chiller. A subscreen with additional

Operation Mode will remain
stationary
On DynaView
™
, the user will be
presented with a single line of text
that represents the ‘top-level’
operating state of the machine. These
top-level modes are shown in the
table below. Additional information (if
it exists) regarding the machine
operating state will be available to
the user by selecting the “additional
information” button (double right
arrow) next to the top-level operating
mode. These sub-level modes are
shown in the table at left.
The TOP LEVEL MODE is the text
seen on the single top level chiller
system operating mode line. The
SUB LEVEL MODE is the text seen on
the operating mode sub-menu. The
operating mode sub-menu may have
up to six (6) lines of text displayed.
The BAS CODE is the code that will
be sent via COMM4 to the Tracer
Summit system as the chiller system

may contain multiple sub level
modes. In general, the BAS CODE
will reflect the top level mode and not
the sub level mode.
