Shown is the remote control receiving and display circuit of the Xinke KI;R-28GW/BP inverter air conditioner indoor unit . IC201 is a remote control receiving
circuit. It receives the infrared light signal sent by the remote control transmitter, and outputs the control signal through photoelectric conversion, amplification, filtering and shaping in IC201.
The signal is sent to the Iyj@ pin of the microprocessor IC104. The microprocessor uses this signal as the basis for indoor control. , the circuit of the outdoor unit is controlled. The @, ②, ⑦, and ⑥ pins of
the microprocessor (CPU) output LED display drive signals to display the working status of the air conditioner.
