LEIT-2ET Control System

LEIT-2ET system is designed to monitor, control and adjust irrigation schedules for each zone through the weather data that is received by the on-site weather station . The LEIT-2ET epitomizes a true wireless control system. The system operates by using ambient light (solar) power that charges lead-free super capacitors, not batteries, making it one of the most environmentally friendly controllers on the market.

    Controller Features
  • Environmentally friendly- RoHS compliant components
  • Waterproof, IP68 compliance
  • Weather-resistant. Built from tough,

  • rugged material to withstand harsh
  • environmental conditions
  • PVM and microelectronic
  • management system fueled via ambient (solar) light. Efficient photovoltaic module (PVM) energized
  • by ambient light (solar) powers a high efficiency microelectronic management system
  • Operates up to 2 stations and a rain sensor
  • Compatible with Unimax S-305DC solenoids
  • Unique Client ID identity code for controller and handset
  • Information transmitted from the weather station sensors or LEIT RC2ET handset is used to override or adjust daily scheduled irrigation programs
  • Utilizes ISM band radio frequency band (915MHz NA, 866.5MHz Hong Kong, 868MHz International) CE, IC, FCC certified, Australia and Hong Kong compliant
  • Non-volatile memory retains program and controller integrity
  • Program stacking feature prevents hydraulic overload
  • Custom station grouping allows controller to operate the two stations simultaneously if hydraulic limitations are not exceeded
  • Available with 18" (45 cm) color-coded 16 gauge wires for each valve and rain sensor
  • 3 mounting configurations including green, tan and purple valve box mounts, direct-to-valve clip mounting and column mounting with 25" (63 cm) or 50" (127 cm) mounting columns
  • 3 year manufacturer warranty
    Handset Features
  • Simple, icon-based programming
  • Programs the LEIT-2ET controller,
  • reviews status information, updates ET information, checks history reports, adjusts budgeting, programs rain delays and performs manual
