This isn't simple.
760/780 models which have Electronic Climate Control (ECC) will turn on aux fan below 8 MPH if ambient temp is higher than 86 F.
740/760/780 models all will turn on aux fan if the switch in radiator senses temp over approximately 225F.
There is a kit that was available to install a relay to turn on aux cooling fan at idle to improve a/c performance that can be fitted.
The fan can stick on any time key is on if switch or relay is stuck.

You don't mention a problem. Is your fan running all the time?
