How variable cooling stages work

When the temperature is below the
off at
temperature, the fan is off.

When the temperature rises above the
off at
temperature, the fan runs at the
idle speed
. The fan
continues to run at the
idle speed
until the temperature rises to the
idle at
temperature.

When the temperature is between the
idle at
and
on full at
temperatures, fan speed increases or
decreases proportionally with temperature.

When the temperature is above the
on full at
temperature, the fan runs at full speed.
If you need to connect more cooling elements than you have relays, and you are
not using all the variable stages, you can use any available variable stage as an
ON/OFF stage.

Set the idle speed to 100% and
off at
to the temperature at which you want the
stage to switch on/off.
You no longer have “variable” speed or power; you have either “ full on ” or “ full
off ” , the same as a regular cooling element. The
idle at
and
on full at
settings
have no effect when you use a variable stage this way.
