The terminal unit also includes a duct assembly including a casing and a control valve configured to coordinate with the electronic controls to manage air flow through the casing. Further, the terminal unit includes a see-through barrier coupled to the electric enclosure such that the electronics are positioned between a base of the electric disclosure and the see-through barrier.
