This I know, my temperature indication quit working. I pulled the tank for another reason. I found the puck had come loose from that circle in the well. Cleaned every thing up glued it back down and temperature indication started working. About a year later it quit again. I pulled the tank again to prepare the well for a new unit and it was loose again. I would be glad to text some pictures. The old transducer is about an inch wide by about 4 inches long. I have no idea how that round puck worked thus my question. In fact I can find no connection between that puck and the old unit.
My old unit only has one multi pin connector with power cable and transducer cable going to that one multi pin connector.
