What to do if my DeDietrich INNOVENS PRO MCA 160 Boiler displays 'TFlow Open'?
If your DeDietrich Boiler displays 'TFlow Open', it indicates that the flow temperature sensor is open. Check the wiring and connectors for bad connections, ensure the sensor is correctly fitted, and replace the sensor if it is faulty.
What to do if the fan speed on my DeDietrich Boiler has exceeded normal operating range?
If your DeDietrich Boiler displays 'Fan speed has exceeded normal operating range', it indicates a fan fault. Check the wiring and connectors for bad connections. Also, check for excessive chimney draught if the fan operates when it should not be. If necessary, replace the fan.
What to do if my DeDietrich INNOVENS PRO MCA 160 displays 'Return Higher Flow'?
If your DeDietrich Boiler displays 'Return Higher Flow', it indicates that the flow and return are reversed. Check the wiring and connectors for bad connections. Also, check the circulation direction (pump, valves) and ensure the sensor is correctly fitted. Verify the Ohmic value of the sensor and replace the sensor if faulty.
What to do if my DeDietrich INNOVENS PRO MCA 160 displays 'False flame detected before burner start'?
If your DeDietrich Boiler displays 'False flame detected before burner start', it indicates a false flame signal. The burner may remain very hot. Check the ionisation/ignition electrode, and if no flame should be present but O 2 Ionisation current is measured. If necessary, replace the faulty gas valve or ignition transformer.
What to do if my DeDietrich Boiler displays 'Max Tflue Gas'?
If your DeDietrich Boiler shows 'Max Tflue Gas', it means the maximum flue gas temperature has been exceeded. Replace the sensor if it is faulty. Also, check the flue gas outlet system and the heat exchanger to ensure that the flue gas side is not clogged.
What to do if my DeDietrich INNOVENS PRO MCA 160 Boiler displays '5x Flame Loss Error'?
If your DeDietrich Boiler displays '5x Flame Loss Error', it means flame loss has occurred 5 times. You should purge the gas supply to remove air, check whether the gas tap is properly open, and check the gas supply pressure. Additionally, check the operation and setting of the gas valve unit, ensure that the air inlet and flue gas discharge flues are not blocked, and verify that there is no recirculation of flue gases.
What to do if my DeDietrich INNOVENS PRO MCA 160 Boiler displays 'Delta T Max 3'?
If your DeDietrich Boiler displays 'Delta T Max 3', it indicates that the maximum heat exchanger temperature increase has been exceeded. You should check the circulation (direction, pump, valves) for no flow or insufficient flow, check the water pressure, ensure the cleanliness of the heat exchanger, and verify the installation has been correctly vented to remove air. Also, check that the sensors are operating correctly and have been fitted properly.
What to do if my DeDietrich INNOVENS PRO MCA 160 displays 'Max THeat Ex'?
If your DeDietrich Boiler displays 'Max THeat Ex', it indicates that the maximum heat exchanger temperature has been exceeded. You should check the circulation (direction, pump, valves), water pressure, and ensure the sensors are operating correctly and properly fitted. Additionally, verify the cleanliness of the heat exchanger and that the installation has been correctly vented to remove air.
What to do if my DeDietrich Boiler displays 'Max Delta TH-TR'?
If your DeDietrich Boiler is showing 'Max Delta TH-TR', it means the maximum difference between the heat exchanger and return temperature has been exceeded. Check the circulation (direction, pump, valves) for no flow or insufficient flow. Also, check the water pressure, the cleanliness of the heat exchanger, and ensure the installation has been correctly vented to remove air. Finally, verify the sensors are operating correctly and properly fitted.
What to do if my DeDietrich INNOVENS PRO MCA 160 displays 'Max Delta TH-TF'?
If your DeDietrich Boiler is showing 'Max Delta TH-TF', it means the maximum difference between the heat exchanger and flow temperature has been exceeded. Check the circulation (direction, pump, valves) for no flow or insufficient flow. Also, check the water pressure, the cleanliness of the heat exchanger, and ensure the installation has been correctly vented to remove air. Finally, verify the sensors are operating correctly and properly fitted.
