ESP-LX Plus and
ESP-LXi Plus SERIES
6, 8, 12, 16, 24 Stations

Primary Application

Indoor/Outdoor (LX+) or indoor (LXi+) hybrid controller for light commercial and residential use. Advanced, easy-to-use features designed to meet diverse irrigation requirements, including low volume drip applications.

Features

• ESP: Extra-Simple-Programming with self-prompting large alphanumeric LCD display makes this controller easy to program, read and understand.
• Four independent programs (A-, B-, C-, and D-drip), with six start times each, allow mixed irrigation applications in a single controller.
• 365-day calendar with leap year intelligence for one-time date and time setting.
• Four cycle modes (CUSTOM, CYCLICAL, ODD, or EVEN) selectable for each program for maximum flexibility.
• Non-volatile program memory maintains user's program during a power outage independent of the battery backup.
• Event-Day-Off option to set any day of the month as a non-watering day for all programs accommodates special occasions and special water ordinances.
• Programmable Delay-Between-Stations (from 1 sec. to 9 hours) provides time for water well recovery or time for slow-closing valves to turn off completely.
• Start time stacking prevents hydraulic overload.
• Variable test program for system operational testing.
• Removable, battery-programmable panel for the convenience of both programming instruction and programming prior to installation.
• Water budgeting by program from 0 to 300% in 1% increments makes seasonal adjustments quick and easy.
• Programmable rain delay enables system to stay off for specified period with an auto-restart.
• Sensor inputs and override switch with LED indicate when irrigation is suspended.
• Master valve/pump start circuit, programmable by station, for optimal irrigation control.
• D-drip program can run simultaneously with program A, B or C to maximize hydraulic capacity and minimize watering time.
• Diagnostic circuit breaker and LED fault indicator identify electrical shorts, skip shorted stations, and continue irrigation cycle.
• Battery recharging circuit maintains fully charged Ni-MH backup battery (included) to keep current time and date during a power outage.
• Surge protection, backed by a 3-year lightning warranty, makes the controller reliable and robust under extreme field conditions.
• Heavy-duty 1.25A external, plug-in style transformer on the ESP-LXi+ indoor version provides convenient installation.
• Includes easy-to-mount, heavy-duty plastic cabinet with key-lockable door and swing-out quick release face panel, as well as all internal wiring (no junction box needed), for clean-looking, professional installation.
• Special Fuse Circuitry detects and displays when a fuse has blown.
• UL Listed; CSA, CE approved
