Siemens Building Technology QAA2280.FWSC Sensor
The Siemens Building Technology QAA2280.FWSC is a high-performance room temperature sensor designed for precise environmental control in commercial HVAC applications. This full-feature HMI unit is engineered specifically for Siemens Terminal Equipment Controllers (TEC), including BACnet TEC, ATEC, and PTEC models. It features a digital LCD display for real-time monitoring and a simplified RJ-11 connection that facilitates rapid, error-free wiring directly to the controller’s room unit port. With a standard operating range of 55°F to 95°F (13°C to 35°C), this sensor provides accurate feedback for space temperature management. Integrated setpoint adjustment and override buttons allow for local occupant control, while the bottom-facing tool port provides technicians with direct access for commissioning via a laptop or passkey tool without removing the cover. The sleek, low-profile housing is optimized with ventilation slots to ensure maximum airflow across the sensing element for increased thermal response speed.
Key Benefits:- Direct TEC Compatibility: Engineered specifically for seamless integration with Siemens TEC and BACnet PTEC controllers via RJ-11 connection.
- Integrated HMI Display: Provides clear room temperature and setpoint feedback, allowing for immediate status verification on-site.
- Efficient Commissioning: Built-in tool port enables field technicians to connect Siemens WCIS or configuration tools directly at the sensor.
- Occupant Control: Includes intuitive setpoint adjustment and an override button to manual trigger occupied sequences.
- High-Accuracy Sensing: Precise thermistor technology delivers consistent HVAC temperature control within tight tolerances for office and classroom environments.
Is the QAA2280.FWSC compatible with third-party controllers?
No, this specific model utilizes a digital communication protocol designed exclusively for Siemens Terminal Equipment Controllers. For universal 0-10V or resistive applications, a different series sensor should be selected.
How is the sensor powered?
The unit is powered using the TEC RJ-11 port. No external 24V power supply is required when connected to a compatible Siemens controller via the standard 6-wire cable.
Can I use a standard phone cable for the connection?
While the physical port is an RJ-11, it is recommended to use Siemens-approved 6-wire cables to ensure proper pin-to-pin mapping and signal integrity for digital communication.
