Siemens Building Technology 540-680CA Sensor
The Siemens 540-680CA Sensor is a precision 10k Ohm NTC thermistor designed for seamless integration with Siemens Apogee systems and Terminal Equipment Controllers (TEC). This Series 1000 room unit features a flush-mounted occupancy override button and a high-accuracy setpoint adjustment slide, allowing for localized control without compromising system-level oversight. The Celsius temperature display provides real-time feedback for occupants, while the desert beige housing ensures a professional, low-profile appearance in commercial environments. Engineered with a styled ventilation ring, the unit optimizes airflow across the sensing element for a rapid measurement response and stable environmental regulation. This DDC room controller component is essential for maintaining zone equilibrium in complex HVAC building automation layouts. By utilizing standard RJ-11 jack connectivity, field technicians can ensure a secure, low-voltage interface with existing Siemens building technology infrastructure, effectively reducing commissioning time during site retrofits or upgrades.
Key Benefits- Precise Monitoring: Utilizes a high-stability 10k Ohm NTC Type II thermistor for accurate environmental sensing.
- Local Control: Integrated setpoint slider and override button provide immediate occupant adjustments for enhanced comfort levels.
- System Compatibility: Specifically engineered for use with Siemens Terminal Equipment Controllers and legacy Apogee trunk configurations.
- Optimized Airflow: Specialized cover design ensures fast response times to temperature fluctuations by increasing convective air movement.
- Easy Installation: Features a standard RJ-11 termination for simplified wiring to the RTS port on the controller.
Is the 540-680CA compatible with any brand of HVAC controller?
No, this specific Series 1000 sensor is designed for Siemens industrial systems, particularly Terminal Equipment Controllers (TEC). It uses a 10k Ohm NTC element with specific signal scaling for those devices.
Can I switch the display from Celsius to Fahrenheit?
The 540-680CA is factory-calibrated for a Celsius display. For Fahrenheit equivalents, the 540-680FA model is typically required, as the scale is fixed on these specific Series 1000 units.
What is the maximum wire run for this sensor?
The recommended maximum length for standard six-conductor room sensor cables is 100 feet (30.5 meters) to maintain signal integrity without excessive resistance.
