Mine is a Coleman A/C with a digital thermostat with the same settings. I just leave mine on Auto, which on mine runs the fan at the same speed as if the switch was on Hi. When I switch it to Low it only makes a slight decrease in fan speed. When itís hot outside I donít see any reason to run it on Low anyway.
