<h2 style="font-size:20px; margin-top:20px;">Core Functions</h2>
<p style="line-height:1.6;">
The control board acts as the central processing unit of the air conditioning system. It receives input signals from sensors such as temperature and pressure, then processes these signals to regulate compressor frequency, fan speed, and valve operation.
</p>
<p style="line-height:1.6;">
By managing AC and DC inverter signals, the board ensures efficient energy control and stable system performance. It coordinates communication between key components, enabling smooth startup, operation, and built-in protection functions.
