Abstract
Apparatus to override the primary pneumatic circuitry of an air distribution system during warm up cycles. Means are provided for nullifying the pressure signal, indicative of ambient temperature, to which the flow controller responds. In the preferred embodiment, the override means comprises a bimetallic helical element which operates to bleed the pneumatic thermostat's air supply, thereby reducing the temperature indicative signal to zero.
