Abstract

An HVAC controller is described that is configured to be more intuitive and user friendly to program and operate than convention HVAC controllers. In some instances, the HVAC controller may include a touch screen interface that provides greater flexibility in displaying information to the user and/or soliciting information from the user.

Claims

1. An HVAC controller configured to control one or more components of an HVAC system, the HVAC controller comprising:

a housing;

a display secured relative to the housing;

a data port accessible from outside the housing, the data port configured to interact with an external memory device;

a controller in communication with the display and the data port, the controller configured to operate an algorithm that at least partially controls the one or more components of the HVAC system, the algorithm being configurable; and

wherein the controller is configured to read the external memory device via the data port, and to display on the display of the HVAC controller a display element for at least some of one or more configurations stored on the external memory device.

2. The HVAC controller of claim 1, wherein the controller is configured to display a display element for only those stored configurations that are compatible with the HVAC controller.

3. The HVAC controller of claim 1, wherein the HVAC controller further includes an internal memory that is in communication with the controller, wherein the controller is configured to allow a user to select a particular one of the displayed configurations, and to load the selected configuration into the internal memory for use by the algorithm of the controller during operation.

4. The HVAC controller of claim 3, wherein the controller is further configured to allow a user to preview a selected configuration before deciding if the selected configuration should be loaded into the internal memory and used by the algorithm of the controller during operation.

5. The HVAC controller of claim 4, wherein the controller is configured to allow the user to preview on the display a number of operating parameters of the selected configuration.

6. The HVAC controller of claim 5, wherein the number of operating parameters are organized in a hierarchical manner, and can be previewed through a hierarchical menu structure.

7. The HVAC controller of claim 5, wherein the controller is configured to display a display element for only those stored configurations that are compatible with the HVAC controller.

8. The HVAC controller of claim 3, wherein the controller is configured to allow a user to save a current configuration of the controller to the external memory device.

9. The HVAC controller of claim 8, wherein the controller is configured to allow a user to name the current configuration before saving the current configuration to the external memory device.

10. The HVAC controller of claim 9, wherein the current configuration is saved as a file on the external memory device, and the name of the current configuration is used as the file name.

11. The HVAC controller of claim 1, wherein each display element of the one or more configurations stored in the external memory device includes a unique configuration name.

12. The HVAC controller of claim 11, wherein each of the one or more configurations is stored as a file on the external memory device, and the unique configuration name corresponds to the name of the file.

13. The HVAC controller of claim 1, wherein the controller is configured to display the display elements for the one or more configurations stored on the external memory device in a display window with scroll bars.

14. The HVAC controller of claim 1, wherein the HVAC controller is a thermostat.

15. The HVAC controller of claim 1, wherein the HVAC controller is a thermostat having a temperature sensor in communication with the controller.

16. The HVAC controller of claim 1, wherein the data port is a USB compatible data port.

17. The HVAC controller of claim 1, wherein the data port is an Ethernet compatible data port.

18. The HVAC controller of claim 1, wherein the controller is further configured to load a logo from the external memory device via the data port, and to display the loaded logo on the display.

19. An HVAC controller configured to control one or more components of an HVAC system, the HVAC controller comprising:

a housing;

a display secured relative to the housing;

a data port configured to interact with an external memory device;

a controller in communication with the display and the data port, the controller configured to operate an algorithm that at least partially controls the one or more components of the HVAC system, the algorithm being configurable, the external memory device is not required to be accessed for the controller to operate the algorithm that at least partially controls the one or more components of the HVAC system;

wherein the controller is configured to read the external memory device via the data port, and to display on the display of the HVAC controller a display element for each of one or more compatible configurations stored on the external memory device; and

the controller further configured to allow a user to preview on the display a number of operating parameters of a selected configuration before deciding if the selected configuration should be loaded into the memory and used by the algorithm of the controller during operation.

20. The HVAC controller of claim 19, wherein the number of operating parameters are organized in a hierarchical manner, and can be previewed through a hierarchical menu structure.

21. The HVAC controller of claim 19, wherein the data port is a wireless data port.

22. The HVAC controller of claim 19, wherein the data port is a wired data port.

23. A method for configuring a HVAC controller having a data port and a user interface including a display, comprising:

reading an external memory device via the data port;

displaying on the display of the HVAC controller a display element for each of one or more configurations stored on the external memory device;

selecting a particular one of the displayed configurations via the user interface; and

loading the selected configuration into an internal memory of the HVAC controller for use by the HVAC controller during operation.

24. The method of claim 23, wherein the displaying step only displays display elements for those configurations stored on the external memory device that are compatible with the HVAC controller.

25. The method of claim 23 further comprising:

previewing a selected configuration before deciding if the selected configuration should be loaded and used by the HVAC controller during operation.

26. The method of claim 23 further comprising:

loading a logo from the external memory device via the data port into the internal memory of the HVAC controller; and

reading the logo from the internal memory and displaying the loaded logo on the display of the HVAC controller.

27. A thermostat configured to control one or more components of an HVAC system, the thermostat comprising:

a controller configured to operate an algorithm that at least partially controls the one or more components of the HVAC system in accordance with a predetermined configuration, the predetermined configuration including a plurality of operating parameters;

a touch screen LCD display secured relative to a housing;

a wireless data port configured to wirelessly interact with a portable memory device storing two or more configurations via a wireless communication link; and

wherein, the controller only displays one or more of the configurations stored on the portable memory device that are suitable for the thermostat.

28. The thermostat of claim 27, wherein the portable memory device stores one or more configurations that are not suitable for the thermostat, and the thermostat does not display the one or more configurations that are not suitable.
