LEIT-2ET Control System
DIG’s LEIT-2ET weather-based wireless irrigation control system utilizes evapotranspiration (ET) data and site information to adjust daily irrigation programming according to real-time weather information provided locally. It is programmed to monitor, control and adjust irrigation schedules for each zone through evapotranspiration (ETo) data transmitted hourly and daily from a local weather station and site information received from the LEIT RC2 ET handset. Site information provided by the LEIT RC2 ET handset combined with the weather station data is used by the controller to calculate the daily local microclimate evapotranspiration (ETc) and automatically adjust the daily irrigation schedule.
Controller Features
- Environmentally friendly-RoHS compliant components
- Waterproof, IP68 compliance
- Weather-resistant. Built from tough, rugged material to withstand harsh environmental conditions
- Efficient photovoltaic module (PVM) energized by an ambient light (solar), high-efficiency microelectronic management system
- Operates up to two stations and a rain sensor
- Compatible with the Unimax S-305DC solenoid
- Unique Client ID identity code for controller and handset
- Information transmitted from the weather station sensors or LEIT RC2 ET 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
- Three mounting configurations including green, tan and purple valve box mounts with direct-to-valve clip mounting and column mounting with 25″ (63 cm) or 50″ (127 cm) mounting columns
- Three-year manufacturer’s warranty
Handset Features
- Simple, icon-based programming
- Reviews status information, updates ET information, checks history reports, adjusts budgeting, programs rain delays and performs manual run
- run or tests
- Environmentally friendly – RoHS compliant components
Weather Station Features
- Weather data transmitted is stored by the controllers and can be reviewed by the LEIT RC2 ET handsets
- Self-emptying tipping bucket rain gauge reads rainfall in 0.01″ (.254 mm international) increments
- The LEIT WWS and WWSE weather stations advise LEIT ET controllers to completely stop irrigation in extreme weather conditions
