Menu Structure
Table 11 illustrates the complete hierarchy of menus and pa-
rameters 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 mod-
ule must be set up and configured for the installed system.
The setup process uses a hierarchical menu structure that is
easy to use. Press the
▲
and
▼
arrow buttons to move forward
and backward through the menus and press the
(Enter) but-
ton to select and confirm setup item changes.
Time-Out and Screensaver
When no buttons have been pressed for 10 minutes, the LCD
displays a screen saver, which cycles through the Status items.
Each Status item displays in turn and cycles to the next item af-
ter 5 seconds.
IMPORTANT: Table 11 illustrates the complete hierar-
chy. 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.
