How variable stage cooling works
When the temperature is below the
idle range
temperature, the fan is off.
When the temperature reaches the
idle range
temperature, the fan runs at the
idle speed
. The fan
continues to run at the
idle speed
until the temperature rises to the
set point
temperature.
When the temperature is between the
set point
and
on differential
temperatures, fan speed increases or
decreases proportionally with the temperature.
When the temperature is at or above the
differential
temperature, the fan runs at full speed.

Fan speed
Fan speed increases as the temperature rises, or
decreases as the temperature falls.
The fan runs at
idle speed
.
The temperature band between the
idle range
and the
set point
is sometimes called the
idle band
.
The fan is off when the temperature is below
idle range
.
The fan runs at full speed.
