Abstract

A zone controller having an electronic board with a plurality of electronic components attached thereto. The electronic components are constructed and arranged to receive a plurality of signals from a plurality of thermostats and to transmit a plurality of signals to a plurality of air control devices for controlling airflow in ducts. The electronic components include a first grouping of electronic components that are not accessed to perform either installation or operation functions, a second grouping of electronic components that are accessed to perform installation functions, and a third grouping of electronic components that are only accessed to perform operation functions. A first cover is provided that covers and prevents access to the first grouping of electronic components. A second cover is provided that selectively covers and prevents access to the second grouping of electrical components but not the third grouping of electrical components.

Claims

1. An HVAC zoning control panel comprising:

(i) an electronics board;

(ii) a plurality of electronic components mounted to the electronics board, the electronic components being characterized by a first grouping of electronic components that are not accessed to perform either installation or operation functions, a second grouping of electronic components that are accessed to perform installation functions, and a third grouping of electronic components that are accessed to perform operation functions, wherein access to the first, second and third groupings of electronic components comprises manual manipulation;

(iii) a first board cover that prevents access to the first grouping of electronic components; and

(iv) a second board cover that selectively prevents access to the second grouping of electronic components but not the third grouping of electronic components.

2. The zoning control panel of claim 1, further comprising a base, where the first board cover is configured to attach to the base.

3. The zoning control panel of claim 1, further comprising a base, where the second board cover is configured to attach to the base.

4. The zoning control panel of claim 1, wherein the second board cover does not prevent access to at least a portion of the first board cover.

5. The zoning control panel of claim 4, wherein the third grouping of electronic components are accessible through the first board cover.

6. The zoning control panel of claim 1, wherein the first board cover and second board cover together cover the entire electronics board.

7. The zoning control panel of claim 1, wherein the first board cover is not readily removable.

17. The zoning control panel of claim 1, wherein the second board cover does not prevent access to at least a portion of the first board cover.

18. The zoning control panel of claim 1, wherein the second board cover includes an opening that allows access to at least a portion of the third grouping of electronic components.

19. The zoning control panel of claim 1, wherein the first cover, when in place, covers the first grouping of electronic components but provides access to the second grouping of electronic components and the third grouping of electronic components.

20. The zoning control panel of claim 19, wherein the second cover, when in place, covers the second grouping of electronic components but not the third grouping of electronic components, and wherein the second cover covers at least a portion of the first cover.

21. The zoning control panel of claim 1, wherein the second grouping of electronic components includes a plurality of wire terminals that are configured to connect wires to the zoning control panel, wherein the first cover, when in place, covers the first grouping of electronic components but provides access to at least some of the plurality of wire terminals of the second grouping of electronic components.

8. An HVAC zoning control panel comprising:

(i) an electronic board;

(ii) a plurality of electronic components mounted to the electronics board, the electronic components comprising

(a) electrical components configured to receive a plurality of signals from a plurality of thermostats;

(b) electrical components configured to transmit a plurality of signals to a plurality of dampers within air ducts;

(c) electrical components configured to transmit signals to a conditioning unit for modifying the temperature of air within air ducts;

(d) electrical components configured to provide an interface for selecting operating parameters;

(e) electrical components configured to provide an indication of a condition; and

(f) a microprocessor configured to control the transmission of signals to the dampers and conditioning unit in response to the signals received from the thermostats and parameters selected through the interface;

(iii) the electronic components including a first grouping of electronic components that are not accessed to perform either installation or operation functions, a second grouping of electronic components that are accessed to perform installation functions, and a third grouping of electronic components that are accessed to perform operation functions, wherein access to the first, second and third groupings of electronic components comprises manual manipulation;

(iv) a first board cover that prevents access to the first grouping of electronic components; and

(v) a second board cover that selectively prevents access to the second grouping of electronic components but not the third grouping of electronic components.

9. The zoning control panel of claim 8, further comprising a base, where the second board cover is configured to attach to the base.

10. The zoning control panel of claim 8, wherein the second board cover does not prevent access to the first board cover.

11. The zoning control panel of claim 8, wherein the first board cover is not readily removable.

12. The zoning control panel of claim 8, wherein the plurality of electrical components further includes a damper driver, and wherein the first grouping of electronic components comprises a damper driver.

13. The zoning control panel of claim 8, wherein the first grouping of electrical components comprises electrical components configured to receive a plurality of signals from a plurality of thermostats, electrical components configured to transmit a plurality of signals to a plurality of dampers within air ducts, electrical components configured to transmit control signals to a conditioning unit for modifying the temperature of air within air ducts, and a microprocessor.

14. The zoning control panel of claim 8, wherein the second grouping of electrical components comprises electrical components configured to provide an interface for selecting operating parameters.

15. The zoning control panel of claim 8, wherein the third grouping of electrical components comprises electrical components configured to provide an indication of a condition.

16. A method for operating an HVAC zoning control panel, the method comprising:

providing an electronics board having first, second, and third groupings of electronic components disposed thereon;

providing a first board cover that prevents access to the first grouping of electronic components of the electronics board of the HVAC zoning control panel, wherein the first grouping of electronic components are not accessed to perform either installation or operation functions;

providing a second board cover that prevents access to the second grouping of electronic components but not the third grouping of electronic components of the electronics board of the HVAC zoning control panel, wherein the second grouping of electronic components are accessed to perform installation functions, and wherein the third grouping of electronic components are accessed to perform operation functions;

performing operation functions for the HVAC zoning control panel by accessing the third grouping of electronic components with both the first board cover and the second board cover installed; and

performing installation functions for the HVAC zoning control panel by selectively removing the second board cover but not the first board cover to provide access to the second grouping of electronic components.
