This is for Dometic that have 3 speed fan. Doug

A. Auto Fan
When “AUTO” fan is selected, the fan speed will vary depending on the difference
between the temperature set-point and the room temperature. In “AUTO” fan, the
compressor and fan will cycle ON and OFF with the thermostat.
When the difference is:
8 °F / °C or more The fan operates on HIGH
5 to 7 °F / °C The fan operates on MED
4 °F / °C or less The fan operates on LOW
