Abstract

A thermostat system is provided that comprises a base thermostat for providing basic thermostat control and a portable information display (PID) unit, or dockable display, that provides an improved user interface. The PID unit can be docked to the base thermostat by being releasably mounted on top of a front portion of the base thermostat. The base thermostat provides control of an environmental control system, allowing the regulation of the temperature in a building. The PID unit may be used when it is mounted to the base thermostat or un-mounted from the base thermostat. The PID unit provides an improved user interface and experience over the base thermostat.

Claims

1. A portable information display (PID) unit comprising:

a wireless communication interface for communicating with a base thermostat coupled to an environmental control system;

a docking mechanism for releasably mounting the PID unit to the base thermostat; and

a display for displaying environmental control system information retrieved from the base thermostat.

2. The portable information display unit of claim 1, wherein the PID unit provides control of the environmental control system by communicating with the base thermostat.

3. The portable information display unit of claim 2, further comprising an environmental sensor.

4. The portable information display unit of claim 3 wherein the environmental sensor is calibrated relative to an environmental sensor in the base thermostat when docked.

5. The portable information display unit of claim 3, wherein the environmental control system is controlled based on the environmental sensor of the PID unit when remote from the base thermostat.

6. The portable information display of claim 1, wherein the PID unit comprises a docking interface for communicating with the base thermostat and charging a battery of the portable thermostat control when mounted to the base thermostat.

7. The portable information display of claim 6 further comprising exchanging security key information with the base thermostat through the docking interface, the security key information for communication with a smart grid infrastructure.

8. The portable information display unit of claim 1, further comprising a mapping mode to associate a location of the PID unit to one or more environmental control system control settings to allow the base thermostat to automatically control the environmental control system in accordance with the associated one or more environmental control system control settings when the PID unit is in the location.

9. The portable information display unit of claim 8, wherein the PID unit determines its location using one or more of:

data from one or more accelerometers accumulated since the last time the PID unit was mounted to the base thermostat;

triangulation from a plurality of wireless communication devices; and

an indication from a user of the PID unit.

10. The portable information display unit of claim 1 wherein the display is a touch screen display for displaying information received from the base thermostat and for providing user input to base thermostat.

11. A thermostat system comprising:

a base thermostat coupled to an environmental control system to control operation of at least one component of the environmental control system; and

a portable information display (PID) unit comprising a display, providing a docking mechanism to releasably mount the PID unit to the base thermostat, the PID unit communicating with the base thermostat to enable controlling the base thermostat via the PID unit.

12. The thermostat system of claim 11 wherein the base thermostat further comprises a display and wherein the PID unit covers the display of the base thermostat when mounted to the base thermostat.

13. The thermostat system of claim 12 wherein the base thermostat further comprises an environmental sensor for sensing an environmental condition to control the environmental control system relative to the sensed environmental condition and the PID unit further comprises an environmental sensor for sensing an environmental condition and for controlling the environmental control system relative to the sensed environmental condition by communication with the base thermostat.

14. The thermostat system of claim 13 wherein the base thermostat environmental sensor or PID unit environmental sensor can be calibrated relative to each other when the PID unit is docked to the base thermostat.

15. The thermostat system of claim 11 further comprising a charging interface between the base thermostat and the PID unit to provide a charging current to the PID unit when mounted to the base thermostat

16. The thermostat system of claim 15, wherein the charging current is from a 24 VAC transformer provided by the environmental control system to the base thermostat.

17. The thermostat system of claim 11, further comprising a data interface between the base thermostat and the PID unit to provide a communication interface to the PID unit when mounted to the base thermostat.

18. The thermostat system of claim 17 wherein the data interface is for exchanging security key information for communication with a smart grid infrastructure between the base thermostat and the PID unit.

19. The thermostat system of claim 11 further comprising a wireless data interface between the base thermostat and the PID unit to provide a communication interface to the PID unit.

20. The thermostat system of claim 11, further comprising:

at least one additional base thermostat for controlling an environmental condition in a zone separate from the base thermostat, wherein the PID unit may communicate with the at least one additional base thermostat and be mounted to the at least one base thermostat.

21. The thermostat system of claim 11, wherein the PID unit is releasably mountable to the base thermostat using a docking mechanism that is part of the PID unit, part of the base thermostat, or part of both the PID unit and the base thermostat.
