ER41

The error ER41 indicates shutdown due to the minimum flow not being reached during check-up (FL19) or during normal and modulation operation (FL20).
If the detected flow value is lower than the parameters set in FL19 and FL20 (Primary air regulator → Set flow), the stove will trigger the ER41 alarm.
Cause: Incorrect reading by the flow meter (FCS).

Actions to take:

• Clear the error and restart the stove.
• If the error recurs, check the wiring.
• Clear the error, deactivate the FCS (A24 = 0 in Primary air regulator - Settings) and perform a startup.
• If the error does not occur, replacement of the depressimeter is recommended.
