| E12 | EEPROM Check fail | The electronic card may be failed |
1- Press reset button. 2- If the error is still present (or persists) after reset, notify gas safe engineer. |
| E15 | Measurement Deviation Fault of Temperature Sensors | Temperature sensors might be defective. |
1- Press reset button. 2- If the error is still present (or persists) after reset, notify gas safe engineer. |
| E16 | Error on Temperature Sensor for CH Supply Water | No temperature is detected by temperature sensor for CH supply. |
1- Press reset button. 2- If the error is still present (or persists) after reset, notify gas safe engineer |
| E17 | Error on Temperature Sensor for CH Return Water | No temperature is detected by temperature sensor for CH return. |
1- Press reset button. 2- If the error is still present (or persists) after reset, notify gas safe engineer. |
| E18 | Temperature Sensor Error | The temperature change on the temperature sensor is too high (> 30 ͦC) |
1- Press reset button. 2- If the error is still present (or persists) after reset, notify gas safe engineer. |
| E21 | Analog to Digital Converter Failure | The electronic card may be failed. |
1-Press reset button. 2-If the error is still present (or persists) after reset, notify gas safe engineer. |
| E33 | Error on Temperature Sensor for CH Return Water |
The return water temperature sensor is in short or open circuit state. |
1- If the error is still present (or persists) after reset, notify authorized service. 2- If the error is still present (or persists) after reset, notify gas safe engineer |
| E35 |
Error on Temperature Sensor for CH Supply Water |
The CH supply temperature sensor is in short or open circuit state. |
1- Press reset button. 2- If the error is still present (or persists) after reset, notify gas safe engineer. |
| E80 | Temperature Difference Error between CH Return Water Temperature and CH Supply Water Temperature Sensor |
Temperature detected by temperature sensor for CH return is higher than temperature detected by temperature sensor for CH supply sensor |
1- Press reset button. 2- If the error is still present (or persists) after reset, notify gas safe engineer. |
| E82 | Flame Failure (more than 3 flame loss in 4 minutes) |
Flame detection problem |
1- Press reset button. 2- If the error is still present (or persists) after reset, notify gas safe engineer. |
| F07 | Over Temperature Error for Flue Gas | It occurs when the temperature of the flue gas exceeds 95 °C. | 1-Notify gas safe engineer. |
| F13 | Repeated Reset Fault | Pressing of Reset button more than 5 times in an hour | 1- Notify gas safe engineer. |
| F34 | Low Supply Voltage | It occurs when the supply voltage falls below 170V. | 1- Notify gas safe engineer. |
| F37 | Low Water Pressure Fault | It occurs when water pressure sensor detects a relatively low water pressure (0.4 bar) for your boiler. |
1- Check water pressure in heater installation of your boiler. 2- Fill the system with water until the pressure reaches 1.5-2 bar (the boiler will eliminate error when the pressure is over 0,8 bar). 3-Check your valves and installation against leaks. 4- If the problem is still present (or persists), notify gas safe engineer. |
