Overview

Simplex demand control panels operate single pumps for residential and light commercial dose-on-demand systems. Each unit operates on either one differential float switch or two narrow-angle float switches for pump control plus one narrow-angle float switch for alarm indication. Simplex controls are typically used when economy is desired, and immediate backup is not necessary. Sufficient storage above the alarm float is recommended to allow time for system repair.
