The control that stops the condensing unit if the head pressure climbs too high is classified as a - safety control.

Safety controls are protective devices that shut the system down when something unsafe could cause damage. If head pressure climbs too high, it signals that the condenser or refrigerant flow isn’t behaving normally, and continuing operation could harm the compressor or other components. The safety control responds by cutting power to the compressor, stopping the condensing unit to prevent damage. The actual sensing component is the high-pressure switch, which triggers this protective action. A pressure regulator would only tune pressure during normal operation, not shut the system off when limits are exceeded, and a thermal overload protects the motor from overheating, not the refrigerant pressure.
