Error cause
Way of error removing
No flame on the burner:
3 automatic re-ignition attempts are taken. Each attempt
is preceded by 15 sec. break for ventilation of the boiler.
After the failure of attempts follows: switching off the
boiler with blockade, displaying the symbol E
RESET
01
The boiler is in the process of gas ignition
tests and will return to normal operation.
No flame on the burner:
Turning off the boiler with blockade after unsuccessful
attempts of gas ignition. The reason of failure may be:
1.
Lack of gas.
2.
Erroneous connection to power source (phase
detection)
Check if the gas cocks are opened and if
the gas reaches the boiler.
Press reset button
To fix: - turn off power
- switch lines of power cable
The water temperature in the gas-water heat exchang-
er
exceeds 90ºC. The one-time thermal fuse was burned
off and the boiler was switched off with blockade.

Incorrect pressure in CH system.
if: P>2.8 bar - controller turns off the burner, the pump
operates for 180 secs,
if: P<0.5bar - controller turns off the burner, the pump
operates for 180 secs,
P <= 2.5 bar - return to the normal operation.
P >= 0.5 bar - return to the normal operation.
When the pressure in CH is higher than
2.8 bar some water should be drained from
installation. The pressure may be too high
if there has been too high initial pressure
in the system or if there occurred damage
in the compression vessel. If the pressure
in the CH system is below 0.5 bar you
should fill in the system with water and
check for leaks
Failure in the circuit of NTC temperature sensor (in DHW
system). The burner is turned off.
