Abstract

In one aspect, the invention relates to a configurable thermostat including a thermostat core having a user interface. The user interface includes a plurality of user interface keys, a display, a temperature sensor, and a temperature control. The configurable thermostat also includes a universal thermostat expansion port. The universal thermostat expansion port is disposed on the thermostat core. The universal thermostat expansion port includes at least one electrical connector. The electrical connector electrically couples a daughter board to the thermostat core, wherein the daughter board is communicately coupled to the thermostat core by an ASCII communications protocol. According to another aspect of the invention, a method for configuring a thermostat uses a personal computer with a thermostat having a user removable memory. Yet another aspect of the invention is a method for rapidly producing a thermostat having new features without needing to redesign the entire thermostat.

Claims

1. A configurable thermostat comprising:

a thermostat core including a user interface, said user interface having a plurality of user interface keys, a display, a temperature sensor, and a temperature control; and

a universal thermostat expansion port, said universal thermostat expansion port disposed on said thermostat core, said universal thermostat expansion port including at least one electrical connector, said electrical connector to electrically couple a daughter board to said thermostat core, wherein said daughter board is communicately coupled to said thermostat core by an ASCII communications protocol.

2. The configurable thermostat of claim 1, wherein said daughter board includes memory.

3. The configurable thermostat of claim 2, wherein said memory is SD memory.

4. The configurable thermostat of claim 3, wherein said SD memory is disposed in an SDIO socket situated on said daughter board.

5. The configurable thermostat of claim 1, wherein said daughter board includes a wireless communications chip set.

6. The configurable thermostat of claim 5, wherein said daughter board includes a wireless communications chip set configured for WiFi wireless network connectivity.

7. The configurable thermostat of claim 1, wherein said daughter board includes a wireless receiver configured to receive information from a broadcast signal.

8. The configurable thermostat of claim 5, wherein said daughter board includes a microcomputer, said microcomputer including programming to translate an electrical and a communication protocol between said communications chip set and said thermostat core.

9. The configurable thermostat of claim 1, wherein said at least one electrical connector mechanically supports said daughter board.

10. A method for configuring a thermostat using a personal computer comprising the steps of:

providing a thermostat having a user removable memory;

providing a personal computer;

removing said user removable memory from said thermostat;

connecting said user removable memory to said personal computer;

communicating with said user removable memory using said personal computer;

removing said user removable memory from said personal computer;

reinstalling said user removable memory into said thermostat; and

operating said thermostat in conjunction with said user removable memory to perform thermostat operational functions.

11. The method of claim 10, wherein the step of providing a thermostat having a user removable memory comprises the step of providing a thermostat having an SD user removable memory.

12. The method of claim 10, wherein the step of providing a thermostat having a user removable memory comprises the step of providing a thermostat having an SD user removable memory in an SDIO form factor.

13. The method of claim 10, wherein the step of providing a thermostat having a user removable memory comprises the step of providing a thermostat having a user removable memory including a user application program for programming said thermostat.

14. The method of claim 10, wherein the step of providing a thermostat having a user removable memory comprises the step of providing a thermostat having a user removable memory, said user removable memory including a user application program for data logging thermostat activity.

15. A method for rapidly producing a thermostat having new features without needing to redesign the entire thermostat comprising the steps of:

providing a thermostat core comprising a plurality of user interface keys, a display, an HVAC interface circuit, and a universal thermostat expansion port;

providing a requirement for a new thermostat feature that is not available in said thermostat core;

designing a daughter board suitable for plugging into said universal thermostat expansion port having said new thermostat feature;

producing said daughter board suitable for plugging into said universal thermostat expansion port; and

plugging said daughter board into said universal thermostat expansion port to create a thermostat comprising said thermostat core and said daughter board and causing said thermostat to have said new thermostat feature.

16. The method of claim 15, wherein said new thermostat feature is a wireless communication feature.

17. The method of claim 15, wherein said new thermostat feature is a memory card feature.
