In Manual mode, you can set the humidity from 0 to 6 (highest), and can separately control the heated tube from 60 to 86 degrees F. From your post, it sounds like you are on humidity 6 and temperature at 72. If that is true, you should be getting the maximum humidity in manual mode, and in a cool room I would expect to see condensation. If it is in Auto mode much more humidity using the manual mode than automatic climate control, which may not add any humidity when your ambient relative humidity is 80% or higher.
On your display, a water drop for humidity level, and a thermometer or hose temperature will be separately displayed in manual mode. In Auto mode they are in the same box. Be aware that even the highest temperature of 86 degrees is less than body temperature and will not feel warm to the touch, however it is still working. If you are using the highest humidity setting and still not getting moisture, it may be worth having the machine checked out. That would very likely be a malfunction. We know it is connected because you can see the controls on the menu.
