ABSTRACT:
A ventilator is selectively configured so that it can automatically open and close its louvers according to the temperature in its environment or have its louvers manually positioned in either the open or closed orientation. The louvers are disposed in an air passageway that is defined by a housing. A bimetallic coil acts through a drive element and a linkage element to automatically open and close the louvers of the ventilator. A pair of override members have respective handles accessible to the user. Manipulation of the override members enables the user to override the automatic drive element to manually open and close the louvers.
