TEMPERATURE CONTROL – AUTO
The temperature selectors, when selected COLD will cause the ACSC to modulate the
TRIM AIR valves towards closed and when selected HOT will cause the ACSC to
modulate the TRIM AIR valves towards open. The affected compartment trim valve
will modulate to attain and maintain the selected temperature.
The selected temperature and actual temperature will be displayed on the STATUS
page and AIR CONDITIONING synoptic page.

With the TRIM AIR ON and the air conditioning PACKS in AUTO, the ACSC
modulates the Temperature Control Valve (TCV). To control pack discharge
temperature, the TCV bypasses hot air around the pack to mix with the cool air at the
Air Cycle Machine (ACM) turbine outlet.
In AUTO mode, the temperature is controlled between a minimum of 3°C to a
maximum of 70°C.
