    We turned the fan to auto early this afternoon per all of your advice. So far, the rh has dropped to 60%. I turned the thermostat down another degree to see how much more it will help. I will call the contractor in the morning.

    Thanks for your suggestions.

    ps. we should turn the fan back to "on" during the winter months??
    you vent an attic so you do not get icycles in the winter, give it a whirl with the attic fan off. Nothing to lose by trying if the rh does not plummet after a couple days then turn the fan back on.
