Abstract

Improvements in a thermostat for HVAC control and an irrigation controller for sprinkler control are constructed each with a Base Unit and a removable User Interface Unit. The dual-function Base Unit is configurable for use as either a thermostat or an irrigation controller. The Base Unit has a connector for connection to a separate User Interface (UI) Unit. The separate UI Unit has a display, controls, and I/O Connector for connection to a Base Unit or an external computer. The UI Unit adaptively operates as a thermostat interface or irrigation interface, as is appropriate for the configuration of a connected Base Unit. The UI Unit can be connected via its I/O Connector to a PC, tablet PC, or smart phone for configuration of operational control settings using application software. The configuration settings are transferred from a UI Unit to a Base Unit upon connection via the I/O Connector.

Claims

1. A thermostat and an irrigation controller each with removable user interface comprising:

a thermostat for control of an HVAC system and an irrigation controller for control of a sprinkler system comprised of a base unit and a user interface unit each in its own enclosure;

said base unit is attached to a wall or protective enclosure and which has an input/output connector for message communication with a user interface unit;

said user interface unit is attachable to said base unit for message communication via an input/output connector;

wherein operational control settings are stored in said base unit;

wherein said base unit is capable of performing its control functions according to its operational control settings whether or not said user interface unit is attached;

wherein said user interface unit contains a display and controls for changes to one or more operational control settings by a user, and

wherein changes made by said user to said operational control settings are transferred from said user interface unit to said base unit while said user interface unit is attached to said base unit, thereby providing said operational control settings for said base unit.

2. The thermostat and an irrigation controller each with removable user interface from claim 1 wherein said operational control settings are stored in both said base unit and said user interface unit;

said operational control settings in said user interface unit are changeable when said user interface unit is removed from said base unit and said operational control settings are transferred from said user interface unit into said base unit upon attachment of the said user interface unit to base unit, thereby providing said operational control settings for the base unit.

3. The thermostat and an irrigation controller each with removable user interface from claim 1 wherein said base unit is configured with firmware and/or switches and/or jumpers to function either as a thermostat or irrigation controller.

4. The thermostat and an irrigation controller each with removable user interface from claim 1 wherein said user interface unit is configured with firmware and/or switches and/or jumpers to function either as a thermostat or irrigation controller user interface.

5. The thermostat and an irrigation controller each with removable user interface from claim 4 wherein said user interface unit adaptively functions either as a thermostat controller user interface or an irrigation controller user interface depending on functions of said base unit to which said user interface unit is attached.

6. The thermostat and an irrigation controller each with removable user interface from claim 2 wherein said user interface unit simultaneously stores operational control settings for both a thermostat and an irrigation controller.

7. The thermostat and an irrigation controller each with removable user interface from claim 2 wherein said user interface unit connects and communicates with a PC, tablet PC, and/or smart phone via its said input/output connector for the purpose of changing its operational control settings.

8. The thermostat and an irrigation controller each with removable user interface from claim 1 wherein different versions of said user interface unit with specific features and or appearance can be used interchangeably on a said base unit.

9. The thermostat and an irrigation controller each with removable user interface from claim 1 wherein said user interface unit further includes a radio and can be used as a wireless remote control for other base units and/or compatible wireless devices.

10. The thermostat and an irrigation controller each with removable user interface from claim 1 wherein said base unit and said user interface unit further includes a radio in said base unit and can be used as a wireless remote control for one or more other base units and/or compatible wireless devices when said user interface unit is attached.

11. The thermostat and an irrigation controller each with removable user interface from claim 9 wherein said user interface unit further uses a same message protocol for said input/output connector and said radio.

12. The thermostat and an irrigation controller each with removable user interface from claim 10 wherein said base unit further uses a same message protocol for said input/output connector and said radio.

13. The thermostat and an irrigation controller each with removable user interface from claim 1 wherein said user interface unit and said base unit further includes a radio in both said user interface unit and said base unit and a temperature sensor in said user interface unit such that said user interface unit provides remote thermostat temperature and control.

14. The thermostat and an irrigation controller each with removable user interface from claim 1 wherein said user interface unit copies and stores historical performance information from said base unit when said user interface unit is attached to said base unit.

15. The thermostat and an irrigation controller each with removable user interface from claim 14 wherein said user interface unit connects and communicates with a PC, tablet PC, and/or smart phone via said input/output connector for sending said historical performance information retrieved from said base unit.

16. The thermostat and an irrigation controller each with removable user interface from claim 1 wherein said user interface unit further includes a radio and displays operational status from one or more wireless hazardous condition detectors, including at least one location of hazardous conditions including smoke, or combustion detection and carbon monoxide level.

17. The thermostat and an irrigation controller each with removable user interface from claim 1 wherein said base unit further includes a radio that is used to display operational status from one or more wireless hazardous condition detectors, including at least one location of hazardous conditions including smoke, or combustion detection and carbon monoxide level.

18. The thermostat and an irrigation controller each with removable user interface from claim 1 wherein said base unit and said user interface unit comprises a thermostat which further includes a radio in said base unit and/or in said user interface unit that operates said HVAC system in order to mitigate a hazardous condition upon wireless notification of smoke or combustion detection.

19. The thermostat and an irrigation controller each with removable user interface from claim 1 that receives rainfall information for purposes of suspending or enabling irrigation.

20. The thermostat and an irrigation controller each with removable user interface from claim 1 wherein said base unit communicates with a PC, tablet PC, and/or smart phone via a wireless communications link for purposes of configuration, control, and/or monitoring.

21. The thermostat and an irrigation controller each with removable user interface from claim 1 wherein said base unit communicates with the Internet via a wireless communications link for purposes of configuration, control, and/or monitoring.
