Press the TEST button on the SystemVu™ interface anytime to
access the Test menu. Service Test mode can only be turned ON/
OFF at the unit display. Once turned ON, other entries may be
made with the display or through CCN. To turn Service Test mode
on, change the value of TEST MODE to ON. To turn service test
mode off, change the value of TEST MODE to OFF. Service Test
mode will be automatically turned off based on keypad inactivity
and the Service Mode Test Time out (TEST MODE TIMEOUT).
NOTE: Service Test mode may be password protected. Refer to
Basic Control Usage section for more information. Depending on
the unit model, factory-installed options, and field-installed acces-
sories, some of the Service Test functions may not apply.
Independent Outputs
The INDEPENDENTS submenu is used to change output sta-
tus for the economizer, Humidi-MiZer
®
system valves, power
exhaust stages, crankcase heaters, the alarm relay, as well as
perform a compressor bump test. These independent outputs
can operate simultaneously with other Service Test modes. All
outputs return to normal operation when Service Test is turned
off. The compressor bump tests cannot be run while running
cooling tests and will automatically turn off after one minute.
Fan Test
The FAN TES TS submenu is used to change speed for the in-
door fan and outdoor fans. The outdoor fan speeds can be con-
trolled individually or all together with the ALL ODF SPD
TEST. The outdoor fan and indoor fan transition type points in-
form the test routine how to handle the fans while running the
cooling or heating tests. Automatic will automatically transi-
tion the fans as the cooling or heating tests change, while the
Manual transition will only run the fans as set by the test
points.
Cooling Test
The COOL submenu is used to change output status for the in-
dividual compressors and Humidi-MiZer system operation.
The HEAT submenu service test outputs are reset to OFF for
the cooling service test. Indoor fans and outdoor fans are con-
trolled normally to maintain proper unit operation when set for
automatic transition. The IDF SPEED TEST and ALL ODF-
SPD TEST can be changed as needed for testing. These fan
points show the requested speed, not actual speed. All normal
cooling faults and alerts are functional.
Heating Test
The HEAT submenu is used to change output status for the indi-
vidual heat stages, gas or electric. The COOL service test out-
puts are reset to OFF for the heating service test. Indoor fan is
controlled normally to maintain proper unit operation when set
for automatic transition. The IDF SPEED TEST can be
changed as needed for testing and shows the requested speed not
actual speed. All normal heating faults and alerts are functional.
NOTE: When the IGC fan on command (IGC FAN REQUEST)
is active, the fan may run when not expected.
Automatic Test
The AUTOMATIC TEST submenu is used to execute all the
applicable tests to the system automatically. These include in-
dependent component, cooling, heating, and a system one.
Table 5 shows the steps taken during the independent, cooling,
and heating automatic tests. The Hold time represents the time
at which that control waits before moving on to the next step.
The AUTO SYSTEM TEST will execute the independent auto
test, then the cooling auto test, then the heating auto test. At the
end of the system auto test a prompt will ask if you want to en-
ter measured data and complete a service report.
