ABSTRACT:
A control circuit for a solar energy heating system comprising a pair of thermistors connected in series across a source of electrical power and respectively disposed to be responsive to fluid temperature in a solar collector and in a storage tank. A negative feedback high frequency oscillator which includes a Schmitt trigger is connected to the junction of the thermistors and provides a high frequency control signal having an amplitude which varies as a function of the temperature differential between the collector and tank. An electronic switch energizes a fluid pump for transporting fluid from the solar collector to the tank when the temperature at the collector exceeds that at the tank by a preselected amount.
