Alarm "airflow can't be reached"

LucyandJean:
Thanks!!

So the 2 clear hoses on the burner are just for flow measurement?

Yes  :)

LucyandJean:
Thanks it worked!

Could you tell me what the benefits of the airflow regulation are over the regulation with fan speed? Is it worth fixing it, and if yes, could you work me through the steps to do it?

Thanks a lot!

Air flow regulation is an attempt to measure the air flow and regulate based on the pressure that is measured.
When it works it is very accurate, but several things can interfere with that measurement.
For example, dust in the hoses, a sharp bend on the hose, or a hole in the hose.

Using fan numbers is just as effective.
However, without the possibilities of incorrect adjustment based on incorrect pressure measurements.
Forget the flow regulation, it's not worth the effort.

Hello, I'm experiencing the same issue with my RTB10 boiler.
I often get the alarm "air flow can't be reached" after compressor clean cycle.
My only solution is to unplug and clean the 2 transparent hoses on the burner, clear the alarm then restart the controler. It is very unconvenient and I wonder if could use the same solution as LucyandJean, using the fan numbers instead of the air flow measurement.
Coud you please give me advice regarding this case ?

Best regards,

Max
