Sometimes a mid sensor goes bad and needs replaced. It senses the fan speed and pressure. Although not common, here's a reminder on how to do it if we have to do it again.
Acc to Zehnder the sensor is not broken quite often. You just have to clean it. I tried to blow out the differencial pressure sensor with the 2 nozzles with my mouth but it didn't work. Than I took a bicycle pump with a small nozzle for a football. I put it 1cm in front of the 2 nozzles. It worked fine and it's running without any issue for 2 weeks now. Before the sensor didn't work correctly.

Very good. I‘ve tried this on both sides and the Unit works without error. Used a compressor with 6 bar.
Thank you for this Great instructions. 👍

It is worth setting the machine to service mode before doing anything, so that it does not get stuck when the bypass is removed.
Is this the sensor eha?
clarify eha..? Q units have a mid-sensor and an upper sensor.
