    Hi Soulreaver18.
    Welcome to the forum.
    I have managed to find this advise!

    Invalid Serial Number Warning
    If the INVALID SERIAL NUMBER message appears,
    immediately contact YORK Product Technical Support.
    The appearance of this message may mean the chiller
    has lost important factory programmed information. The
    serial number can be entered using the Service Key.
    Additionally, when this appears, an Optimized IPLV
    chiller will only run in Standard IPLV control mode.
    Optimized IPLV cannot be enabled unless the serial
    number is programmed into the unit using the special
    password supplied by YORK Product Technical Support.
    Once the password is entered, a second password will be
    needed to activate the optimized IPLV control.
    This status message can be bypassed to view addi-
    tional messages under the STATUS key by pressing
    the STATUS key repeatedly to scroll through as many
    as three STATUS messages that could possibly be
    displayed at any time.

    It would appear that your software has become corrupted!
    Did you have a Power Cut / Spike or Something?

    You need to contact JCI / York, I am afraid.
    There are no quick fixes for this one!
    Good Luck Grizzly.
