Fault finding5.2 - DISPLAY OF ERROR CODES ON HEATING CONTROLLER E8Cod:Mining:24E30Alteration of the operating parameterscaused by EMC disturbances18126E32Mains supply voltage < 190 VacIn case of fault, on the display of the regulator a blinking trianglewith its error code will appearHere below you will find the E8 error codes, the relevantmeaning and corrective actions.Cod:E01E02E04E05E06E08Mining:Intervention of the high limit thermostat (TL)Insufficient gas pressureNo flame detected during the ignition phaseLost of the flame signal during the operationToo high water temperature detected by theheating sensor (SR) (> 95°C)Lack of waterE69E70E71E72E75E76E78E80E81E8: F5 – Flow temperature sensor heatingcircuit 2E8: F11 – Flow temperature sensor heatingcircuit 1E8: F1 – Lower storage temperature sensor(Buffer)E8: F3 – Higher storage temperaturesensor (Buffer)E8: F9 – Outer temperature sensor (AF)E8: F6 – DHW storage temperature sensor(SPF)E8: F8 – Boiler temperature sensor (KF)E8: F2 – Room temperature sensor heatingcircuit 1E8: EEPROM fault.
