Zusammenfassung:	An improved humidifier system for adding humidity to an air stream of an HVAC system. The humidifier system includes an air path that is configured to accept air from a first HVAC duct and return air to a second HVAC duct. A damper is disposed in the air path to selectively substantially block the flow of air in the air path, or to substantially not block the flow of air in the air path. In some cases, the damper may be a motorized damper, and the humidifier system may include a controller that is configured to cause the motorized damper to not substantially block the flow of air in the air path during a call for humidifier operation, and to substantially block the flow of air in the air path after the call for humidifier operation ends. Alternatively, the damper may be manually actuated, and an HVAC controller may be configured to notify when the damper should be moved (e.g. between seasons).
