Abstract

An apparatus for treating addresses employed in an environmental control network that involves at least one control unit communicating with a plurality of components, each respective component of the plurality of components having an address selected from a predetermined number of address values, includes: an address extending unit coupled with the at least one control unit and with at least one coupled component of the plurality of components. The address extending unit treats each address for each coupled component to establish a respective unique treated address for each coupled component. The at least one control unit identifies each respective component by the respective treated address.

Claims

1. An apparatus for treating addresses employed in an environmental control network, comprising:

a control unit configured to communicate with;

at least one other control unit over said network; and

a master control unit; and

an address extending unit coupled to said control unit and configured to communicate with a plurality of components including modular control units and comfort sensors for sensing parameters within a zone controlled by said modular control units, each modular control unit having an address selected from a predetermined number of address values, said address extending unit configured to treat each of said selected addresses to establish a unique treated address for each of said plurality of components so that said master control unit can identify each said component by its said treated address.

2. An apparatus for treating addresses employed in an environmental control network as recited in claim 1 wherein said treating employs mathematical manipulation of at least one said selected address for said plurality of components.

3. An apparatus for treating addresses employed in an environmental control network as recited in claim 1 wherein said treating employs signal manipulation of at least one said selected address for said plurality of components.

4. An apparatus for treating addresses employed in an enviromental control network as recited in claim 2 wherein said treating further employs signal manipulation of at least one said selected address for said plurality of components.

5. An apparatus for treating addresses employed in an environmental control network as recited in claim 2 wherein said mathematical manipulation effects multiplication of at least one said selected address for said plurality of components by a factor.

6. An apparatus for treating addresses employed in an environmental control network as recited in claim 2 wherein said mathematical manipulation effects addition of a value to at least one said selected address for said plurality of components.

7. An apparatus for treating addresses employed in an environmental control network as recited in claim 6 wherein said value is at least equal with said predetermined number.

8. An apparatus assisting address assignment in an environmental control network, comprising:

a control unit configured to communicate with;

at least one other control unit over said network; and

a master control unit; and

an address extending unit coupled to said control unit and configured to communicate with a plurality of components including modular control units and comfort sensors for sensing parameters within a zone controlled said modular control units, each modular control unit having an address selected from a predetermined number of address values, said address extending unit configured to treat each of said selected addresses to establish a unique treated address for each of said plurality of components so that said master control unit can identify each said component by its said treated address, wherein said treating employs mathematical manipulation of said selected address.

9. An apparatus assisting address assignment in an environmental control network as recited in claim 8 wherein said treating employs signal manipulation of at least one said selected address for said plurality of components.

10. An apparatus assisting address assignment in an environmental control network as recited in claim 8 wherein said mathematical manipulation effects multiplication of each said selected address by a factor.

11. An apparatus for treating addresses employed in an environmental control network as recited in claim 8 wherein said mathematical manipulation effects addition of a value to least one said selected address for said plurality of components.

12. An apparatus for treating addresses employed in an environmental control network as recited in claim 8 wherein said value is at least equal with said predetermined number.

13. A method for treating addresses employed in an environmental control network the method comprising the steps of:

(a) providing an address extending unit coupled with a control unit and with a plurality of components including modular control units and comfort sensors for sensing parameters within a zone controlled said modular control units, each of said modular control unit having an address selected from a predetermined number of address values, wherein said address extending unit communicates with said plurality of components and said control unit communicates with at least one other control unit and a master control unit;

(b) operating said address extending unit to treat each said selected address for said plurality of components to establish a unique treated address for each of said plurality of components;

(c) operating said master control unit to identify each said component by its said treated address.

14. A method for treating addresses employed in an environmental control network as recited in claim 13 wherein said treating employs mathematical manipulation of at least one said selected address for said plurality of components.

15. A method for treating addresses employed in an environmental control network as recited in claim 13 wherein said treating employs signal manipulation of at least one said selected address for said plurality of components.

16. A method for treating addresses employed in an environmental control network as recited in claim 14 wherein said treating further employs signal manipulation of at least one said selected address for said plurality of components.

17. A method for treating addresses employed in an environmental control network as recited in claim 14 wherein said mathematical manipulation effects multiplication of at least one said selected respective address for said plurality of components by a factor.

18. A method for treating addresses employed in an environmental control network as recited in claim 14 wherein said mathematical manipulation effects addition of a value to at least one said selected address for said plurality of components.

19. A method for treating addresses employed in an environmental control network as recited in claim 18 wherein said value is at least equal with said predetermined number.

20. A method for treating addresses employed in an environmental control network as recited in claim 16 wherein said mathematical manipulation effects addition of a value to at least one said selected address for said plurality of components.
