Abstract

A programmable thermostat is disclosed having a continuously movable indexing mechanism, such as a rotatable wheel, that allows a user to scroll or cycle through sequential time intervals ranging over a complete week to view currently programmed time intervals and to select periods of time during the week that the user wishes to program or reprogram. Such a design allows a user to easily program different temperature settings during different time intervals during the week and allows the user to easily view the programmed settings.

Claims

1. A programmable thermostat comprising:

(a) a viewing window for displaying an interval of time partitioned into discrete time units with the programmed temperature indicated for each of said time units;

(b) a continuously movable indexing mechanism for changing the display such that a movement of said indexing mechanism by a user sequentially changes the interval of time displayed in said viewing window;

said viewing window configured to display sequential time intervals ranging over a complete week through corresponding continuous movement of said indexing mechanism; and

(c) one or more user input devices for setting a temperature for a selected period of time displayed in said viewing window.

2. The programmable thermostat of claim 1 wherein said continuously movable indexing mechanism is a rotatable wheel.

3. The programmable thermostat of claim 2 wherein said thermostat has a circular profile and said rotatable wheel is positioned around the circumference of said circular profile.

4. The programmable thermostat of claim 1 wherein said one or more user input devices comprises one or more buttons.

5. The programmable thermostat of claim 4 wherein said indexing mechanism is further configured to select said selected period of time when one of said one or more buttons is pressed by a user.

6. The programmable thermostat of claim 1 wherein said week is partitioned into seven days and wherein each day corresponding to said interval of time displayed in said viewing window is also displayed in said viewing window.

7. The programmable thermostat of claim 1 wherein said indexing mechanism is selected from the group consisting of:

a touch-sensitive annular surface, a lever, and a rotatable knob; and

wherein said one or more user input devices is selected from the group consisting of;

a touch-sensitive annular surface, a lever, a rotatable knob, and a rotatable wheel.

8. The programmable thermostat of claim 1 further comprising an input for selecting heating or cooling.

9. The programmable thermostat of claim 8 further comprising a display for displaying the current time and an input for modifying the current time displayed.

10. The programmable thermostat of claim 1 wherein said viewing window is further configured for intermittently prompting or instructing a user.

11. A method of programming a programmable thermostat comprising the steps of:

(a) displaying in a viewing window an interval of time partitioned into discrete time units with the currently programmed temperature indicated for each of said time units;

(b) changing the display in said viewing window to display sequential time intervals based on movement of a continuously movable indexing mechanism by a user;

said viewing window being configured to display sequential time intervals ranging over a complete week through corresponding continuous movement of said indexing mechanism;

(c) receiving all electronic signal from one or more user input devices indicating that said user wishes to select a period of time to program;

(d) selecting said period of time in response to movement of said continuously movable indexing mechanism by said user; and

(e) setting a temperature to be associated with said selected period of time.

12. The method of claim 11 wherein time units of said selected period of time are selected by said user moving said indexing mechanism to cause movement of said time units past a marker on said viewing window.

13. The method of claim 11 wherein the step of setting a temperature comprises adjusting the temperature up or down based on electronic signals received from said one or more user input devices.

14. The method of claim 11 wherein said continuously movable indexing mechanism is a rotatable wheel.

15. The method of claim 14 wherein said thermostat has a circular profile and said rotatable wheel is positioned around the circumference of said circular profile.

16. The method of claim 11 wherein said one or more user input devices comprises one or more buttons.

17. The method of claim 11 wherein said week is partitioned into seven days and wherein each day corresponding to said interval of time displayed in said viewing window is also displayed in said viewing window.

18. The method of claim 11 wherein said indexing mechanism is selected from the group consisting of:

a touch-sensitive annular surface, a lever, and a rotatable knob; and

wherein said one or more user input devices is selected from the group consisting of;

a touch-sensitive annular surface, a lever, a rotatable knob, and a rotatable wheel.

19. The method of claim 11 further comprising the step of intermittently prompting or instructing said user.
