EWC Controls SAS Sensor
The EWC Controls SAS Sensor is a precision duct mounted supply air sensor engineered for high-accuracy temperature monitoring within residential and commercial HVAC zoning systems. This thermistor-based sensor is the direct replacement for ZPS components, providing seamless integration with legacy EWC Ultra-Zone legacy boards and modern NCM300, BMPlus, and 3000 series controllers. Designed for discharge air temperature monitoring, the SAS provides real-time data to the zone panel, enabling critical high/low limit protection to prevent evaporator coil freeze-ups or heat exchanger overheating. The probe's physical profile ensures minimal airflow disruption while maintaining thermal conductivity for rapid response times. For technicians performing retrofits or repairs, utilizing the EWC SAS sensor ensures system logic remains calibrated to factory specifications, maintaining optimal short-cycle protection and equipment longevity in multi-zone configurations.
Key Benefits
- Direct Compatibility: Engineered as the official successor to the EWC ZPS sensor, ensuring plug-and-play installation without recalibration.
- Enhanced System Protection: Delivers precise supply air temperature sensing to trigger safety cut-outs, protecting the compressor and furnace.
- Industrial Build Quality: Features a durable probe design for consistent performance in high-velocity duct environments.
- Accurate Thermistor Readings: Provides a tight resistance tolerance for reliable HVAC zone control sensor feedback.
- Simplified Wiring: Standard two-wire termination facilitates quick integration into existing EWC Ultra-Zone systems.
Common Questions
Can the SAS sensor be used in place of an older ZPS sensor?
Yes, the SAS is the functional and mechanical direct replacement for the discontinued ZPS model and is fully compatible with existing EWC control panels.
Where should the sensor be installed for the most accurate readings?
For optimal performance, the probe should be mounted in the supply air plenum, approximately 18 to 24 inches downstream of the heat exchanger or cooling coil, ensuring it is not in a dead air space.
What happens if the SAS sensor fails or is disconnected?
Most EWC panels will default to a bypass or safety mode, often indicated by specific LED patterns, to prevent equipment damage until a valid discharge air sensor signal is restored.
