Weil McLain 383-500-602 Temp Sensor Specifically designed as a robustThe Weil McLain 383 500 602 is a critical return supply temperature sensor kit engineered for precise thermal monitoring within Weil McLain Ultra and SlimFit series boilers. This 12 Kohm NTC thermistor assembly provides real time data to the control board, allowing for accurate modulation and preventing short cycling. As a dedicated boiler replacement part, it ensures the system maintains the delta T required for high efficiency condensing operation.
