I have Envision dip switch set to dehumidify yet it doesn't seem to help. Are there other settings that need changed besides SW2-4 looking at the switch 2-4 is to the left. no water comes out the drain line. Yet my portable dehumidifier runs constant with water pouring outs its drain. I have an digital Accurite temp/humidity gage ant stays about 74% which indicates high. I would like to turn off the portable as its old and noisy!
