Its primary function is to execute the commands from the system's thermostat and manage the operational sequences of the outdoor unit, including:

• Starting and stopping the compressor.
• Controlling the outdoor fan motor speed.
• Managing defrost cycles in heat pump applications.
• Monitoring system pressures and temperatures.

Any operational adjustments should be made via the indoor thermostat or by a qualified technician using specialized diagnostic tools.
