Siemens Building Technology QFA3280.FWSC Sensor
The Siemens Building Technology QFA3280.FWSC Room RH Sensor is a high-precision digital field device engineered specifically for integration with Siemens Terminal Equipment Controllers (TEC). This room temperature and humidity sensor provides a dual-function sensing solution, delivering a 0-100% RH measurement range with ±2% accuracy and integrated temperature (P1) sensing. By utilizing a digital signal over a standard RJ-11 connection, this unit eliminates the signal degradation common in traditional analog circuits, ensuring the BACnet TEC controller receives stable, accurate environmental data for precise VAV or terminal unit control.
Designed for professional HVACR environments, the QFA3280.FWSC features a high-visibility LCD display for real-time monitoring of local conditions. The interface allows for direct setpoint adjustment and manual override functionality, providing occupants with controlled flexibility while maintaining system efficiency. An accessible tool port at the base of the housing enables technicians to connect a laptop or local HMI for commissioning and configuration without removing the cover. This full-feature HMI room unit is ideal for critical environments such as data centers, labs, and commercial offices where humidity precision is non-negotiable.
Key Benefits- Seamless TEC Integration: Optimized for plug-and-play installation with Siemens TEC platforms using 11-pin or 6-pin RJ-11 cabling.
- Field Commissioning Efficiency: The 1/8" tool port provides immediate access for HVAC configuration tools and local diagnostics.
- Enhanced Environmental Control: Dual-sensing allows the controller to adjust for both latent and sensible heat loads simultaneously.
- Occupant Interface: Features setpoint adjustment and override buttons to reduce service calls for minor temperature shifts.
- Robust Digital Communication: Digital P1 signal architecture minimizes electromagnetic interference (EMI) issues in dense ceiling plenums.
Is the QFA3280.FWSC compatible with non-Siemens controllers?
No, this specific digital room sensor is designed exclusively for use with Siemens Terminal Equipment Controllers (TEC) and communicates via a proprietary P1 digital signal.
What wiring is required for this room unit?
The unit typically uses a pre-terminated RJ-11 cable. It is essential to ensure the cable is crimped correctly to avoid "No Sensor" or "No TEC" error codes on the display.
Can the temperature display be switched between Fahrenheit and Celsius?
Yes, the display units are configurable. This is typically handled through a combination of jumper settings on the PCB and controller-level configuration during commissioning.
