Figure 50: Setup screen
This screen is the top level of the general configuration 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 establishes this
configuration per the desired operation. This screen also serves as a gateway to more subscreens
for defining general system parameters.
