-This is particularly helpful in a use case scenario where a main water supply is used for both irrigation and ie filling a domestic cold water tank at the same time. If the water pressure is only sufficient for either irrigaton or tank filling, this service call allows to `pause` the irrigation whilst a tank is filled, and then `resumes' irrigation without interrupting the time allocated to the sequences or zones thereof.
