How does the FREON system activate?

The FREON system is designed to function automatically based on specific temperature thresholds. The correct answer indicates that the system activates automatically at 78º. This means that when the ambient temperature reaches this level, the system engages to regulate the environmental conditions effectively.

The automatic activation at this specific temperature helps ensure that the system responds without the need for user intervention, providing convenience and maintaining optimal conditions. The choice reflecting manual activation is not correct because the FREON system is designed for automatic operation. Similarly, the activation at temperatures of 68º or when temperatures drop does not align with the specifications of the system, indicating that the focus is on maintaining functionality at a higher temperature threshold for activation.
