Just hooked up my digi's and it did the work for me never really looked at a PT chart with vapor/liquid pressures.
makes me think back a few years ago, back to a chain of stores my old company used to service.
Each case used a case controller that used a pulsing metering device that based superheat off of coil inlet/outlet temperature difference.
Each store was R-404A and worked well.
Then they put in a 407C store...and it was oil fail central.
This actually proves a point I tried to make a few times and got slammed for it.... Glad you knew the manifold set was smarter than you were....
Not being condescending, just appreciating you know the difference.
GTIf a day goes by and you have learned nothing, I hope you got a lot of sleep.
