ABSTRACT:
The control systems and technique can regulate or control operations of a water treatment system in a primary control mode and, when appropriate, in a secondary or an alternate control mode. The primary control can represent a normal control mode during which the water treatment system is intended to operate. The alternate control mode can represent a second control or mode of operation. The systems can be operated to control or facilitate regulation, monitoring, and performance of one or more operating parameters of one or more water systems between, or to and from, a first mode, a second or alternate mode, and, in some cases, a third or even a fourth control mode. The change in control mode can be triggered by identifying one or more predetermined, pre-selected, and/or programmed conditions.
