The temperature controller, combined with input from two temperature sensors, controls which component?

The temperature controller utilizes input from two temperature sensors specifically to manage the heat exchanger bypass valve. This valve plays a crucial role in regulating the temperature of fluids within the system by directing the flow through the heat exchanger as necessary. By adjusting the position of the bypass valve, the temperature controller ensures that the heat exchanged is optimal for system performance, preventing overheating or inefficient cooling.

In contrast, other components like the bleed air inflow switch, ram air flow switch, and vent control lever function in different capacities that do not relate directly to the regulation of temperature through a controlled bypass valve. For instance, the bleed air inflow switch is responsible for managing the flow of compressed air used in various systems, while the ram air flow switch concerns the regulation of external air entering the system. The vent control lever directs air flow based on cockpit control inputs, which is not primarily influenced by temperature readings from sensors in the same manner. Thus, the primary function of the temperature controller aligns with managing the heat exchanger bypass valve effectively.
