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 Switches and the current
programmed configuration is displayed. A qualified
Service Technician, following instructions in YORK
Service Manual 160.67-M3, establishes this configura-
tion per the desired operation. This screen also serves
as a gateway to more sub-screens for defining general
system parameters.

Set Date
Access Level Required: OPERATOR
Allows the user to specify the present date. This value
is critical to logging system shutdowns accurately and
for utilizing the scheduling capabilities. When prompt-
ed to enter a date value, the user must enter the day,
month, and four-digit year (using leading zeroes as
necessary). If within range, the value will be accepted.
If out of range, the user is prompted for the information
again. At this point the user may retry the date entry, or
cancel the programming attempt.
Set Time
Access Level Required: OPERATOR
Allows the user to specify the present time. This value
is critical to logging system shutdowns accurately and
for utilizing the scheduling capabilities. When prompt-
ed to enter a time value, the user must enter the hour
and minute desired (using leading zeroes as necessary).
If the chiller is presently set to 24-hour mode, the time
must be entered in the 24-hour format. Otherwise, the
user must also select AM or PM for the entered time. If
out of range, the user is prompted for the information
again. At this point the user may retry the time entry, or
cancel the programming attempt.
Clock (Enabled / Disabled)
Access Level Required: OPERATOR
Allows the user to enable or disable the real-time clock
in order to conserve battery life. The clock will be dis-
abled during manufacturing and must be enabled at
system commissioning. In addition, when preparing
for prolonged shutdown the clock should once again
be disabled.
