the design CFM of outdoor air to meet the ventilation
requirements of the conditioned space during normal
operation. Whenever the indoor fan motor is energized,
the dampers open up to one of two pre-selected posi-
tions – regardless of the outdoor air enthalpy. Dampers
return to the fully closed position when the indoor fan
motor is de-energized. Dampers shall fully close on
power loss.
