    York YCAS0230EC40

    Hello everybody! How have all you been?
    I'm lookig for the p/n about the eprom that must be used in the YCAS0230EC40, when it is using R407C. I've been checking three of then that someone change the refrigerant but did not change the eprom and I like to correct them.
    Another doubts: There is a way (or configuration) to say to microboard what is the starter mode if "across the line" or "wye-delta"?
    Any comments will be appreciated!

    That is what is listed in the book the selection would be determined when the Chiller is commissioned for start up either for R22 or R407C.
    A mind is like a parachute. It doesn't work if it is not open.

    The best part of going to work is coming back home at the end of the day.

    Hard work spotlights the character of people: some turn up their sleeves, some turn up their noses, and some don't turn up at all.

    Digit # 11 would be as follows X = Across The Line
    Y = Wye Delta
    That would be from the Factory can't change in the field.
