1 question: Once the humistat reaches the desired level (40%), it will not turn back on when the humidity level in the room drops below 40? Do you know why it won't turn back on? Question #2: Doe the machine have a default humistat level? When I first turn it on, it always defaults to 60. Then I reset it to 40. Once it reach 40, the humidier will shut off, but will not come back on when it drops below 40 unless I turn the machine off and back on and the the humistat defaults to 60 again.
