F. Pack Controllers The pack controllers 7HH (27HH) are the computers for the pack temperature control-system. They do the calculations necessary for operation of the air conditioning packs 10HM (11HM). They are installed in the racks 95VU and 96VU of the avionics compartment. They have the following functions:
-
to receive, to calculate and to send the necessary signals (ARINC 429 data bus) to the zone temperature controller 8HK,
-
to send the necessary signals to the P/BSW 6HB (7HB) on the panel 30VU in the cockpit,
-
to calculate and send the necessary signals to the air-inlet flap actuators 8HH (28HH) to open and close the ram air inlets,
-
to do the Built-In Test Equipment (BITE) tests,
-
to monitor the temperature in the ducts of the air conditioning packs and to do the correct steps if an overheat occurs,
-
to calculate and send the necessary signals to the flow control valves 8HB (11HB),
-
to control the applicable bypass valve 10HH (30HH) for pack temperature control.

F. Air Conditioning System Controllers (ACSC) The ACSC's 47HH (57HH) do also the temperature control of the packs. They do the calculations necessary for operation of the air conditioning packs 10HM (11HM). They are installed in the racks 95VU and 96VU of the avionics compartment. They have the following functions:
-
to send the necessary signals to the P/BSW 6HB (7HB) on the panel 30VU in the cockpit,
-
to calculate and send the necessary signals to the air-inlet flap actuators 8HH (28HH) to open and close the ram air inlets,
-
to do the Built-In Test Equipment (BITE) tests,
-
to monitor the temperature in the ducts of the air conditioning packs and to do the correct steps if an overheat occurs,
-
to calculate and send the necessary signals to the flow control valves 23HB (24HB),
-
to control the applicable bypass valve 10HH (30HH) for pack temperature control.
