E44
Gas valve on error
The gas valve may
be defective.
1- Set the P50 parameter to “2”.
2- If the problem persists, replace the gas valve.
3- Replace the motherboard as last resort.
E64
Hardware error 1
Specific hardware
error
1- Turn the device off and on.
2- If the problem persists, replace the mainboard.
E65
Hardware error 2
Specific hardware
error
1- Turn the device off and on.
2- Check the gas valve connections.
3- If the problem persists, replace the mainboard.
E80
Swap test error
Return water
temperature sensor
temperature higher
than supply water
sensor temperature
1- Ensure that the connections of the CH supply and return water temperature sensors are correct.
Reset the device after securing the connections.
2- If the problem persists, replace the temperature sensors.
3- Check the cable connections of the pump and ensure the cables are not damaged. If there is a problem,
replace the pump cables.
4- Ensure that the pump is working properly. If there is a problem, replace the pump.
5- If the problem persists, replace the mainboard.
E82
Flame loss error (more
than 12 consecutive
flame losses)
Flame detection
problem
1- Check the gas settings. If the setting are not correct, adjust the gas settings according to the gas setting
table given in the manual.
2- Check the flue connections and installation as indicated in the manual. If there is a problem, remove
the flues and check for obstructions in the air intake and gas discharge sections as well as the
compatibility of the ports and seals.
3- Measure CO2 emissions in the clean air section from the boiler flue elbow. CO2 emission value
should be less than 0.1%.
4- Check the fan-venturi-silencer assembly.
5- Check if the gas pressure at the gas valve inlet is above 12 mbar.
6- Ensure that the connection of the ignition electrode cable (both on the mainboard and on the main heat
exchanger) is done correctly and that it sits properly. If there is a problem, make sure it is properly installed
and locked. Then reset the device.
7- If the problem persists, remove the ignition electrode and check for oxidation. If there is oxidation,
clean the electrode and place it back and then reset the device.
8- Check the distance of the ignition and ionization electrodes. If there is a problem, adjust it according to the
measurements given in the manual. Then reset the device.
9- Turn off the boiler and check for a resistance of 110-120 ohm between the ends of the gas valve. If the
resistance value is not within this range, replace the gas valve.
10- Remove the gas valve connector and turn on the boiler's electrical connection. Ensure that there is a voltage
of 23-25 V between the ends of the connector from the mainboard during ignition. If it is not in this range,
replace the mainboard.
11- Check CO2 values and stability. If there is a problem, replace the gas valve.
E83
Exhaust gas high
temperature warning
(F07 error twice within
the last month)
Main Heat Exchanger
problem
1- You can refer to the explanations given for the F07 error.
E98
Hardware error 3
Hardware-specific error
1- There may be a problem with the mains frequency. Turn off and on the electrical connection of the device.
2- Check the error history for error F36. If you see this error, refer to the explanation for the F36 error.
3- If there is no problem with the mains voltage and frequency, replace the mainboard.
