This is the scheduled clock time (HH:MM) on Wednesday at which load bank 1 disconnects as part of the plant's time-of-day load-shed schedule, independent of the voltage- and temperature-based disconnects for that bank, per the description. Because the plant lets each of its three load banks shed on a separate schedule, bank 1 is typically the tier an admin assigns the earliest or most aggressive shed times to, since it is usually wired to the least essential load. Having a separate setpoint for every individual day rather than one blanket daily time lets the site follow a non-uniform weekly shed pattern, such as demand-charge avoidance windows that differ between weekdays and weekends. A value of '22:30' would shed load bank 1 every Wednesday at that time, reconnecting later per the matching reconnect1LoadShedWednesdayOn setpoint.
