    Carel PCO maintenance passwords



    Hi,

    I have some units under my maintenance contract with Carel PCO controller witch are experiencing maintenance alarms.
    Since these are abandoned by original installer (they gone out of businesses), I am unable to find or acquire original documentation.
    Unit in question are from Thermocold and Emicon.
    I would appreciate if anyone know what are maintenance passwords of those manufacturers, since original Carel maintenance password is not functioning there.


    Now, when I am officialy citizen off EU, I am looking for decent job! For any job offer please check my profile!

    Re: Carel PCO maintenance passwords

    Is it possible to order Carel EEPROM chip with software unlocked, like in Carel PCO available at stores, and only change parameters according to application ( i have no problem to parameter it myself)?
    I have two fully functioning PCO boards but with locked software. If I could buy only EEPOM chip and make changes in parameters it would be much cheaper for customer to go that way!

    Re: Carel PCO maintenance passwords

    Yes, it is tried 1000 and 0123 and 1234!

    Also, unit in question have 2 PCO boards. One is master and second one is slave.

    When we enter 1234 password on the screen appears question something like second (level?) password!
    It appears that 1234 is OK for first level or something like that, but another password is required for 2nd level.
    We need to reset compressor maintenance alarm.

    Re: Carel PCO maintenance passwords

    If I remember right there are three different passwords user,maintenance and manufacturer, your best bet is try and contact emicon as it is there software passwords and not carels

    All Carel PCo passwords which I met was between 0100 and 0120. Such as 0100, 0105, 0110, 0113 and 0118

    Re: Carel PCO maintenance passwords

    Emicon case is solved by replacing PCO board with another one from similar Emicon, but non functioning (mechanically) unit. I still don't know passwords for Emicon. Termocold case is solved by entering one of passwords listed here on thread, but i cannot remember which one!

    It must be related to my age!

    Anyhow, thanks to all contributors!
