Several options are available to modify the value returned by your rule or to influence its applicability. These rule modifiers are located below the thumbnail plot, at the bottom right of the rule editor. The rule modifiers are:
Period Average Limit — to meet the flow limit over a period of time rather than timestep by timestep
Hour of Day Multiplier — modify the flow limit hour by hour
Day of Week Multiplier — modify the flow limit for each day of the week
Rising/Falling Condition — apply the rule only if the current conditions match the rising or falling condition specification.
