Lochinvar & A.O. Smith 100208559 Sensor 323080-701 this specific plate is optimized

this specific plate is optimized for the GV90+ cast iron condensing boiler architecture and is not interchangeable with standard GV or Ultra heat exchanger components

Contractor-Focused Setup: Direct-mount compatibility eliminates the need for complex linkage kits on standard ESBE valves

provided the system operates within its 0 to 25 psi control range

this spring provides the necessary linear feedback for stable medium-pressure steam or water flow regulation

always ensure the blower speed taps and jumpers are set to match the specific CFM requirements of the furnace being serviced to prevent premature heat exchanger fatigue

Lochinvar & A.O. Smith 100208559 Sensor 323080-701 this specific plate is optimizedThe Lochinvar & A. O. Smith 100208559 Dual Immersion Sensor is a critical OEM replacement component designed for precision temperature monitoring in high efficiency hydronic systems. This dual immersion sensor outlet assembly, also identified by part number TST20017K, utilizes a dual element thermistor to provide the control board with real time data on supply water temperatures.
