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.
