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
located after the cooling coil, in the fan section, where it is desig-
nated 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 backward 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 displays a screen sav-
er, which cycles through the Status items. Each Status items dis-
plays in turn and cycles to the next item after 5 seconds.
Table 12 — Menu Structure*
IMPORTANT: During setup, the economizer module is
live at all times.
