The Maxitrol TS114C is a high-precision discharge air temperature sensor engineered specifically for technical integration within Maxitrol Selectra Series 14 modulation systems. This thermistor-based component is housed in a robust assembly designed for installation inside a mixing tube, where it provides instantaneous resistance feedback to the system's electronic amplifier. By monitoring discharge air temperature in the specific 160-210 degrees F range, the TS114C allows for the seamless, continual adjustment of gas-fired temperatures, serving as a technically superior alternative to traditional mod motors and butterfly valves. It is a critical component for direct-fired make-up air units requiring stable thermal regulation and rapid response to load changes. For a successful field installation, technicians must ensure that the Maxitrol TS114C is paired with a matching TD114 temperature selector to maintain linear calibration across the circuit. The sensor's 10,000-ohm nominal resistance at 77°F provides the base signal for the Selectra modulation loop, ensuring that your gas-fired equipment operates with high precision and avoids the thermal cycling associated with less sensitive controls. Key Benefits for Contractors: Precision Thermal Monitoring: Tailored for high-temperature make-up air heating applications with a calibrated 160°F to 210°F sensing range. Electronic Modulation Integration: Designed to work natively with the Maxitrol Series 14 amplifier for instantaneous gas flow adjustments. Enhanced System Stability: Eliminates the "hunting" and "droop" common in mechanical valve assemblies by providing rapid thermistor feedback. Durable Mixing Tube Design: Built to withstand high-velocity discharge air streams while protecting the internal 10k ohm thermistor element. Common Questions: What happens if my TS114C resistance is out of spec? If the sensor fails to produce the correct resistance-to-temperature ratio (roughly 10k ohms at 77°F), the amplifier may lock the system into continuous high or low fire. Always verify terminal connections 3 and 4 during troubleshooting. Can I use a TS114C with any Selectra system? No, the "C" suffix denotes the 160-210°F range. It must be matched with the corresponding TD114C or AD1014-1116 selector components to ensure the discharge air temperature sensor signal is accurately interpreted by the control logic. Where should the sensor be located for the best results? The TS114C should be installed in a location where it can sense an average representative temperature within the discharge stream, typically inside a mixing tube assembly to prevent erratic air patterns from affecting signal stability.
