• Function: The motherboard is responsible for receiving sensor signals and controlling the operation of the compressor, fan, and other electrical components.
• Control method: Modern air conditioning motherboards mostly use microprocessor control to achieve functions such as temperature regulation, timing switch, and mode selection.
• Fault diagnosis: Many motherboards have self-diagnosis functions, which prompt users with fault codes through flashing indicator lights or displays.
• Protection function: The motherboard generally has safety designs such as overload protection, short circuit protection, and over-temperature protection to prevent equipment damage.
• Hardware components: The motherboard contains multiple electronic components, such as resistors, capacitors, diodes, and integrated circuits, which are the basis for implementing control functions.
