Depending on your HVAC system you may need to reference the DesignSpecification:OutdoorAir object elsewhere (in addition to the Sizing:Zone object and the Controller:MechanicalVentilation object). For the AirTerminal:SingleDuct:VAV:Reheat object you need to select the corresponding OutdoorAir object under 'Design Specification Outdoor Air Object Name' otherwise the terminal unit will not be controlled for outdoor air flow. If this input is left blank, minimum OA may not be provided to the zone at every hour.
