CAS message is displayed when the bypass electric valve is not closed and:
-the duct temperature reaches or exceeds 230°C (446°F), or
-the nose gear is down and turbofan brake operating.

DISTRIBUTION

The distribution system is divided into:
-
the cockpit conditioned air system,

-
the cabin conditioned air system (for passengers, equipment and hold).

AIR CONDITIONING HOT SYSTEM SCHEMATIC
Temperature control valves
The temperature control valves of the cabin and cockpit systems are identical but differ in operation.
Each assembly consists of two butterfly valves, mechanically linked and operated in an opposing direction by a single motor. The motor receives inputs from either the automatic or manual temperature control system of the associated controller.
Even if the cabin temperature control valve is in full hot position, the cold butterfly valve is not fully closed, allowing a volume of air to pass through the ECU.
Each temperature control valve is supplied through the associated air conditioning valve.
The air mass through each valve is directed into two ducts: -one duct supplies hot air flow to the associated jet pumps in the cabin and cockpit distribution system, -the other duct supplies an air mass to a common duct, which directs it through the cold air unit.

Cabin ducts

The cabin air conditioning ducts are routed within the lower side of the left and right hand cabin side consoles.
Passenger and crew conditioned air ducts may be manually interconnected to allow either the cabin or the cockpit distribution system to supply both ducting systems. The manual interconnection valve is located on the lower right-hand side of the cabin area.
