Thank you. I'll take your advice. Ciao.

Earlier today, I removed the "Gegenstrom-/Enthalpiewärmetauscher". It was clean and not damaged.

As of your question, I'm sorry, I don't remember. Considering that a possible cause can be attributed to the different type of filter used for the intake (F7) and for the expulsion of air (M5), earlier today I replaced them with two M5 filters. Nothing changed: there is a ~ 600 RPM difference, yet. Regards.

Seat Flo_Schneider, Thank you for your response. I forgot to mention that when I checked the system the outside temperature was well above zero degree Celsius and that no preheater is installed. I understand that the Vitovent adapts the speeds of the two ventilators to maintain the airflow settings but, in my case, I think the difference is too high (even if no default message is displayed and the device apparently is working well). Viele Grüße

Hi, Sorry for not writing in German. I have a Vitovent 300-W with LB-1 controlling unit in operation since October 2018. I recently noticed that at Level 3 (195 m3/h in/out) the supply air fan runs 650 RPM faster than the exaust fan. Neddless to say, the ducting was done in a workmanlike manner, the vents are of an appropriate shape and size, and the filters are regularly replaced. Is this normal? Grüße
