Abstract
PURPOSE: To prevent unnecessary overshoot from ocurring and protect critical scalds due to ejection of hot water by clipping integrated sum when the present load being operated is beyond the capacity of the hot water heater.
CONSTITUTION: A bridge circuit is composed of a hot water temperature sensor 7 and resistors 10, 21, 22 and the central points D,E are input respectively to input terminals 12a, 12b of an operational amplifier 12. The potential D corresponding to the supplying hot water is input to the negative input terminal of an operational amplifier 23 and a partical potential of a supplying hot water temperature sensor 24 and a resistor 25 is input. The gain of the operational amplifier 23 is determined by a resistor 26 and the resisting value of a supplying hot water flow sensor 27. The output of the operational amplifier 23 is sent to a comparator 28 and compared with the potential divided by resistors 29, 30. A relay 33 is energized by the output of the comparator 28, a contact 34 is closed, a transistor 13 is controlled through an operational amplifier 36 making up a voltage follower circuit.
