(under the class definition) Device comprising particular
temperature responsive means for operating a device which controls air flow to, from, or within a ventilated space.
(1) Note. Inclusion in this subclass requires specific temperature sensing and coupled operating means structure (i.e., a "means for controlling a ventilator in response to temperature" is not sufficient to inclusion in this subclass whereas a "bimetallic element operated actuating linkage for a ventilator" is sufficient for inclusion).
(2) Note. The means usually detects and responds to air temperature within the ventilated space or within an air passage leading to the space.
