tank in the system.

CA 100 Fully Automatic Backwash Controller

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.

This is a comprehensive backwash controller and can be readily reprogrammed to initiate

backwash automatically based on differential pressure (integral pressure transducers

are standard), time (internal seven-day clock with battery back-up is standard), flow (with

optional flow sensor), or any combination of the above. The controller has real-time display

of operation mode, filter flow rate, and water temperature (with optional temperature probe).

Also, includes Energy Saver Mode for simple On/Off pump scheduling and various interlocks

and relays to communicate with other equipment (pump, heater, Acu Drive).
