Our Solar Heater Controller is designed to automatically regulate the temperature of your swimming pool by controlling the flow of water through your solar panels.

On a hot day, the temperature of the water in the solar panel is warmer than the water in the swimming pool. The Controller unit will close the valve, which will cause the water to circulate through the solar panels. This will increase the pool water temperature up to the temperature that you set on the Controller.

On a cold or over cast day, the temperature of the water in the solar panel will be colder than the water in the swimming pool. The Controller unit will open the valve and the water will bypass the solar panel back in to the swimming pool, thus eliminating any loss of heat.

Once the unit is installed and your ideal temperature set, the Controller unit will automatically open and close the valve as illustrated in the diagram. This will help keep your pool at a constant temperature all year round.
