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 control panel for entering and/or selecting a watering schedule, the control panel including a first portion of a connecting device;

a memory having a stored operational program including a watering program for executing the watering schedule;

a plurality of switch circuits for energizing a plurality of valves;

a processor connected to the memory and configured to execute the operational program and control the switch circuits in accordance with the watering schedule; and

at least one feature module including a second portion of the connecting device for mating with the first portion of the connecting device for operatively connecting the feature module to the processor, the feature module having at least one feature selected from the group consisting of;

a) programming for unlocking at least a portion of a comprehensive set of functional features of the operational program,

b) additional memory to execute additional features not otherwise executable by the processor,

c) new programming for execution by the processor, and

d) a microcontroller and programming to enable the feature module to communicate with sensors.

2. The landscape controller of claim 1 wherein the control panel includes a slot for removably receiving the feature module.

3. The landscape controller of claim 1 wherein the control panel is a removable face pack.

4. The landscape controller of claim 1 wherein the feature module is a USB thumb drive.

5. The landscape controller of claim 1 wherein the feature module and the operational program are configured so that the feature module will only unlock predetermined functional irrigation features on a predetermined controller and not on any other controllers.

6. The landscape controller of claim 1 and further comprising a plurality of receptacles for each receiving a removable station module including a portion of the switching circuits.

7. A landscape controller, comprising:

a control panel for entering and/or selecting a watering schedule, the control panel including a first portion of a connecting device;

a memory having a stored operational program including a watering program for executing the watering schedule;

a plurality of receptacles for each receiving a removable station module including a plurality of switch circuits for energizing a plurality of valves;

a processor connected to the memory and configured to execute the operational program and control the switch circuits in accordance with the watering schedule;

at least one feature module including a second portion of the connecting device for mating with the first portion of the connecting device for operatively connecting the feature module to the processor, the feature module having at least one feature selected from the group consisting of;

a) programming for unlocking at least a portion of a comprehensive set of functional features of the operational program,

b) additional memory to execute additional features not otherwise executable by the processor,

c) new programming for execution by the processor, and

d) a microcontroller and programming to enable the feature module to communicate with sensors.

8. The landscape controller of claim 7 wherein the control panel includes a slot for removably receiving the feature module.

9. The landscape controller of claim 7 and further comprising a housing configured to support the control panel and wherein the control panel is a face pack that is removable from the housing.

10. The landscape controller of claim 7 wherein the feature module is a USB thumb drive.

11. The landscape controller of claim 7 wherein the feature module and the operational program are configured so that the feature module will only unlock predetermined functional irrigation features on a predetermined controller and not on any other controllers.

12. The landscape controller of claim 7 and where the station module is an encoder module that operates a plurality of valves through a plurality of decoder circuits.

13. A landscape controller, comprising:

a control panel for entering and/or selecting a watering schedule, the control panel including a first portion of a connecting device;

a memory having a stored operational program including a watering program for executing the watering schedule;

an encoder circuit for energizing a plurality of valves through decoder circuits;

a processor connected to the memory and configured to execute the operational program and control a plurality of switch circuits in accordance with the watering schedule; and

at least one feature module including a second portion of the connecting device for mating with the first portion of the connecting device for operatively connecting the feature module to the processor, the feature module having at least one feature selected from the group consisting of;

a) programming for unlocking at least a portion of a comprehensive set of functional features of the operational program,

b) additional memory to execute additional features not otherwise executable by the processor,

c) new programming for execution by the processor, and

d) a microcontroller and programming to enable the feature module to communicate with sensors.
