58 Code: Code: Code: Code: Fault finding Description: Lack of water (only for pump equipped with SensorLogic) Corrective action: Fill-up the water circuit Description: Main heat exchanger frozen Corrective action: Carefully de-frost the exchanger Code: Description: Intervention of the high limit thermostat (TL) Code: Description: Modulating fan failure Corrective action: Check the fan’s wiring Description: Modulating fan failure Corrective action: Check the fan’s wiring Corrective action: Press the reset key on the control panel Description: Heating sensor failure Corrective action: Check the sensor’s efficiency and/or wiring Code: Description: Alteration of the operating parameters caused by EMC disturbances Corrective action: Restore the factory parameters Code: Description: Flame signal detected before the ignition cycle Corrective action: Disconnect the detection electrode’s wire from the control board; if the error code disappears replace the cable, otherwise replace the control board. Code: Description: Flame detected after burner OFF Code: Corrective action: Disconnect the gas valve’s wire from the control board; if the error code disappears replace the control board, otherwise replace the gas valve. Description: Internal failure Corrective action: Replace the control board 5.2 - REQUEST OF MAINTENANCE The boiler has an integrated system that, after 10.000 switching On or 2.000 hours of operation of the burner, provides to signal that the boiler needs maintenance. Such information is indicated on the display by the lighting of the code . The flashing of the code doesn’t inhibit the normal operation of the boiler. Service the appliance and subsequently reset the counter by selecting “Cr” from the parameters menù and introducing the relevant resetting code.
5.3 - DISPLAY OF ERROR CODES ON HEATING CONTROLLER E8 Code: Description: Air in the pump (only for pump with Sensor Logic E 41 Corrective action: Manually bleed the air from the circuit Code: Description: DHW sensor failure (SS) (only if the boiler is combined with an external D.H.W. tank) E 13 E 14 Code: E 32 E 2 E 15 E 42 18 24 12 6 Corrective action: Check the sensor’s efficiency and/or its wiring Code: Description: Insufficient gas pressure Corrective action: Check the pressure, if the pressure is correct control the gas switch and/or its wiring. Code: Description: Difference between the temperature of the CH sensor (SR) and the temperature of the heating return sensor (SRR) > 35°C. Code: Description: Mains supply < 190 Vac Corrective action: Check that the mains supply is < 190Vac. If the mains supply is correct replace the control board. Corrective action: Examine the system. Description: Jammed pump (only for pump with SensorLogic) Corrective action: After removal of the central plug of the pump body turn with a screw driver the pump rotor and replace the plug. Fault finding In case of fault, on the display of the regulator a blinking triangle with its error code will appear Here below you will find the E8 error codes, the relevant meaning and corrective actions. For the error codes related to the heating system, make reference to the paragraph “Fault finding” of the “User Instruction manual” supplied with the E8.<strong>50</strong>64 heating controller. Codice: Description: Failure on the pump wiring (only for pump with SensorLogic) E 43 Code: Code: E 40 Code: E 6 Code: E 5 Code: E 4 Corrective action: Verify the wiring Description: Failure of the heating return sensor (SRR) Corrective action: Check the efficiency of the sensor and/or its wiring Description: Bad water circulation Corrective action: Examine the system Description: Water temperature too high detected by the CH sensor (SR) (>95°C) Corrective action: Check adequate flow of water through boiler Description: Loss of flame signal during boiler operation Corrective action: Press the reset button on the control panel Description: No flame detected during the ignition phase Corrective action: Press the reset button on the control panel 59
