Operating principle

A thermostatic sensor sensing the water temprature to control the valves closing or opening .When the water temperature below 8?. This causes the sensor to move and open a tiny passage so that water can drain out, this prevents water from freezing inside the pipe. When the temperature below 4 ?,the valve opened completely. The water will be flow out from the solar panel . When the temperature above 8?, the valve will be closed.
