Abstract

Controllers and systems for displaying servicing information via a display unit are disclosed. A controller in accordance with an illustrative embodiment of the present invention may include an interface for programming a service event display mode in the controller, and a display unit configured to display servicing information when a service event is detected by the controller. An event such as the triggering of a service indicator or the expiration of an equipment service event timer may cause the controller to display servicing information on the display unit, informing the user that servicing may be necessary or is recommended.

Claims

1. A thermostat for controlling a climate control system for a space, the thermostat comprising:

a wireless input port for establishing wireless communication between the thermostat and an external data source to enable the upload of at least one electronic image file from the external data source to the thermostat, wherein each of the at least one electronic image files stores an image that includes one or more graphical image elements, wherein at least a portion of the one or more graphical image elements is not an alphanumeric character or alphanumeric symbol;

a controller for controlling the operation of the thermostat, wherein the controller receives the at least one electronic image file uploaded via the wireless input port; and

a display responsive to the controller for displaying the image of at least one electronic image file uploaded from the external data source.

2. The thermostat of claim 1 further comprising a user interface, wherein the controller causes the image of at least one electronic image file to be displayed on the display without first requiring prompting by a user via the user interface of the thermostat.

3. The thermostat of claim 1 wherein the controller displays a first screen having at least a sensed temperature value on the display, and subsequently replaces the first screen with a second screen on the display that includes the image of at least one electronic image file uploaded from the external data source.

4. The thermostat of claim 3 wherein the second screen that includes the image of at least one electronic image file is displayed during a time period when the user is not interacting with the thermostat.

5. The thermostat of claim 3 wherein the controller subsequently displays the second screen on the display without requiring prompting by a user of the thermostat.

6. The thermostat of claim 1 wherein the display includes an LCD display.

7. The thermostat of claim 1 wherein the display includes a dot matrix display.

8. The thermostat of claim 1 wherein the display includes a touch screen display.

9. The thermostat of claim 1 wherein the electronic image file is in a jpeg file format.

10. The thermostat of claim 1 wherein the electronic image file is in a bitmap file format.

11. The thermostat of claim 1 wherein the electronic image file is in a gif file format.

12. The thermostat of claim 1 wherein the electronic image file is in a tiff file format.

13. The thermostat of claim 1 wherein the image of the at least one electronic image file is displayed during time periods when the user is not interacting with the thermostat.

14. A thermostat for controlling a climate control system for a space, the thermostat comprising:

a connector configured to receive a wired connection to an external data source and to establish a data connection with the external data source for uploading at least one electronic image file from the external data source to the thermostat;

a memory for storing the at least one uploaded electronic image file;

a display;

a controller for controlling the operation of the thermostat, wherein the controller is coupled to the display and the memory and is further configured to direct the at least one electronic image file uploaded via the connector to the memory; and

the controller is further configured to read at least one of the electronic image files from the memory and display a representation of the at least one electronic image file on the display, wherein the at least one electronic image file stores an image that includes one or more graphical image elements, wherein at least a portion of the one or more graphical image elements is not an alphanumeric character or alphanumeric symbol.

15. The thermostat of claim 14 wherein the controller causes a representation of at least one of the at least one electronic image files to be displayed on the display without requiring prompting by a user of the thermostat.

16. The thermostat of claim 14 wherein the controller causes a representation of at least one of the at least one electronic image files to be displayed on the display during a time period when the user is not interacting with the thermostat.

17. The thermostat of claim 14 wherein the controller displays a first screen having at least a sensed temperature value on the display, and subsequently replaces the first screen with a second screen on the display that includes the representation of at least one electronic image file uploaded from the external data source.

18. The thermostat of claim 17 wherein the controller subsequently displays the second screen without requiring prompting by a user of the thermostat.

19. The thermostat of claim 17 wherein the controller subsequently displays the second screen during a time period when the user is not interacting with the thermostat.

20. A thermostat for controlling a climate control system for a space, the thermostat comprising:

a wired or wireless input port for establishing a data connection with an external data source and for uploading at least one electronic image file from the external data source to the thermostat, wherein the at least one electronic image file stores a graphical image, wherein at least a portion of the graphical image is not an alphanumeric character or alphanumeric symbol;

a memory for storing the at least one uploaded electronic image file;

a display; and

a controller for controlling the operation of the thermostat, wherein the controller is coupled to the memory and the display, and is configured to read at least one electronic image file from the memory and display a first screen having at least a sensed temperature value on the display, and to display at least a second screen without requiring prompting by a user of the thermostat, wherein the second screen displays the graphical image of the at least one electronic image file uploaded through the wired or wireless input port.

21. A thermostat for controlling a climate control system for a space, the thermostat comprising:

a wired input port for establishing wired communication between the thermostat and an external data source to enable the upload of at least one electronic image file from the external data source to the thermostat, wherein the at least one electronic image file stores an image that includes one or more graphical image elements, wherein at least a portion of the one or more graphical image elements is not an alphanumeric character or alphanumeric symbol;

a display; and

a controller for controlling the operation of the thermostat, wherein the controller is coupled to the display and is configured to display the image of at least one electronic image file uploaded from the external data source on the display.

22. A thermostat for controlling a climate control system for a space, the thermostat comprising:

a wireless input port for establishing wireless communication between the thermostat and an external data source to enable the upload of at least one electronic image file from the external data source to the thermostat, wherein the at least one electronic image file stores an image that includes one or more graphical image elements, wherein at least a portion of the one or more graphical image elements is not an alphanumeric character or alphanumeric symbol;

a display; and

a controller for controlling the operation of the thermostat, wherein the controller is coupled to the display and is configured to display the image of at least one electronic image file uploaded from the external data source on the display.
