You need to have separate, calibrated thermometer and hygrometer gauges inside the unit to make sure it's correct. My first hatch I left it as is but had a LOT of late hatchers due to low temp.
It sounds like you humidity was way too high as well. I run mine at 35% humidity during incubation and 65% during the last few days.
