General Information
Modules, Systems, and Groups
NetworkAIR Modules and Expansion Modules can be combined electronically to create Systems and Groups.
Module
A Module is an independent Computer Room Air Conditioner (CRAC) that operates based on its own temperature and humidity sensors.
System
na0267a
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.
Main Module
Expansion Module 1
na0269a
Expansion Module 2
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).
Note: When using the System configuration, only the Main Module display will be operational. The Expansion Module displays will not operate.
