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, conductivity input, flow switch input, 4-20 mA output,
and remote conductivity input via 4-20 mA are all standard features.
• Designed with a single circuit board for better reliability and lower cost.
• Large open shallow enclosure for easy wiring.
• Ball valve delay feature allows accurate control of motorized ball valves.
• 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 used in boiler, cooling tower, or condensate applications when used with the appropriate
conductivity sensor.
• Single circuit board design improves reliability.
• No add-on options. 4-20 mA output and feed schedule clock features are standard.
