Monthly values The processor unit stores the meter readings for energy, volume, the tariff register, missing time, and flow rate measuring time as well as the monthly maxima for flow rate, power, temperature differential, temperature heat and cold side with their date stamp for up to 60 months on the set day of each month.NOTICECentral European Time (CET) is the default time. Storage is performed at the appropriate times if daylight saving time is activated. Previous year’s values and monthly values can also be read out via the optical and the 20- mA interface.Error messages The meter continuously performs self-diagnostics, allowing it to detect and display a number of mounting or device errors.Error codeErrorNotes on serviceFL nEGWrong direction of flowCheck flow or installation direction; correct if necessaryIf necessary, alternating with:DIFF nEGNegative temperature differentialCheck place of installation of sensors; replace as requiredIf necessary, alternating with:F0
