Communication was deactivated. The error message won't disappear before the temperature has dropped below the critical value. The digitalSTROM Meter should be switched off to cool down and switched on again later. The connected load should be checked. Check the digitalSTROM Meter assembly if the error recurs (see chapter 3.3, step 2).
Hardware error
