    Confused YS EVAP TRANS OR PROBE ERROR

    Hello friends
    I help a translator my English is not good
    I have YORK YS units which we cooled water to 26ºF I have an EVAP failure TRANS OR PROBE ERROR
    the from 160.47-O1.1 (197) the eprom was changed to avoid this failure but when operating 5 minutes for per condenser flow switch
    With the previous eprom I have no problems with that failure
    Does the input on the I / O card change the switch signal?
    The card is a 031-01065-000 eprom part 031-01102-002

    regards

    The difference between your Leaving Chilled Water Temperature and your Saturated Evaporator Temperature is greater than 25F. Check your sensors for accuracy.
    Don't step on my favorite part of the Constitution just to point out your favorite part.

    Political Correctness is forced on you because you have forgotten decency.

    Technically speaking, they are all heat pumps.

    Hello JayGuy
    The sensors are fine, as well as the transducers The return of water is at 32ºF Sometimes the process increases up to 44ºF that's why it opens the differential. In a York manual it says that changing the EPROM disables this fault and changes it but afterwards of 5 min fails by flow switch
    with the previous eprom does not fail by flow

    Regards
