It may be a little hard to describe, but I'll try.
An engine cooling needs of the full voltage of 120 V until it is activated (you must overcome inertia and load the compressor). Operating at normal speed may even reduce the 120V. This saves electricity.
You need a power transistor connected in series with the motor. The base of the transistor connected to a capacitor and resistor values, so it take a few seconds for the transistor to be biased so that there is a certain tension is reduced through the collector and emitter. The savings could be significant.
Note: This is a simplified version of what the actual circuit.
