A Controller is a key device that manages and optimizes the operation of a solar water heating system. It monitors the temperature of the water in the solar collector and storage tank, ensuring efficient heat transfer. The controller automatically activates the circulating pump when the collector is hotter than the water in the tank, and turns it off when the temperature equalizes.
This controller is essential for maximizing the efficiency and performance of solar split systems by maintaining optimal temperature regulation and preventing overheating or unnecessary energy use.
