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.

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.
