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.
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.
EXPANDED PARAMETER NAME
†
FIRST STAGE COOLING DEMAND (Y1–IN)
YES = economizing available; the system can use outside air for
free cooling when required
FIRST STAGE COOLING RELAY OUTPUT
YES = outside air being used for first stage cooling
OCCUPIED
YES = OCC signal received from space thermostat or unitary
controller
YES = 24 vac on terminal OCC
NO = 0 vac on terminal OCC
HEAT PUMP MODE
Displays COOL or HEAT when system is set to heat pump
(Non-conventional)
FIRST STAGE COOLING DEMAND (Y1-IN)
Y1–I signal from space thermostat or unitary controller for cooling
stage 1.
ON = 24 vac on terminal Y1–I
OFF = 0 vac on terminal Y1–I
