Currently S/U only Available in Manual
Mode
– During S/U Operators sometime forget to put in manual.
Too Many Fans
– Causes Vacuum Problems.

Currently Only One Sequence.
– Off Summer Peak, not fans run. – Windward Edge Fans have diminished efficiency.
Consider Changing Sequence Based on
Wind.
– Explore Staging On Windward Fans Last.
