LEIT-4000

The LEIT 4000® is a self-contained, water management irrigation controller that harnesses ambient light (solar) as a power source, helpful in today's sustainable green solutions. The LEIT 4000 controller easy to navigate features include four independent programs with three start time for each valve, password protection entry, monthly set budget with 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 information for each valve. Compact design and time-tested photo-voltaic module harness ambient light energy to power the unit day and night in any kind of weather conditions.

Features

  • Operates four, six, or eight stations and a master valve or pump start without 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
  • Multi-lingual software (Spanish, Italian, and French)
  • see more
  • Power is provided by an internal, ultra-high efficiency photovoltaic module and microelectronic energy management system fueled by ambient light
  • 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, easy-access wire connector accommodates standard irrigation wire up to 12 gauge
  • Environmentally friendly; uses clean, renewable solar power
  • Assign rain, moisture or freeze sensors to an individual valve or to the entire system using SKIT 8821-4 adapter
