MENU STRUCTURE

eters 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.

Before being placed into service, the W7220 Economizer mod-
ule must be setup and configured for the installed system.
The setup process uses a hierarchical menu structure that is
easy to use. Press the
▲

▼

and backward through the menus and press the button to select
and confirm setup item changes.
TIME-OUT AND SCREEN SAVER
When no buttons have been pressed for 10 minutes, the LCD
displays a screen saver, which cycles through the Status items.
Each Status items displays in turn and cycles to the next item
after 5 seconds.
Table 7 illustrates the complete hierarchy. Your menu pa-
rameters 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.
