る空気調和機の誤動作防止装置。 An air conditioner that has a circuit that energizes the electrical elements used in the air conditioner by opening and closing the contacts of the relay, and also has a circuit that amplifies the operating signal of the relay output from the control unit with a buffer circuit and supplies it to the relay. In a harmonic machine, a circuit is connected between the power supply and the relay that cuts off the power to the relay when there is a difference between the content of the operating signal output from the control unit and the content of the signal amplified by the buffer circuit. Features: Air conditioner malfunction prevention device.
