Abstract

A control unit for a swimming pool electrolytic cell. The control unit includes a housing containing a logic module. An electrical connection is provided to connect the logic module to an electrical supply to receive power therefrom. An electrical connection is provided to connect the logic module to electrodes of the cell. A data outlet is provided to send control signals from the logic arrangement to a variable speed pump. The logic module is configured to: selectively supply power to the electrodes to energize the electrodes; and control the output of the pump, when the pump is active, to suit electrolytic chlorination.

Claims

1. A control unit for a swimming pool electrolytic cell, comprising:

a housing containing a logic module;

a first electrical connection component adapted to connect the logic module to an electrical supply to receive power therefrom;

a second electrical connection component adapted to connect the logic module to electrodes of the cell; and

a data outlet adapted to send control signals from the logic module to a variable speed pump;

wherein the logic module is configured or configurable to

selectively supply power to the electrodes to energize the electrodes; and

control the output of the pump when the pump is active.

2. The control unit of claim 1, wherein the pump is configured to operate at a plurality of discrete performance settings.

3. The control unit of claim 2, wherein the pump is configured to operate at three discrete performance settings.

4. The control unit of claim 2, wherein the logic module is configured or configurable to generate the control signals to control the pump to deliver a lowest of the discrete settings when the electrodes are energized.

5. The control unit of claim 1, wherein the logic module is configured or configurable to selectively supply power and control in accordance with a timetable.

6. The control unit of claim 5, wherein the timetable includes two or more periods in which the pump is active and the logic module is configured or configurable to control the output of the pump to deliver, during at least one of the periods, an output which differs from the output during at least one other of the periods in which the pump is active.

7. A water treatment system, comprising:

a control unit;

an electrolytic cell; and

a variable speed pump;

wherein the control unit includes

a housing containing a logic module;

a first electrical connection component adapted to connect the logic module to an electrical supply to receive power therefrom;

a second electrical connection component adapted to connect the logic module to electrodes of the cell; and

a data outlet adapted to send control signals from the logic module to a variable speed pump; and

wherein the logic module is configured or configurable to

selectively supply power to the electrodes to energize the electrodes; and

control the output of the pump when the pump is active

8. A pool installation, comprising:

a body of water; and

a water treatment system configured and arranged to sanitize the body of water, the water treatment system comprising

a control unit;

an electrolytic cell; and

a variable speed pump;

wherein the control unit includes

a housing containing a logic module;

a first electrical connection component adapted to connect the logic module to an electrical supply to receive power therefrom;

a second electrical connection component adapted to connect the logic module to electrodes of the cell; and

a data outlet adapted to send control signals from the logic module to a variable speed pump; and

wherein the logic module is configured or configurable to

selectively supply power to the electrodes to energize the electrodes; and

control the output of the pump when the pump is active.
