(under subclass 279) Apparatus in which the fluid flow control means is provided with a separate means under the control of a human operator for operating the flow control means independently of the condition sensed.
(1) Note. The manual actuating means must be specifically disclosed as operating the fluid flow control means by an independent or overriding action of the condition sensing means. The disclosure of a manual adjusting means, which might incidentally cause operation of the flow control, is not included.
