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.

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

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.

WARNING!
4. Connecting the Controller to AC voltage Source
If using an internal transformer, minimal wire diameter must be 0.7 mm. Check with standard
measuring equipment that there is no voltage in the electric circuit. Thread the electric cables
through the small cable protector at the left, connect the two transformer wires to the circuit
b using the standard connector (included).
Affix the connector to the pin positioned on the bottom of the transformer box.

1. General Information
The AC-24 controller has two types of irrigation programming:
 Valve Group irrigation programming
 In epen ent valve irrigation programming
Other options
 Gar en lighting
 Fertilization programming for each valve
Irrigation Programming for Valve Group:
Three programs (A,B,C) can be programme .
For each separate program, irrigation ays must be selecte for all of the valves connecte
to the program group. A starting time is set for the first valve only, an uration of irrigation
for each separate valve. The valves will open sequentially, accor ing to the sequential number
marke on the isplay - when the first valve closes the secon will open, an so forth. Only
one valve will be open at a time. If the programs A, B, an C have been programme to
overlap in irrigation time, Program A will open first, an only after the program has en e
will Program B begin, an , finally, Program C.
Independent Program I
In this program the irrigation sche ule is efine for each in ivi ual valve. First select the
valve an then program: setting irrigation uration, ays of irrigation, or irrigation cycle, an
starting time for the esignate valve.
General Information
To program the controller use the 16-position selector an 4 buttons.
Press Button to move between the fiel s in ifferent positions of the selector.
Press Button to select the ata to be mo ifie (e.g. hour, minute, etc.).
Press Button to increase the value of the selecte ata (e.g. a ing an hour)
Press Button to ecrease the value of the selecte ata (e.g. ecreasing an hour)
