PURPOSE:To contrive certainty of action by simple constitution, by carrying out control of a solar heat collector directly through a sunshine quantity by making use of a photoelectric element. CONSTITUTION:A photoelectric element 6 through which a sunshine quantity is detected, and thermal medium circulation pump 5 of a heat collector is made to start and suspend or a number of revolutions of the pump is controlled through its output is provided on a solar heat collector. Starting and suspension and flow control of the thermal medium circulation pump 5 are performed by a control loop extending from the photoelectric element 6 to the thermal medium circulation pump 5. |
