I have been thinking about it, and I could be wrong, but something doesn't make scene to me. I think either your humidity senor is off, or your not reading it correctly. Because Like I said 16% is extremely low. I live in the desert and our humidity is higher than that during this time of year. You said you were in Cleveland Ohio, so I checked the weather there, and it says currently you were at 86%. Now there will be differences between inside and outside humidity levels, but nothing even close to a 70% difference. Not withough't running Dehumidifiers constantly...
