With a Brinsea Oct.20, I don't trust what it says on top, I had some bad hatches because I did.
Get a spot check thermometer and put it through the hole.
To keep mine at 99.5 degrees I have to set it on top for 100.7. I had a couple of hatches where less than 25% hatched because the temp ended up being too low.
GOOD LUCK!
