Abstract
A device, and controlled solar heating system incorporating the device, for providing an electrical control signal responsive to the rate of flow of species of radiant energy through an area. The device includes means for providing an electrical input signal responsive to the rate of flow of the species of radiant energy, such as solar energy, and an electrical circuit for receiving the input signal and for providing a control signal in response to the input signal. Solar cells may provide the input signal to a Schmidt Trigger Circuit set to provide two control signals at predetermined rates of solar energy flow through an area. The device, incorporated into a solar heating system, may be used to control the circulation of fluid through solar heating panels.
