A. Automatic Irrigation Controller [LEIT] Description:
The LEIT-2 is a wireless irrigation control system that combines controller and handset. The LEIT-2 controller is a 2-station
ambient light powered, wireless controller that can be programmed using the LEIT RC2 handset. The LEIT RC2 remote control
handset communicates with up to 99 LEIT-2 controllers, or 198 valves, from a distance of up to 350 feet line of sight. The
RC2 remote handset has a large LCD display with intuitive icon-based software that is used to communicate with the LEIT-2
controllers. All controller operations are performed using the RC2 remote handset. After installation, no further visits to the
actual controller are required under normal conditions.
B. Automatic Irrigation Controller [LEIT] Specifications:
The LEIT-2 irrigation controller shall be a single, solid-state independent wireless controller. The controller shall be a wireless
controller powered by internal photovoltaic module with a microelectronic energy management system fueled by ambient
light.
The LEIT-2 controller shall be programmed via the LEIT RC2 remote control handset from a distance of up to 350 feet line of
sight. Up to 99 controllers can be programmed using 1 handset when client ID and controller ID’s are assigned.
The LEIT-2 controller shall be protected by a vandal-resistant, waterproof housing, fashioned from super tough plastic material
and made to endure extreme environments. The controller shall function day and night in any weather and in most outdoor
locations. No direct sunlight is required.
The LEIT-2 controller shall have a mounting option for a valve box lead or a column mounting. The controller shall operate
a DC solenoid via two-way digital control pulses with a daily exposure to light levels of 3,000 to 100,000 Lux. All controller
operations can be reviewed or changed using the handset.
C. Automatic Irrigation Controller [LEIT] Construction:
The LEIT automatic irrigation controller’s lens shall be made of GE Super-tough LEXAN© Polycarbonate resin with UV
resistance to protect the photovoltaic module from moisture, dust, chemicals and impact damage. The LEIT waterproof
housing is fashioned from tough material endures extreme hot, cold, wet or dry weather conditions. The lens shall be coated
with an additional clear layer of UV protection preventing discoloration and stress-cracking of the lens. The LEIT controller
shall be mounted securely to a valve box using one of three color coded mounting domes or rugged galvanized steel mounting
column provided by the manufacturer.
D. Automatic Irrigation Controller [LEIT] Operation:
The LEIT automatic irrigation controllers shall operate 1 or 2 stations and without AC power hookup, batteries or conventional
solar panels. The LEIT controller’s power shall be provided by an internal, ultrahigh efficiency photovoltaic module and
microelectronic energy management system fueled by ambient light. The LEIT controller shall require the use of a LEIT
Handset to communicate with the LEIT controller and change or modify the controller programming. The LEIT controller shall
be programmed using the LEIT Handset with a self-guiding menu and five durable sealed buttons for navigation. Entering the
controller a password or ID shall be used to eliminate potential user error. The password can be changed at any time during
communication with the controller. The LEIT shall have a non-volatile memory holding programs indefinitely without batteries
or AC power. The LEIT shall operate in a temperature range of 14-140°F (–10-60°C).
