The present disclosure describes a supply fan assembly including a controller, a memory operably coupled with the controller. The supply fan assembly further includes at least one environment sensor operably coupled with the controller and a fan supplying fresh air from an exterior environment into a structure according to instructions from the controller. Additionally, the operational data is generated by the at least one of the environment sensor and the controller, and the controller instructs the fan in response to the operational data generated during a pre-defined time period.

A damper control assembly includes a damper body movable between a first threshold position and a second threshold position. A motor is operably connected to the damper body, wherein the motor drives the damper between the first threshold position to determine an open position and the second threshold position to determine a closed position. A controller is operably connected to the motor and has a stall detection module that detects a first rotor-lock condition when the motor drives the damper body to the first threshold position and a second rotor-lock condition when the motor drives the damper body to the second threshold position. The controller includes a memory module for storing the first and second threshold positions for use by the controller. The damper control assembly is calibrated to drive the damper body within an operating range having the open and closed positions and that is less extensive than a mechanical range defined by the first and second threshold positions.

A combined ventilation and illumination system includes a ventilation assembly, a light fixture assembly, and a connector assembly. In an installed position, the system is installed above a ceiling of a room of building structure (e.g., a residence or workplace) to provide ventilation for the room. The system couples a light fixture to ventilation assembly below the ceiling. In the installed position, an air flow cavity is defined between the light fixture and the ceiling, where the cavity allows for air flow around the light fixture and into the ventilation assembly for eventual exhaust beyond the room in which the system is installed. The cavity includes a first critical distance that is sized according to operating parameters of a blower of the ventilation assembly to provide an adequate flow rate of intake air and to provide acceptable sound levels during operation of the system.
