What is the correct thermostat setting for normal cooling?

For normal cooling, turn the Operation Knob to the High Cool setting and set the Thermostat control to the desired temperature mark, with the mid-point being a good starting position. The 5 or 6 position on the thermostat is the recommended setting for average conditions. If the room temperature is not satisfactory after a reasonable time, adjust the control to a cooler or warmer setting as appropriate. (Page 6)
