And by the way, packs are controlled on the NG by a single ACAU (Air Conditioning Accessory Unit)


Not familiar with the 500 or 700 but, there aer two ACAUs on the 800.

These components in the EE compartment control the functions of the air conditioning system

Two pack/zone temperature controllers
* Two air conditioning accessory units (ACAU)
* Cabin pressure controllers (CPC).

The air conditioning accessory units (ACAUs) are on the E4-1 shelf.
