Ok I am not sure if I am just not getting it or not but. My bator will not get above 90 degrees with the factory setting. So I turned off the unit, put everything to off then turned on 5, 4, 3, 2, 1 let the light flash and then turned off all of the numbers except 5. The temp is still stuck at 90. How do I get the temp up to 99 to hatch out chicken eggs? Do I turn the 5 on and then off while the unit is on? Is that how to make the temp go up by 5 degrees each time? So I would do that 2 times? As I said I am not getting it from the directions.
