Patent ID: 8918218

Claim:
A Demand Control Ventilation (DCV) system for a building, comprising: a demand control ventilation device having a damper and a controller, the damper having a range of damper positions for controlling a flow of outside air into the building, and the controller controlling the damper positions such that a desired flow of outside air is drawn through the damper and into the building; a remote monitoring device located remotely from the demand control ventilation device but in communication with the controller of the demand control ventilation device, the remote monitoring device having a user interface, wherein the remote monitoring device is configured to alert a user via the user interface of the remote monitoring device to a detected fault of the demand control ventilation device; wherein the remote monitoring device is located within the building and readily accessible to a user of the building; and wherein the controller is configured to calibrate the demand control ventilation device, at a time determined by the controller, utilizing calibration parameters that are inputted into the remote monitoring device by a user, the calibration parameters including a minimum calibration ventilation rate and a maximum calibration ventilation rate.
