Case 1: Within 5 sec flame, then flame failure.
The flame is not detected. Check the ignition cable and electrode. (cable resistance 1k
•
Ohm).
The electrical earth of the heater is poor,
•
The print board is defective.
•
Case 2:
There is not enough gas pressure.
•
The mixture of gas/air is poor, adjust the gas valve
•
The gas valve does not open, check during ignition for 230V on the valve.
•
Check whether the ignition electrode sparks, replace cable, electrode
•
Case 3: Heat exchanger too hot
Check whether the system fan blows enough air.
•
Check the setting of the gas valve, the heater may me overloaded.
•
Case 4: Temperature sensor on heat exchanger error.
The sensor has internally 2 sensors. These differ too much. Measure the resistance
•
from each sensor, the resistance should be 20K at 25° en 25K at 20° . If the measured
values differ too much, replace sensor.
L-25 is heat exchanger sensor, L-26 is flue sensor
•
Case 5: Too many flame failures while burning
The setting of the gas valve is not ok, adjust the gas valve
•
The flue outlet is blocked
•
Case 6: The premix does not run
Premix fan is Blocked or the wiring is bad
•
Premix fan is defective
•
Case 7: The pre-mix fan runs, but not the correct speed.
Check if the fan runs smoothly.
•
Check the wiring.
•
Case 9: Reset button error
Too many switches on reset button in a short period of time. These error will disappear
•
after some time, or if the main power is disconnected for a while.
