CHECKOUT
Inspect all wiring connections at the economizer module’s termi-
nals, and verify compliance with the installation wiring diagrams.
For checkout, review the Status of each configured parameter and
perform the Checkout tests.
NOTE: For information about menu navigation and use of the
keypad, see Interface Overview on page 43.
Power Up
After the W7220 module is mounted and wired, apply power.
Initial Menu Display
On initial start up, Honeywell displays on the first line and
economizer W7220 on the second line. After a brief pause, the
revision of the software appears on the first line and the second
line will be blank.
Power Loss (Outage or Brownout)
All set points and advanced settings are restored after any pow-
er loss or interruption.
NOTE: All settings are stored in non-volatile flash memory.
Status
Use the Status menu (see Table 15) to check the parameter val-
ues for the various devices and sensors configured.
NOTE: For information about menu navigation and use of the
keypad, see Interface Overview on page 43.
Checkout Tests
Use the Checkout menu (see page 48) to test the damper opera-
tion and any configured outputs. Only items that are config-
ured are shown in the Checkout menu.
NOTE: For information about menu navigation and use of the
keypad, see Interface Overview on page 43.
To perform a Checkout test:
1. Scroll to the desired test in the Checkout menu using the
▲
and
▼
buttons.
2. Press the
(Enter) button to select the item. RUN?
appears.
3. Press the
(Enter) button to start the test. The unit
pauses and then displays IN PROGRESS. When the test is
complete, DONE appears.
4. When all desired parameters have been tested, press the
(Menu Up) button to end the test.
The Checkout tests can all be performed at the time of installa-
tion or at any time during the operation of the system as a test
that the system is operable.
TROUBLESHOOTING
Alarms
The economizer module provides alarm messages that display
on the 2-line LCD.
NOTE: Upon power up, the module waits 60 minutes before
checking for alarms. This allows time for all the configured
devices (e.g. sensors, actuator) to become operational. The
exception is the SAT sensor which will alarm immediately.
If one or more alarms are present and there has been no keypad
activity for at least 5 minutes, the Alarms menu displays and
cycles through the active alarms.

EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage.
Be sure to allow enough time for compressor start-up and
shutdown between checkout tests so that you do not short-
cycle the compressors.
