The Independent, Preferred Power Irrigation Solution

The LEIT 4000 controller is a programmable, self contained, water management irrigation control system. It can be programmed to control 4 to 8 zones using the 1600HE solenoid with up to 12 independent water schedules per zone. The LEIT 4000 controllers can be installed in any outdoor location.

How much light is needed?

The LEIT controllers are unique to all other water management and irrigation control systems because of their ability to harness ambient light to generate electricity. The electricity is stored in a long life non-battery based super capacitors and used to power the controller. This feature allows the LEIT 4000 system to operate in any area, in any weather conditions, 7 days a week, 24 hours a day. On a normal day with direct sunlight, an average range of 5,000 - 100,000 lux can be measured. The LEIT 4000 controller requires an average of 5,000 lux for normal operation.

Combine the advanced programming capability of the LEIT 4000 controller with the advantages of ambient power and it is obvious why the LEIT families of controllers are the top choice for today's irrigation needs.

The LEIT 4000 is an ambient light powered water-management irrigation controller. It is easy to use with a fast menu base and straightforward programming. Features include independent programs for each valve, monthly budgeting, rain delays and status reports for past and current months. The time-tested photovoltaic module harnesses the energy of ambient light to power the controller in any kind of weather, anywhere in the world.
