        • xEnClockButton = false

        • xEnToggle = false

      • The two parameters mentioned above must not be changed during online operation. Reason: The FB 'HVAC.Button1' does not detect parameter changes during online operation

  • FB 'EBM_SERIEN_84_112_150_200_V6_0' and 'EBM_SERIEN_84_112_150_200_V6_3':

    • Register D103: The default value was changed from 1 to 0
