Can your guys please explain me why the PSIO of Carrier 19XL5353304CR with R134A S/N 1994Jxxxxx chiller converts Evap Refrig Pressure 33.7 psig to 40 f Evap Refrig Temp? The sat. temp of R134A at 33.7 psig is 38.59 f?
The evap. pressure transducer has been calibrated at 0 psig and 250 psig per IOM.
Is it a problem with PSIO?
What is the guide vane travel limit for this model to set in SERVICE3 screen under EQUIPMENT SERVICE menu?
