Abstract

A system includes a microcontroller for controlling a fan particularly suited to be mounted in a window. The microcontroller monitors and responds at relatively high sampling rates to the actual and desired temperatures of the room associated with the fan. The microcontroller senses a predetermined difference between the desired and actual temperatures to generate the speed, forward-reverse drive and/or on-off controls of the fan and so that the operation of the fan closely tracks the temperature conditions of the room being serviced by the fan.
