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.

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.

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.
F39
Outdoor
Temperature
Sensor Fault
Outdoor temperature sensor
might be defective.
1- Press reset button.
2- If the error is still present (or persists)
after reset, notify gas safe engineer.
F40
High Water
Pressure Fault
It occurs when water pressure
sensor detects a relatively high
water pressure (3,3 ±0,3 bar)
for your boiler.
1- Check water pressure in heater
installation of your boiler.
2- Tur off the boiler and restart it.
3- If the error is still present (or persists)
after reset, notify gas safe engineer.
