Increased fan duty cycle from 20% to 30% an hour ago.

Some numbers to get a feeling on what the unit is doing right now:

Outside temp: 19°C (Fresh air comes from here)
Attic Temp: 26°C (This is where suction side is pulling air from right now)
Fresh air temp 20.4 (might be a bit warmer as outside as pulling air from inside an open roof).
Inlet air: 23°C (So Air going to the house is warmed by 3°C compared to outside).
Exit Air: 20.6°C (Cooled down from 26°C most likely).

I think there can be gained more if there is more airflow. Will increase to 50% now. But looking at the graphs it looks like inlet air still rises (so does attic temp and fresh air).
