Fan with learning mode

An apparatus, comprising:

• a fan;
• and
• a controller configured to regulate a speed of the fan according to a pre-programmed value for each of a plurality of different ambient conditions based on a first desired fan speed provided by a first user, and wherein the controller is further configured to regulate the speed of the fan according to a determined value for each of the plurality of different ambient conditions based on a second desired fan speed provided by a second user;
• wherein the controller is configured to determine the determined value for each of the plurality of different ambient conditions based upon interpolating the second desired fan speed provided by the second user.

A method of operating a fan, comprising:

• determining a first range of fan speeds corresponding to a plurality of different ambient conditions based upon input of a first desired fan speed at a first ambient condition in a first mode of operation;
• regulating operation of the fan in the first mode of operation according to the first range of fan speeds;
• and
• adjusting operation of the fan to a second mode of operation based upon input of a second desired fan speed at a second ambient condition, wherein the second mode of operation comprises a new set of fan speeds different from the first range of fan speeds, each of the new set of fan speeds corresponding to the plurality of different ambient conditions, and wherein a first rate of change of fan speed with respect to a change in the ambient condition in the first mode of operation is different from a second rate of change of fan speed with respect to a change in the ambient condition in the second mode of operation.
