CONFIGURATION SCREEN
overvieW
This screen is the top level of the general configura-
tion parameters. It allows programming of the time and
date, along with specifications as to how the time will
be displayed (12 or 24 hour format). In addition, the
chiller configuration, as determined by the state of the
Microboard Program Jumpers and Program Switches
is displayed. A qualified Service Technician, following
instructions in the Service Instructions (Form 160.72-
M1), establishes this configuration per the desired op-
eration. This screen also serves as a gateway to more
subscreens for defining general system parameters.
