The 4-in-1 Controller from Orenco Systems supports numerous electrical configurations and dosing schedules within a single panel. Both simplex and duplex models are available and can be configured in the field for timed or demand dosing. While the control circuit operates on 120-volt power, the pump circuit is dual-rated for 120- or 240-volt power. The panels include a programmable logic controller (PLC) with multiple timing intervals for changing flow conditions and a built-in elapsed time meter and counter. The PLC displays float position and has a float error indicator. Each panel includes a reference chart to assist with troubleshooting during installation and testing, as well as wiring diagrams. 877/488-3594; www.orenco.com/controls.
