This is solar water heating controller which is made using electronic controller and able to create excellent detection of solar panel temperature as well as that of the tank which stores the heated power. Whenever the solar panel is hotter than the stored water, the pump should run to send hot water from the panel into the hot water tank. However, when the stored water is hotter than the solar panel, the pump should be off since the stored water would otherwise be cooled by the panel. Here is solar water heating controller wiring diagram which consists of sensor 1, sensor 2, pump motor, stp60ne06, LM335Z temperature sensor, ground, IC1a, IC1b, etc.
