||The threshold of the higher end-point of the pump. Water flows from the lower end-point to the higher end-point until the water level at the higher end-point has reached the threshold. If not selected, the Upper Threshold will be ignored as a mechanic.
This attribute can be defined as values over time, using an array of values defining interpolation-time. This allows users to more dynamically define the target water level this pump maintains.
- When the PUMP_Q of the pump is positive, the pump will not pump if the water level is higher than or equal to the upper threshold. If the PUMP_Q is negative, the pump will not pump if the water level is lower than or equal to the upper threshold.
