One Place Monitor Panel not programmed right.

The One Place monitor panel in our 2015 Winnebago 36Y has had slightly incorrect readings on tank levels since we bought it new. Until now, I was writing it off to crappy sensors (there seems to be much grief discussed here about tank sensors). Taking a shower this morning on the last day of our outing left me standing in a smelly puddle in the shower pan with the One Place showing only 3/4 full for the grey tank. Another thing that had long irritated me was the grey 2 and black 2 that displayed while we only have one of each. I just assumed the panel was a 'universal' that would also be used on a rig with multiple tanks and the display was a result of that. Today I went searching and found a small manual for download at the Precision Circuits Inc. site that gave the instructions of how to program the panel. Apparently Winnebago did not (maybe on all units??) do the programming that is needed to correctly match the panel to the individual coach. It WILL work as is out of the box but not to the level of accuracy it is capable of. After holding the pump, tank, and battery button down together for 6 seconds to put it program mode, then pressing pump, then battery, returned the screen to just displaying the water pump status. Pressing electric water heater button, then LP water heater button enabled those two functions and pressing tank made it self program the 2 waste tanks correctly. Pressing battery exited programming. Now everything works like it should and the 2 extra tank displays are gone!
