This is an extension of the Tunnel Fan Groups On / Opening Size menu item. Instead of opening a curtain based on
the number of fans running, you can interlock specific tunnel fans with curtains (open the curtain based on the
number of interlocked fans running).

You can interlock up to nine specific fan groups with a curtain. 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 curtain (refer to the previous Fan Groups On / Opening Size Menu). It only allows selection of installed fans
whose “Use for Proportional Control” setting is YES.

Proportional versus Stepping
This is an extension of the Tunnel Fan Groups On / Opening Size menu item. It allows two settings:
Proportional - the curtain will open based on a percentage of the Tunnel fans running between each level in the Fan
Groups On settings. This allows a slow ramping of the opening of the curtain as the fans turn on and off.
Stepping - the curtain will open to the specified size for each level in the Tunnel Fan Groups On settings and will not
move again until the number of fans running reaches the next level. The advantage of the Stepping setting is so the
curtain does not open and close rapidly when a variable speed fan increases and decreases its speed.
