BACKWASH OPTIONS AND ADDITIONAL FEATURES STARK ™ FILTERS
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).
