Claim 9:
10. 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 one or more & sensors such that the controller is capable of deactivating the ventilation blower in response to a sensed condition, thereby placing the ventilation blower into a first alternate mode and overriding the constant ventilation of air at the target ventilation flow rate of the selected normal mode.
