3.1 Automatic Irrigation Controller [Light]

Irrigation controllers shall be single, solid-state independent controllers conforming to the following:

The controller shall be powered by an internal, ultra high efﬁciency, photovoltaic module with a microelectronic energy management system fueled by ambient

light. The controller shall have a 2-way radio communication capability using the ISM band 900-928 MHz (LEIT XRC only). The controller shall be protected by a

vandal-resistant, waterproof enclosure fashioned from high impact composite material and made to endure extreme environments. The controller shall function

day and night in any weather condition and in most outdoor locations where no direct sunlight is required. It shall communicate to a micro-power solenoid

actuator via two-way digital control pulses at 5-volts DC. The X and XR controllers require daily exposure to light levels with a minimum of 2,000 lux. This is

equivalent to having sunlight around 8 AM in a shady area. The LEIT XRC shall have a minimum of 15,000 to 20,000 lux, which is equivalent to having a daylight

around 9 AM to 10 AM in a cloudy day.

3.1.1 Controller Features

a. Controller model X shall operate 10, 12, 16, 20, 24, 28-stations and a master valve.

b. Controller model XR upgradable to LEIT Link radio (the controller can be sent back to the factory to be loaded with the hardware for radio, software

already included) shall operate 4, 6, 8, 10, 12, 16, 20, 24, 28-stations and a master valve.

c. Controller model XRC with a 2-way radio shall operate 4, 6, 8, 10, 12, 16, 20, 24, 28 stations and a master valve

d. The controllers shall operate and use a micro-powered solenoid actuator with globe valve or a micro-powered solenoid actuator with the correct adapter

to be mounted on any other valve.

e. Controller shall have bilingual software in English and Spanish.

f. The controller LCD screen shall be activated with a special key powered by a 9-volt alkaline battery to provide access and security to a simple 4-button

programming pad, the LCD shall display all the schedule information.

g. The controller shall have 4 independent programs with 3 start times per station.

h. The controller shall allow custom grouping, allowing the controller to operate any number of stations within a group sequentially (if hydraulic limitations

are not exceeded).

i. Ability to program in one minute increments up to 5 hours and 59 minutes with separate setting for hours and minutes.

j. The LEIT XRC controller shall have a 2-way radio capability using the ISM band 900-928 MHz to communicate with a LEIT Link radio from a distance of up

to 800' line of sight.

k. A programmable watering calendar with a choice of a 1-39 day interval, odd/even days or any day(s) of the week.

l. A feature that shall include password protection for added security.

m. Rain stop from 1-99 days with automatic restart.

n. A 12 month budget adjustment from 10% to 200% in 10% increments.

o. A manual feature that allows a single desired station to cycle start for any preset, preferred duration.

p. The controller shall have the option to operate automatic, semi-automatic and manual cycle via the controller.

q. The controller shall have a monthly off feature that allows turning off any month of the year.

r. Status and history reports to review controller functions and the amount of watering time applied during current and previous month.

s. The controller shall have the option to assign any switch type rain sensor, moisture sensor or freeze sensor to an individual valve or to the entire system

using a SKIT adapter. (Rain sensor is recommended.)

t. The controller shall activate the micro-powered solenoid actuator LEMA 1600HE to a distance of up to 7500' (2270m) using NFPA 70 copper conductor

12-gauge (1.6 mm) irrigation wire type UF.

u. The controller shall be capable of operating pump start relay or a master valve using a RKIT 8810S relay interface module.

v. The XRC controller shall use a 2-way radio remote handset that can operate in the ISM band 900-928 MHz. To use a 2-way radio communication in the

ISM band 900-928 MHz, the controller shall use a LEIT Link 2-way Radio Remote Handset

w. The controller shall have lightning protection to fully isolate the controller from electrical ground, and offer virtual immunity to ground currents from

overhead power lines and/or close proximity lightning strikes.

x. The controller shall have a full 3-year repair or replacement warranty, prorated from in-service date.

y. The controller shall have a lifetime lightning warranty.

z. The controller and its components shall be manufactured by DIG Corporation, Vista, CA.

3.1.2 Controller Components Descriptions

a. Mounting column

a1. The controller shall be mounted on a galvanized mounting column with a length of about 35" short or 50" long with a curved sweep at the bottom to

permit ease of wire pull.

b. Micro-powered solenoid actuator

b1. Micro-powered solenoid actuator with globe valve

The remote control valve, with a micro-powered solenoid actuator shall be a globe type, normally closed, using bipolar pulse. The valve shall be

pressure rated up to 150 PSI and have balanced opening and closing. The valve(s) body size shall have a 3/4" up to 2" FNPT inlet and outlet,

constructed of weather resistant, high impact glass reinforced nylon and stainless steel spring (303). The valve(s) one piece diaphragm shall have
