Shutoff on Open -- If "yes" is selected, the variable speed fans will
not operate when the curtains are opened.

programmed as follows:
Max Speed 100%

Min Offset -10º

Light Strip Control
This feature is added for those applications which require the
restriction of natural light for production. When light strip control is
activated, it will ask for a time to begin, inches to drop, inches first
drop, and end time. "Inches to Drop" is the distance from the top of the
curtain opening to the bottom of the light strip. The curtains will not
rise above this setting during light hours. "Inches first Drop" should be
the distance you desire the curtain to open on the first drop from dark
to light.
Nite Vent Program
This program is only operative if the light strip control is enabled.
When using this program, the controller will allow natural ventilation
during the hours you select. This will save on energy costs by
minimizing the use of power ventilation when it is dark. The controller
will ask for a "Begin Cycle PM" and an "End Cycle AM". Remember
when setting up the system to select times before sunrise.
