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. Press the

▲

and

▼

arrow buttons to move forward and back-

ward through the menus and press the

(Enter) 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 sec-

onds.

IMPORTANT: Table 11 illustrates the complete hierarchy.

Menu parameters may be different depending on the con-

figuration. For example, if there is no DCV (CO

2

) sensor,

then none of the DCV parameters appear and only MIN

POS will display. If there is a CO

2

sensor, the DCV MIN

and DCV MAX will appear AND if there is a 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.
