1. A ventilation system for a building, the building defines an outdoor area and an indoor area, the ventilation system comprising:
a ventilation blower configured to deliver air along a ventilation path from at least one of:
the indoor area to the outdoor area, and
the outdoor area into the indoor area; and
a controller operatively coupled to the ventilation blower,
wherein the controller comprises a manual input for selection of one of a plurality of normal modes, each of the plurality of normal modes corresponds with a target ventilation flow rate that can be associated with a number of rooms of the building and an amount of floor space of the building,
wherein, when in a selected normal mode, the ventilation blower is configured to maintain the target ventilation flow rate of the selected normal mode in response to a change in static pressure differential between the outdoor area and the indoor area,
wherein, the controller further comprises an alternate mode,
wherein, in the alternate mode, one or more sensors are configured to trigger a deviation from attempting to maintain the target ventilation flow rate corresponding to the selected normal mode.
