The Maxitrol TS214BC is a specialized dual discharge air temperature sensor engineered for precise thermal monitoring in Selectra Series 14 modulating gas control systems. This OEM Maxitrol sensor features two distinct operating ranges: 120°F to 170°F and 160°F to 210°F. Designed to be used with a mixing tube, the TS214BC provides the critical feedback loop required for electronic gas flame modulation, ensuring stable discharge air temperatures in direct-fired make-up air units and industrial heating applications. By utilizing high-sensitivity thermistor technology, this sensor allows the Selectra amplifier to make instantaneous adjustments for consistent performance. For field technicians, verifying the temperature range compatibility between the sensor and the existing amplifier is essential for maintaining system calibration. This HVAC temperature sensor is a direct replacement part, vital for restoring the accuracy of modulating gas valves and preventing temperature hunting or system cycling issues in commercial HVACR environments. Key Benefits Precise Dual-Range Monitoring: Provides accurate sensing in 120-170°F and 160-210°F ranges for versatile system configuration. Instantaneous Response: Facilitates rapid adjustment of modulator-regulator valves, outperforming traditional mod motors. Seamless Integration: Specifically calibrated for use with Selectra Series 14 systems and standard Maxitrol mixing tubes. Durable Construction: Built for the demanding environments of industrial make-up air heating and direct-fired equipment. Common Questions Is the TS214BC compatible with all Selectra systems? It is specifically designed for Series 14 systems. Always match the temperature range on the sensor with the range specified on your Selectra amplifier. Can this sensor be installed without a mixing tube? This model is intended to be used with a mixing tube to ensure an accurate average air temperature reading across the duct. How do I troubleshoot a TS214BC sensor? Technicians should measure the resistance across the sensor leads and compare it to the Maxitrol resistance chart at a known temperature to verify calibration.
