2.
Check sensor resistance and compare it to the
curve.
3.
In the event of severe deviation replace the sensor.
Fault "A3" during commissioning
During commissioning, the control unit checks whether
the flue gas temperature sensor is correctly positioned.
If the flue gas temperature sensor is not positioned
correctly, commissioning is cancelled and fault mes-
sage A3 is displayed.
1.
Check whether the flue gas temperature sensor is
correctly inserted. See previous diagram.
