RCC SETUP SCREEN

FIG. 21 00521VIPC

OVERVIEW

This screen is accessed from the RCC Setpoint Screen. This screen shows the general configuration parameters for this OptiView Remote Control Center. It allows programming of the time and date, along with specifications as to how the time will be displayed (12 or 24 hour format). This time is used for display purposes on the OptiView Remote Control Center. It is not used to reset individual chiller clocks and has no effect on individual chiller schedules. This screen also serves as a gateway to more sub-screens for defining general RCC system parameters.

None

PROGRAMMABLE

Clock (Enabled / Disabled)

Allows the user to enable or disable the real-time clock in order to conserve battery life. The clock will be disabled during manufacturing and must be enabled at system commissioning. In addition, when preparing for prolonged shutdown the clock should once again be disabled.

Set Date

Allows the user to specify the present date. When prompted 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

Allows the user to specify the present time. When prompted 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.

12/24 Hr

Allows the user to specify the format in which the time will be presented to the user. This setpoint will only affect the display of the time on the OptiView RCC panel and on all reports generated. 12-Hour time format will include the AM and PM modifiers and show the range of time between 1:00 and 12:59, while the 24-Hour time format will show the range of time between 0:00 and 23:59.
