Abstract

A landscape controller includes a housing and a control panel in the housing. The control panel includes a display and at least one manual control that enables a user to enter and/or select a watering schedule. A memory is provided for storing an operational program for carrying out the watering schedule. A processor is connected to the memory and is capable of executing the operational program. A connecting device in the control panel operatively connects at least one feature module to the processor. The controller further includes station control circuitry controlled by the processor that enables the processor to selectively energize a plurality of valves to deliver water to sprinklers in accordance with the watering schedule.

Claims

1. A landscape controller, comprising:

a housing;

a back plane housed by the housing;

a control panel mounted to the housing, the control panel including at least one manual control that enables a user to enter and/or select a watering schedule, a display, a memory for storing an operational program for carrying out the watering schedule, a processor capable of executing the operational program, and at least one connecting device;

at least one feature module inserted into the control panel operatively connected to the processor via the at least one connecting device, and configured to provide the control panel with additional functionality not available without the at least one feature module; and

station control circuitry controlled by the processor that enables the processor to selectively energize a plurality of valves to deliver water to sprinklers in accordance with the watering schedule, the station control circuitry configured to be removably insertable on the back plane.

2. The landscape controller of claim 1 wherein the control panel is a face pack that is removable from the housing with the feature module received in the connecting device and the face pack is programmable separate from the housing in regard to the functionality changes imparted by the feature module.

3. The landscape controller of claim 1 wherein the station control circuitry is mounted in a plurality of station modules that are removably insertable in corresponding receptacles in the housing.

4. The landscape controller of claim 1 wherein the housing includes a back panel in which the control panel is removably mounted and a door that covers the control panel.

5. The landscape controller of claim 4 wherein the station control circuitry is mounted in a plurality of station modules that are removably insertable in corresponding receptacles in the back panel.

6. The landscape controller of claim 5 further comprising the back plane mounted in the back panel, wherein the receptacles establish communication paths between the plurality of station modules and the processor through the back plane.

7. The landscape controller of claim 1 wherein the connecting device includes at least one mating electrically conductive contact.

8. The landscape controller of claim 1 wherein the connecting device is mounted in a slot in the control panel.

9. The landscape controller of claim 1 wherein the operational program includes a comprehensive set of features capable of being executed by the processor and the feature module enables a predetermined sub-set of the features.

10. The landscape controller of claim 1 wherein the feature module includes additional memory that enables the processor to execute at least one feature not otherwise executable by the processor.

11. A landscape controller, comprising:

a housing;

a control panel associated with the housing including at least one manual control that enables a user to enter and/or select a watering schedule, a display, and a connecting device;

a memory storing an operational program for carrying out the watering schedule;

a processor capable of executing the operational program;

a feature module attached to the control panel, operatively connected to the processor via the connecting device, and configured to provide the control panel with additional functionality not available without the feature module; and

station control circuitry controlled by the processor that enables the processor to selectively energize a plurality of valves to deliver water to sprinklers in accordance with the watering schedule.

12. The landscape controller of claim 11 wherein the control panel is a face pack that is removable from the housing with the feature module received in the connecting device and the face pack is programmable separate from the housing in regard to the functionality changes imparted by the feature module.

13. The landscape controller of claim 11 wherein the station control circuitry is mounted in a plurality of station modules that are removably insertable in corresponding receptacles in the housing.

14. The landscape controller of claim 11 wherein the housing includes a back panel in which the control panel is removably mounted and a door that covers the control panel.

15. The landscape controller of claim 14 wherein the station control circuitry is mounted in a plurality of station modules that are removably insertable in corresponding receptacles in the back panel.

16. The landscape controller of claim 15 further comprising a back plane mounted in the back panel, wherein the receptacles establish communication paths between the plurality of station modules and the processor through the back plane.

17. The landscape controller of claim 11 wherein the connecting device includes at least one mating electrically conductive contact.

18. The landscape controller of claim 11 wherein the connecting device is mounted in a slot in the control panel.

19. The landscape controller of claim 11 wherein the operational program includes a comprehensive set of features capable of being executed by the processor and the feature module enables a predetermined sub-set of the features.

20. The landscape controller of claim 11 wherein the feature module includes additional memory that enables the processor to execute at least one feature not otherwise executable by the processor.

21. A landscape controller, comprising:

a plurality of station modules having a plurality of switch circuits for energizing a plurality of valves;

a housing including a rear panel having a plurality of receptacles configured to removably receive the plurality of station modules;

a feature module;

a face pack removably mounted in the rear panel and configured to enable a user to enter and/or select a watering schedule, the face pack including a memory comprising a stored operational program for executing the watering schedule, a processor connected to the memory and configured to execute the operational program and control the plurality of switch circuits in the plurality of station modules in accordance with the watering schedule, and a connecting device to enable the feature module to be removably connected to the face pack to establish a communications path with the processor, the memory further comprising a watering program including at least one locked irrigation feature;

the feature module configured to unlock the at least one locked irrigation feature programmed into the watering program when the at least one feature module is connected to the face pack, the processor configured to execute the unlocked at least one irrigation feature, and the feature module not interchangeable with any of the plurality of the station modules.
