BACKWASH OPTIONS AND ADDITIONAL FEATURES

CM200 Manual Backwash Controller (Backwash Option "M")

This is the simplest Pentair option. No electronics or programming required;

simply turn the knob to backwash each tank in the system.

CS 400 Semi-Auto Backwash Controller (Backwash Option "S")

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.

CA 100 Automatic Backwash Controller (Backwash Option "A")

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).
