This attribute can be defined as [[time sequence (Water Overlay)|values over time]], using an array of values defining {{time sequence interpolated}}. This allows users to more dynamically define the target water level this pump maintains.

Icon Key Unit Range Description Default value
Waterwizard icon lower threshold.png LOWER_THRESHOLD m + datum The threshold of the lower end-point of the pump. Water flows from the lower end-point to the higher end-point until the water level at the lower end-point has reached the threshold. If not selected, the Lower Threshold will be ignored as a mechanic. None

This attribute can be defined as values over time, using an array of values defining start-time. This allows users to more dynamically define the target water level this pump maintains.

Notes

  • When the PUMP_Q of the pump is positive, the pump will not pump if the water level is lower than or equal to the lower threshold. If the PUMP_Q is negative, the pump will not pump if the water level is higher than or equal to the lower threshold.
  • When using a dynamic LOWER_THRESHOLD, a maximum of 10.000 values (5.000 pairs) can be defined.
