EZ Series® Simplex

Single Phase Simplex Demand / Timed Dose

EZ Series® control panels combine circuit board technology and easy operation for on-site installations.

The EZ Series® Simplex control panel is designed to control one 120/208/240V single phase pump in water and sewage installations. It features a digital display on the inside of the front cover for programming and system monitoring. The panel configuration can be easily converted in the field to either a timed dose or demand dose application.

The optional mounting post features a removable access cover to allow for easier wiring. The post can be mounted in the ground, directly over a 4x4, or conduit.
