LEIT 4000 4, 6 & 8 Station Controllers

The LEIT 4000® is a self-contained, water management irrigation controller that harnesses ambient light (solar) as a power source. The controller's easy-to-navigate features include four independent programs with three start times for each valve, password-protected entry, monthly budgeting up to 200 percent, rain stop up to 99 days with automatic restart, manual run via the program or valve, and status reports including current and past month's information for each valve. A compact design and time-tested photovoltaic module harnesses ambient light energy to power the unit day and night in any kind of weather conditions.

Features

  • No AC power and no AC permit requirements
  • Environmentally friendly; uses clean, renewable solar power
  • Powered by photovoltaic module and internal microelectronic management system which collects light to produce pollution-free electricity that powers the controller day and night in any kind of weather conditions.
  • Operates four, six or eight stations and a master valve or pump start without an AC power hookup, batteries or conventional solar panels (master valve or pump start replaces station eight when required)

  • Non-volatile memory holds programs indefinitely without batteries
  • Programming is easy using a self-guiding menu and four durable sealed buttons
  • Multilingual software (Spanish, Italian, and French)
  • USB port allows for software updates
  • Lightning protection; the controller is fully isolated from electrical ground, offering virtual immunity to ground currents from overhead power lines and/or close proximity lightning strikes
  • Simple-to-install wire connector accommodates standard irrigation wire up to 12 gauge
  • Use with the LEMA 1600HE solenoid actuator, which can be mounted on most brand name valves using one of our seven adapters
  • Withstands the environment and is completely waterproof
  • Can connect rain, moisture or freeze sensors to an individual valve or to the entire system using the SKIT 8821-4 switch-type sensor adapter
  • Four-year manufacturer's warranty
