Important - Please Read Carefully Please read the instruction on Thermostat Operation again. The Thermometer will always be sitting on the wire floor of the incubator. In a still air incubator, the closer you get to the top of the incubator, the higher the actual temperature. We have worked out scientifically the proper thermometer reading for different size eggs, when on their side on the floor and when they are in the automatic turner. When setting eggs of different sizes, you will have to use an average half way between temperature in the chart below.
Winter operation requires lowering operating temperature to prevent overheating top of eggs.
Use these temperature throughout the entire incubation period. Three days before eggs are to hatch, remove the eggs from the turner, lay them on their side on the wire floor, and increase temperature two full degrees above your operating temperature for hatching. When the turner is removed for hatching, turn adjusting screw one full turn counterclockwise. The motor on turner produces heat and this should correct this situation. Fine adjust after temperature stabilizes.
