MULTIPLE PUMP OR ZONE
As with the simplex and duplex timer based control systems, the multiplex systems are ideal for managing and monitoring daily flow of wastewater, but are intended for use in larger commercial and industrial systems. The multiplex systems contain many of the same features found in the smaller systems but are typically micro-processor controlled to allow for a greater amount of flexibility. Any combination of pumps and/or zone valves may be left out of service, at the flip of a switch, without affecting the sequence. Pump and/or zone valve fail circuits allow for easy detection and alarm of failed equipment or lines.
