FEATURES

  • Removable power cord and receptacles for simple conduit installations.
  • Scheduled feed, which can use three relays for biocides or other chemicals.
  • Two (2) water meter inputs, two (2) drum switch inputs, pH or ORP input, flow switch input, and 4-20 mA output are all standard features.
  • Designed with a single circuit board for better reliability and lower cost.
  • Large open shallow enclosure for easy wiring.
  • Heavy-duty stainless steel domed numeric keypad and illuminated graphical display allow for quick and easy programming.  Steel domed switches improve the tactile sensing and life expectancy of the keypad.
  • LED indicators for power, alarm and relay status.

 


 

BENEFITS

  • Easy to program with the Lakewood plain English, intuitive, and user friendly menu interface.
  • Controller can be removed from a cooling tower and be placed in another type of application when used with the appropriate pH or ORP sensor.
  • Single circuit board design improves reliability.
  • No add-on options.  4-20 mA output and biocide features are standard.
