[Equest-users] Night Cycles

[Robby Oylear]

I use this option whenever applicable in my proposed and baseline systems.
 I can't understand why it would cause an issue with the reviewer unless
you were trying to claim that your proposed system only used zone fans
while your baseline system 6 turned the AHU on.

As you say, the baseline system does not have zone fans and thus has no
option but to run the AHU at night.  Your proposed system should be modeled
and controlled as described in the project documents.  If the description
of operations states that the AHU will not activate on a call for night
heating, then the zone fans only option would be applicable.
