Installation Preparation

1. Adjusting the Irrigation Controller to

the Valves. The irrigation controller is designed

to operate standard electrical valves of up to

24VAC 2.2 W. The valves are not supplied

with the controller.

1. Close the ain water valve.

2. Install valves in the irrigation syste .

A ain electrical valve can be installed at the

entrance to the irrigation syste . The ain

valve will opened auto atically when any valve

is opened, and will close auto atically with

the closing of the last valve.

The ain valve is shown on the display panel

and on the ter inal block by the letter M.

There is no need to progra the ain valve.

2. Mechanical Manual Operation

The irrigation valves ay be opened/closed

unrelated to the operation of the controller.

This ode is useful when irrigation is necessary

i ediately, and there is no ti e for operating

the controller.

The anual operating handle is located under

the solenoid.

1. To open the valve turn the handle counter-

clockwise

2. To close the valve turn the handle

clockwise

* When the electricity is turned on the valve

cannot be closed anually.

* To operate a valve with the controller, the

anually operated handle ust be in a auto

position .

ATTENTION !

Direct water flow according to the

water direction sy bol on the valve.

ATTENTION !

If there is a ain anual valve,

it should be opened anually.

HANDLE

OPEN AUTO

Open the controller door with the attached key .

To get to the connector board, release the lock screws on the left side of the

controller beneath the main cover and open the panel .

Installation and Wiring Instructions

1. Controller Installation

Install the controller on the wall or in a controller cabinet by mounting it with three screws

at the designated holes . Use the included plugs to cover these screws.

Place a 9V battery in the appropriate place .

Installation and Wiring Instructions

2. Adding or Replacing 4 Valve Module

Attention: Modules may be added or replaced only in the A -800248 Model

In order to add or replace a 4 valve module the following procedures must be performed:

1. Turn selector to Testing mode.

2. Disconnect the AC-24V wire.

3. Wait one minute.

4. Remo e battery.

5. With a "cross-head" screwdri er, open

screws on front of module.

6. Add or replace module by pushing it in or

pulling it out.

7. Fasten screws at front of module.

8. Replace battery in position.

9. Reconnect the AC-24V wire.



The number of al es the controller will

now

operate will appear on the LCD display.



The current time must be set.

THE PROGRAMS INSTALLED IN THE CONTROLLER WILL BE STORED

WHEN DISCONNECTED FROM ELECTRICITY (20 YEARS MEMORY!)

Installation and Wiring Instructions

3. Connecting Solenoid Wires

General

Two wires, identical in color and polarity, are connected to each solenoid. One wire (either

one) must connect to the desired valve in module. The second wire must be connected to

point COM in module. The distance between the controller and the valves is usually longer

than the solenoid wires. An e tension cable may be used.

Extension wire information

· The e tension cable transmits only 24 volt.

· The cable must have at least two wires more then the number of required valves, One for

Master valve and one for Common.

· To facilitate wiring it is recommended to use different colored wires.

· Minimum diameter of the cable must be 0.5 mm., if the valves are at a distance of more

then100 meter from the controller, a bigger diameter will be needed. Please consult with

your distributor.

· The cable must be installed properly on the wall with nail clips or underground in a protective

pipe.

· If cable joins are requires, use protective connection bo .

· Connection of the e tension cable to the valves must be in a protective bo . (Not included).

It is recommended to have more connection points in the bo then number of valves.
