What is a Split System PCB Main and Its Key Functions?
The PCB Main, or main control board, is a complex electronic unit that performs a number of important functions to ensure the correct operation of the split system:
- Operating mode control: Ensures the selection and maintenance of the set mode (cooling, heating, dehumidification, ventilation, automatic).
- Temperature control: Receives data from temperature sensors and controls the operation of the compressor and fans to achieve and maintain the set temperature.
- Fan control: Regulates the rotation speed of the indoor and outdoor unit fans.
- Timer management: Provides programming of the air conditioner's on and off times.
- Diagnostics and protection: Processes signals from system status sensors, detects malfunctions, and activates protection systems against overloads, overheating, etc.
- Communication with peripherals: Ensures interaction with the remote control, display, and other control elements.
Main Signs of a Split System PCB Main Failure:
- The air conditioner does not turn on at all and shows no signs of life.
- The indication lights up, but the fan or compressor does not start.
- The air conditioner operates erratically, periodically turns off or restarts.
- Individual functions do not work (for example, the temperature is not regulated, the operating mode does not change).
- Incorrect error codes are displayed on the screen or there is no indication.
- A smell of burnt electronics is felt from the indoor or outdoor unit.
The Importance of Choosing an Original or High-Quality PCB Main for Replacement:
Replacing the main control board requires a responsible approach. Using an original board or a high-quality analog guarantees:
- Full compatibility with all components of your split system.
