Abstract

A zone control panel may be adapted to accommodate a method of verifying communication and/or connections between the zone control panel and one or more thermostats that are electrically connected to the zone control panel. In some cases, the one or more thermostats may be set to a particular state or condition, and the zone control panel may be adapted to sequentially or simultaneously display the particular state or condition of each of the one or more thermostats.

Claims

1. A zone control panel configured to receive electrical signals from a plurality of remotely located thermostats, wherein each thermostat corresponding to a particular zone in a conditioned space, the zone control panel comprising:

a mode selector that permits a user to put the zone control panel into a checkout mode;

a zone selector that permits the user to select a particular zone when the zone control panel is in the checkout mode; and

a display that provides the user with information related to a state of an electrical signal received by the zone control panel from the particular thermostat that corresponds to the selected zone when in the checkout mode.

2. The zone control panel of claim 1, wherein the electrical signal received by the zone control panel corresponds to a heating call signal.

3. The zone control panel of claim 1, wherein the electrical signal received by the zone control panel corresponds to a cooling call signal.

4. The zone control panel of claim 1, wherein the electrical signal received by the zone control panel corresponds to a fan call signal.

5. The zone control panel of claim 1, wherein the zone control panel is configured to sequentially display information related to the state of two or more electrical signals of each of the plurality of thermostats as the zone selector selects the corresponding zones.

6. The zone control panel of claim 1, wherein the display comprises an alphanumeric display.

7. The zone control panel of claim 1, wherein the display comprises a liquid crystal display.

8. The zone control panel of claim 1, further comprising one or more buttons that permit a user to operate the zone control panel.

9. The zone control panel of claim 1, further comprising a mode indicator light.

10. The zone control panel of claim 9, wherein the mode indicator light is configured to show when the zone control panel is in the checkout mode.

11. A zone control panel configured to receive electrical signals from two or more thermostats and to control a zoned HVAC system accordingly, the zone control panel comprising:

an alphanumeric display;

a controller coupled to the alphanumeric display, the controller structured to selectively display on the alphanumeric display a state of at least one of the electrical signals received from each of the two or more thermostats.

12. The zone control panel of claim 11 further comprising an indicator light selectively indicating a mode of the zone control panel.

13. The zone control panel of claim 11, wherein the two or more thermostats may be manipulated to a particular operating condition, and the zone control panel is configured to permit a user to select a particular thermostat and display the state of at least one of the electrical signals received from the selected thermostat.

14. The zone control panel of claim 13, wherein the zone control panel is configured to permit a user to sequentially display the state of at least one of the electrical signals received from each of the plurality of thermostats.

15. A method of installing a zone control panel that is configured to interact with a plurality of thermostats that each provide one or more electrical signals to the zone control panel, the zone control panel including a display, the method comprising steps of:

connecting the plurality of thermostats to the zone control panel;

setting each of the plurality of thermostats to an operating condition; and

displaying a state of at least one of the electrical signals received from each of the plurality of thermostats on the display.

16. The method of claim 15, further comprising a step of placing the zone control panel into a checkout mode before the displaying step.

17. The method of claim 15, wherein the setting step comprises setting each of the one or more thermostats to an operating condition by physically accessing each of the one or more thermostats.

18. The method of claim 17, wherein the setting step comprises changing the operating condition of at least one of the one or more thermostats while the zone control panel is displaying the state of at least one of the electrical signals.
