Is the speed/output a high/medium/low type deal or a specific temperature?

  The outdoor unit can vary the frequency of the compressor drive to track a desired refrigerant temperature in the face of varying load from the indoor unit. As the indoor air comes closer to the desired temperature, it will cool off the returning refrigerant less than when there is a large delta-T. The outdoor unit can adjust the compressor speed to closely match the heat transfer and run continuously at a lower speed rather than cycling on/off. There is a minimum speed below which the compressor can't run [and so would have to cycle], but in general the outside unit is smoothly variable. The indoor unit fan speeds are only loosely connected to this. (The higher the indoor fan speed, the greater the heat transfer and load on the compressor, all else being equal.)
