A Module is an independent Computer Room Air Conditioner (CRAC) that operates
based on its own temperature and humidity sensors.
based on its own temperature and humidity sensors.
System
A System is a set of one to three Modules or CRACs. System
operation is based on an average of the combined temperature and
humidity sensors of all the Modules in the System. The Modules in a
System work together as a single unit to increase cooling capacity.

In a System, one of the Modules is designated as the Main Module and the rest of modules are
designated as Expansion Modules. The Main Module is the controller for all the Modules in the
System. It contains the Programmable Customer Input/Output Module (PCIOM) boards, the
webcard, and establishes communications with the Building Management System (BMS).
