Abstract

A zone control panel that is easy and intuitive to use and to program. In some embodiments, a zone control panel may be configured to have an easy to use, single level menu structure with, for example, a configuration mode and/or a checkout mode. The configuration mode may, if present, include a number of menu screens sometimes without any sub-menu levels. Likewise, the checkout mode may, if present, include a number of menu screens sometimes without any sub-menu levels. A mode selector may be provided to select a particular mode, after which, the menu screens that correspond to the selected mode may be sequentially displayed to the user. Other features and aspects are also disclosed.

Claims

1. A zone control panel for an HVAC system, the zone control panel providing control signals to zone control dampers of the HVAC system, the zone control panel capable of controlling a maximum number of zones, the zone control panel comprising:

a user interface; and

a controller coupled to the user interface, wherein the controller is configured to accept via the user interface an indication of a number of zones to be controlled by the zone control panel, the indicated number of zone to be controlled can be less than the maximum number of zones that the zone control panel is capable of controlling, the controller executing a control algorithm for controlling the zone control dampers, wherein the control algorithm is influenced by the indicated number of zones to be controlled.

2. The zone control panel of claim 1 wherein the user interface includes a number of buttons and a display, where the controller is coupled to the number of buttons and the display.

3. The zone control panel of claim 2, wherein the controller is configured to provide one or more menu screens on the display that prompts a user to indicate the number of zones to be controlled by the zone control panel via one or more of the buttons.

4. The zone control panel of claim 1 wherein an input to the control algorithm includes the indicated number of zones to be controlled by the zone control panel.

5. The zone control panel of claim 1 further comprising an indicator that corresponds to each zone, wherein each indicator indicates when the corresponding zone is active.

6. The zone control panel of claim 5 wherein each indicator indicates when the corresponding zone is in an open state and/or a closed state.

7. The zone control panel of claim 1, wherein the controller is configured to accept via the user interface an indication of a thermostat type for each of at least some of the plurality of zones.

8. The zone control panel of claim 1, wherein the controller is configured to accept via the user interface an indication of a thermostat type for each of the number of zones to be controlled by the zone control panel.

9. The zone control panel of claim 8, wherein the zone control panel is configured to interpret signals from each connected thermostat based on the indicated thermostat type for each of the number of zones to be controlled by the zone control panel.

10. A zone control panel providing control signals to zone control dampers of an HVAC system, the zone control panel configured to control a maximum number of zones, the zone control panel comprising:

a user interface that permits a user to specify a number of zones that are or will be connected to the zone control panel out of the maximum number of zones; and

a display panel that displays the number of zones specified;

wherein the number of zones specified can be less than the maximum number of zones.

11. The zone control panel of claim 10 wherein the zone control panel includes a control algorithm, wherein an input to the control algorithm includes the number of zones that are or will be connected to the zone control panel.

12. The zone control panel of claim 10, wherein the zone control panel is configured to permit a user to specify a thermostat type for each of the number of zones via the user interface.

13. The zone control panel of claim 10, further comprising a plurality of LEDs configured to provide a visual indication of a status of each of the maximum number of zones.

14. The zone control panel of claim 13, wherein the zone control panel is adapted to light an LED corresponding to each of the number of zones, and to not light an LEDs corresponding to any zone that is not specified as part of the number of zones.

15. The zone control panel of claim 13, wherein the plurality of LEDs are configured to provide a first color to indicate when a zone damper of a corresponding zone is closed, and a second color to indicate when the zone damper of the corresponding zone is open.

16. The zone control panel of claim 15, wherein the first color is red and the second color is green.

17. The zone control panel of claim 10, wherein the user interface includes a display and a number of buttons, wherein the number of buttons include a NEXT button, a BACK button, a first ARROW button and a second ARROW button.

18. A zone control panel for an HVAC system adapted to control a plurality of zones, each zone having a thermostat with a thermostat type, the zone control panel comprising:

a user interface; and

a controller coupled to the user interface, wherein the controller is configured to accept via the user interface an indication of a thermostat type for each of at least some of the plurality of zones.

19. The zone control panel of claim 18, wherein the zone control panel is configured to interpret signals from each connected thermostat based on the indicated thermostat type for each of the at least some of the plurality of zones.

20. A method for operating a zone control panel that is adapted to control a maximum number of zones, the method comprising the steps of:

inputting by a user a number of zones that are connected or will be connected to the zone control panel, wherein the number of zones that are connected or will be connected to the zone control panel is equal to or less than the maximum number of zones;

controlling the number of zones using a control algorithm, wherein an input to the control algorithm includes the number of zones that are connected or will be connected to the zone control panel.

21. The method of claim 20 wherein the control algorithm controls the number of zones differently depending on the number of zones that are connected or will be connected to the zone control panel.
