System has a demand for cooling. The fan is operating at a medium speed.

FAN SPEED - Depending  on your model, the

 button allows you to toggle between four or five modes of operation: LOW, MEDIUM, HIGH and AUTO.

When fan speed AUTO FAN mode (SYSTEM mode AUTO, COOL or HEAT) is selected, fan speed automatically varies depending on the difference between  
the unit’s set point on the control panel and the actual room temperature. When the system detects a wide difference between the set point and the actual 
room temperature the fan speed increases to HIGH for a period of time. The fan speed decreases, in step, as the temperature difference decreases. When the 
room temperature matches the system's set point, fan speed returns to the original setting.
