In our application, the water pressure will boost from 30psi to 45 when irrigation is called for.

It is great to have the external pump control option which is included with Pro-16! That's what makes this selective pressure possible to meet demand.

Here however is a special case that has emerged for our application. When the drip irrigation zone(s) are running, we do not need the pressure boost. 30psi as it turns out is perfect. It would in this case be desirable to have the ability to override the auxiliary pump option on a per-zone basis. In other words, we'd want the external pump to come on for all zones with the exception of those controlling drip irrigation.
