LEIT® 4000, X and XRC Ambient Light (Solar) Controllers


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, 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.


No AC power and no AC permits requirements for quick and easy installation

Environmentally friendly; uses clean, renewable solar power

Powered by photovoltaic module, and internal microelectronic management system which collect light to producer pollution-free electricity that is stored and used to power the controller day and night in any kind of weather

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)

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

Use with the LEMA 1600HE solenoid actuator, which can be mounted on most brand name valves using one of our seven adapters

Withstand the environment, 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 years manufacturer warranty
