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 extension cable may be used.

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
