Figure 36: 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, following instructions
in Service Manual (Form 160.69-M1-C) , establishes this configuration per the desired operation. This
screen also serves as a gateway to more subscreens for defining general system parameters.
