Abstract
Abstract A system for remote temperature supervision and control of a large, complex multispace air-conditioning installation with a central station connected over a transmission circuit to a plurality of groups of remote stations for controlling apparatus in multispaces. A central console at the central station has supervision and control apparatus which can be selectively connected by coded messages over the transmission circuit to any one of the remote stations. The central console has a display means for selectively displaying a schematic showing of the apparatus of any one group of remote stations so that upon sending a coded message to a particular remote group, the particular remote group sends a coded message back to the central console to select a schematic showing of the particular group, whereby further supervision and control can be accomplished from the central console upon referring to the schematic.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
147 words
A system for remote supervision and control of a multistation installation wherein a central station is connected over a transmission channel to a plurality of groups of remote stations having apparatus to be supervised and controlled and coded messages are used to and from the central and groups of stations comprising: a console at said central station comprising supervision and control apparatus and display means for selectively displaying a showing of the apparatus associated with the remote stations of said plurality of groups, means associated with said console for sending over said channel a coded message to a particular group of stations, and means associated with said particular group of stations upon receiving said coded message for returning a second coded message to said console for selectively actuating said display means for displaying a showing of the apparatus associated with the remote stations in said particular group.
Claim 2
Independent Claim
147 words
A system for remote supervision and control of a multistation installation wherein a central station is connected over a transmission channel to a plurality of groups of remote stations having apparatus to be supervised and controlled and coded messages are used to and from the central and groups of stations comprising: a console at said central station comprising supervision and control apparatus and display means for selectively displaying a showing of the apparatus associated with the remote stations of said plurality of groups, means associated with said console for sending over said channel a coded message to a particular group of stations, and means associated with said particular group of stations upon receiving said coded message for returning a second coded message to said console for selectively actuating said display means for displaying a showing of the apparatus associated with the remote stations in said particular group.
Claim 3
Dependent Claim
23 words
The invention of claim 1 wherein said display means comprises a random access slide projector for selectively placing a schematic on a screen.
Claim 4
Dependent Claim
59 words
The invention of claim 1 wherein: said display means comprises a plurality of random access projectors each having a plurality of slides for selectively placing a schematic on a screen and; said second coded message having a first portion for designating which of said plurality of projectors is energized and a second portion for designating which slide is used.
Claim 5
Dependent Claim
46 words
The invention of claim 1 wherein said schematic of the apparatus can be viewed on said display means by a human operator to select particular apparatus to be supervised and controlled whereby a subsequent coded message can be sent from said console to said particular apparatus.
Claim 6
Dependent Claim
84 words
The invention of claim 1 wherein the installation is an air-conditioning installation and the plurality of groups are located in different physical areas of the installation and said apparatus associated with said remote stations is air-conditioning apparatus comprising; means associated with said console for reading and controlling temperature whereby upon reviewing said showing further coded messages can be sent to said particular group to measure and control temperature at selected remote stations and still further coded messages can be sent back to said console.
Claim 7
Dependent Claim
45 words
The invention of claim 1 wherein said display means comprises a first and second component and, said second coded message comprises a first portion for selecting one of said components to be used and a second portion for selecting the particular showing to be displayed.
Claim 8
Dependent Claim
48 words
The invention of claim 1 wherein the groups of remote stations each have a panel comprising an electrical circuit, said circuit being adapted to be changed to preselect the particular second coded message whereby a schematic showing can be indicative of the apparatus associated with the group selected.
Claim 9
Dependent Claim
29 words
The invention of claim 1 wherein said display means comprises a storage means for storing a plurality of showings, said storage being selectively energized by said second coded message.
