Setup screen
Figure 29: 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 is displayed (12 hour 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 YORK YVAM Service Manual (Form 160.88-M2) , establishes this configuration for the required
operation. This screen also serves as a gateway to more subscreens for defining general system
parameters. These subscreens are listed in Table 52.
