LEIT 1 with Inline Valve

DIG’s LEIT 1™ ILV-XXX single-station solar powered controller with a DC latching solenoid is available on a 3/4” to 2” inline globe valve. Powered by a photovoltaic module with a patented microelectronic energy management system, the LEIT 1™ requires no batteries or direct sunlight to operate, and it is installed above grade in any location where there is ambient light. Distinguished among the LEIT-1™ features are 20 preset monthly historical Evapotranspiration (ET) programs for spray heads and drip irrigation with an editing feature that can be used as part of the controller programming.

Features:

  • No direct sunlight required
  • Environmentally friendly with no backup battery or AC power necessary; uses clean, renewable solar power
  • Power is provided by an internal, ultra-high efficiency photovoltaic module and microelectronic energy management system fueled by ambient light
  • Simple, icon-based intuitive programming
  • Simple Smart™ historical ET feature automatically adjusts irrigation schedules monthly
  • Power level meter indicates the approximate charge (energy available)
