How do you calibrate a level sensor for a York, YCIV chiller? It's a 2011 chiller. I hear there is a button on it for calibration, but I don't see what to do. When the chiller is in the off mode, the flash tank level is at the top of the sight glass. The control board screen shows 15%. That matches the 1.5 vdc signal from the sensor to the main board so I am relatively sure the board is reading correctly, but the tank looks like more than 15%.
I know the chiller wants to maintain 35% when running. Seems like if I was reading low, the tank could over fill and wipe the compressor out through the economizer. Personally, if I were designing something so critical, I would put two sensors and alarm if they don't match.
