The 4-in-1 Controller from Orenco Controls 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 both 120- or 240-volt power, meaning installers and service providers can reduce their panel inventories for new installations and repairs. The panels include a programmable logic unit with multiple timing intervals for changing flow conditions and a built-in elapsed-time meter and counter. It 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. 877/257-8712; www.orencocontrols.com.
