The Min Econo % is the position the economizer holds during
occupied mode when it is not enabled for operation due to
Outdoor Air or Wetbulb Temperature.

During economizer control, the economizer damper is allowed
to move open or closed, as required, at a rate controlled by this
value. Use this to speed up or slow down the operation of your
economizer. The larger the number, the slower the damper
moves.
