What's the right position for packs and recirc fan when using ground air supply?
When I switch the packs to AUTO, I can hear the sound of air flowing, however, the temperature raises. See image "all-auto-hot.png"
When I switch the packs to off, temparature drops and stabilizes at about 22C, but now theres no sound of air flowing. See image "all-off-22c.png"
How shall I place theses switches when using ground air supply?
thanks.
