DDC controllers.

• Selectable Temperature Ranges: Default operating range of 0...50 °C with internal jumper selection for 0...35 °C or -35...+35 °C ranges.

• High-Precision Sensing Element: Integrated Pt1000/thin-film sensor element ensuring fast thermal response and long-term drift-free accuracy.

• Architectural Wall-Mount Housing: Elegant, compact white housing designed to blend seamlessly into modern office and commercial interiors.

• Optimized Ventilation Slots: Engineered casing airflow channels allow natural convection for accurate ambient temperature readings.

• Flexible Operating Voltage: Powered by standard AC 24 V (+/-20%) or DC 13.5...35 V supply lines for convenient panel wiring.

• Easy Terminal Installation: Features accessible plug-in/screw terminal blocks for fast field wiring and quick commissioning.
