Cooling Test
The COOL submenu is used to change output status for the
individual 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 controlled
normally to maintain proper unit operation when set for automatic
transition. The IDF SPEED TEST and ALL ODFSPD TEST can
be changed as needed for testing. These fans 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
individual heat stages, gas or electric. The COOL service test
outputs 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 sub m enu is u sed to ex ecute all th e
app licable tests to th e sy stem au to m atically. Th ese in clu d e
independent components, cooling, heating, and system. Table 5
shows the steps taken during the independent, cooling, and
heatin g au to m atic tests. Th e Hold time rep resen ts 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 enter
measured data and complete a service report.
