CS 400 Commercial Backwash Controller This controller is programmable and controls every aspect of the backwash cycle once initiated. Backwash can be initiated three ways: by an operator with the touch of a button, by a signal from a master controller (such as the AK600), or by a signal from an optional differential pressure switch (CS400- DP). Stored backwash data and history, alarms, and calculated backwash cycle times are also features of the CS400 controller, as are relays for communication with the heater, pump and Acu Drive.
CM200 Manual Backwash Controller This is the simplest Pentair option. No electronics or programming required. Simply turn the knob to backwash each tank in the system.
