    Hello Suleyman,

    Providing you are using a thermocouple range capable of increase to this value please use the following method.

    Enter Full level.

    Page to SP List.
    Scroll to SP H.
    Increase the Setpoint high limit from 850.

    If this does not work.
    Enter Config Level.
    Page to PU.
    Scroll to rnG.H
    Increase the value to 1000 or beyond.

    Exit from Config and adjust the SP High limit described above.

    If all fails please indicate what sensor you are using.
