Lochinvar & A.O. Smith 100173054 Inlet Sensor Els PW 29614 Replacing a legacy or failedThe Lochinvar & A. O. Smith 100173054 Inlet Sensor is a critical NTC thermistor engineered for precise temperature monitoring in high efficiency commercial water heaters and hydronic boilers. This sensor, which is cross compatible and functionally identical to WRE2145, monitors the incoming water temperature to provide real time data to the control module. This allows the system to modulate the firing rate accurately, maintaining a stable delta T
