MENU STRUCTURE
Table 12 illustrates the complete hierarchy of menus and parame-
ters for the EconoMi$er
®
X system.
The Menus in display order are:
• STATUS
• SETPOINTS
• SYSTEM SETUP
• ADVANCED SETUP
• CHECKOUT
• ALARMS
NOTE: Some parameters in the menus use the letters MA or
MAT, indicating a mixed air temperature sensor location before
the cooling coil. This unit application has the control sensor locat-
ed after the cooling coil, in the fan section, where it is designated
as (Cooling) Supply Air Temperature or SAT sensor.
SETUP AND CONFIGURATION
Before being placed into service, the W7220 Economizer module
must be setup and configured for the installed system.
The setup process uses a hierarchical menu structure that is easy to
use. You press the and arrow buttons to move forward and back-
ward through the menus and press the button to select and confirm
setup item changes.
TIME-OUT AND SCREENSAVER
When no buttons have been pressed for 10 minutes, the LCD dis-
plays a screen saver, which cycles through the Status items. Each
Status items displays in turn and cycles to the next item after
5 seconds.
IMPORTANT: Table 12 illustrates the complete hierarchy.
Your menu parameters may be different depending on
your configuration.
For example, if you do not have a DCV (CO
2
) sensor, then
none of the DCV parameters appear and only MIN POS will
display. If you have a CO
2
sensor, the DCV MIN and DCV
MAX will appear AND if you have 2 speed fan DCV MIN
(high and low speed) and DCV MAX (high and low speed
will appear).
IMPORTANT: During setup, the economizer module is
live at all times.
