You can interlock up to nine fan groups with an inlet. Press the
PLUS
or
MINUS
key to change the Interlock number
(one through nine). This menu item limits the fan groups counted when determining the appropriate position of the
inlet (refer to the previous Fan Groups On / Opening Size Menu). This menu item only allows selection of installed
fans whose “Use for Proportional Control” setting is YES.
Natural Interlock to Fan
This is an extension of the Cool Fan Groups On / Opening Size menu item. Instead of opening an inlet based on the
number of fans running, you can interlock specific fans with inlets (open the inlet based on the number of interlocked
fans running).

Proportional versus Stepping
This is an extension of the Cooling Fan Groups On / Opening Size menu item. It allows two settings:
Proportional - the inlet will open based on a percentage of the Cooling fans running between each level in the Fan
Groups On settings. This allows a slow ramping of the opening of the inlet as the fans turn on and off.

You can select each fan group only once for each inlet.
