The display interface has several options for viewing the status of the System, its Modules, and the 
environment being controlled. The status readings for Modules are available under the Main Module 
and Expansion Module # options, and status readings for the System are available under the System 
Status option or on the scrolling status screens.

Note: Only the Main Module of a System has a display interface. Return temperature and 
humidity readings displayed on the scrolling status screens are an average of the readings from 
each of the Modules.
If the System is off, the readings will be the values from the sensors of the Main Module. 

When the display interface is idle, it scrolls through nine screens of status information. Press the up or 
down arrow key to interrupt the automatic scrolling and view a specific status screen.

The Module status screens contain information for each Module in a System.

for each Module. This screen has the same format as the Temp & Humidity scrolling status screen, but 
the values displayed are only for the selected Module.
