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 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.
IMPORTANT: During setup, the economizer module is
live at all times.
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
saver, which cycles through the Status items. Each Status items
displays in turn and cycles to the next item after 5 seconds.
