Abstract

A thermostat includes a display and an illumination device that is configurable to illuminate the display in a partial illumination mode and full illumination mode. In the partial illumination mode the illumination device generates a light intensity sufficient to review the settings of the thermostat without generating heat of a sufficient amount to disrupt thermostat measurements. The full illuminated condition is actuated upon interaction with the thermostat. Once interaction with the thermostat is completed the illumination device thermostat returns to the partially illuminated condition.

Claims (20)

1. A thermostat assembly comprising:
a display for communicating information; and an illumination device for illuminating said display, said illumination device actuatable between a non-illuminated mode, a partially illuminated mode and a fully illuminated mode.
2. The assembly as recited in claim 1, wherein said display comprises a liquid crystal display device.
3. The assembly as recited in claim 2, wherein said illumination device comprises a backlight.
4. The assembly as recited in claim 1 including a controller for adjusting said illumination device between said non-illuminated mode and said fully illuminated mode, and said partially illuminated mode and said fully illuminated mode.
5. The assembly as recited in claim 4, including a user interface for adjusting a thermostat parameter, said controller adjusting an illumination level of said illumination device to said fully illuminated mode responsive to actuation of said user interface.
6. The assembly as recited in claim 5, wherein said fully illuminated mode continues for a desired time after actuation of said user interface.
7. The assembly as recited in claim 5, wherein said partially illuminated mode comprises partially illuminating said display without activation of said user interface.
8. The assembly as recited in claim 5, wherein said partially illuminated mode includes changing to said fully illuminated mode in response to actuation of said user interface, and returning to said partially illuminated mode after actuation of said user interface.
9. The assembly as recited in claim 1, including a lumens sensor for sensing a light level.
10. The assembly as recited in claim 9, wherein said illumination device illuminates said display responsive to a light level detected by said lumens sensor.
11. A method of illuminating a thermostat comprising the steps of:
a. selecting between a partially illuminated mode and a fully illuminated mode of an illumination device for illuminating a display; and b. illuminating said display according to said selected mode.
12. The method as recited in claim 11, wherein said partially illuminated mode comprises illuminating said display at an illumination level between no illumination and full illumination and increasing the illumination level to full illumination responsive to user interaction with a user interface.
13. The method as recited in claim 12, including returning to a partial illumination level responsive to no interaction with said user interface for a desired wait period.
14. The method as recited in claim 11, wherein said fully illuminated mode comprises no illumination of said display until interaction with said user interface, and resuming no illumination of said display responsive to no interaction with said user interface for a desired wait period.
15. The method as recited in claim 11, including the step of detecting a light level surrounding said thermostat, and illuminating said display responsive to a detected light level.
16. A system control panel assembly comprising:
a display means for displaying information relating to operation of a system;
an illumination means for illuminating said display means according to a non-illumination mode, a partially illuminated mode and a fully illuminated mode.
17. The assembly as recited in claim 16, including a control means for adjusting said illumination means between said non-illumination mode, said partially illuminated mode and said fully illuminated mode.
18. The assembly as recited in claim 16, including a light sensing means for providing information indicative of light conditions surrounding said display means.
19. The assembly as recited in claim 16, including a user input means for setting a desired illumination mode.
20. The assembly as recited in claim 19, wherein illumination at a partially illuminated level illuminates said display device at a light level less than a full illumination level until said user input means is actuated, wherein said illumination means illuminates said display device at said full illumination level for a predetermined period.
