Before installation: make sure a filter is installed upstream to the
valve. (See list of additional accessories page 27.)
2. Setting Up the Irrigation Controller
2. 1. Valve and Solenoid Assembly
1. Shut the main irrigation system valve.
2. Before installing the hydraulic valve
[5] in the irrigation system, remove the
solenoid [1] from the valve with a 90°
counter-clockwise turn. Be careful not
to loose the seal (O-ring) [3].
3. Install the hydraulic valve in the
irrigation system, paying attention to
the correct water flow direction, as
indicated by the arrow [4] on the valve
cover.
Figure 2
5. After installing the hydraulic valve [5], assemble the solenoid with a 90°
clockwise turn. Be sure to place the seal (O-ring) [3] in its proper
location.
Note: A small amount of water is expelled from the drainage opening on the
solenoid during valve activation (manual or automatic).

2. 2. Manual-Mechanical Operation
The irrigation valve can be opened
and closed independent of controller
operation. Manual operation is
useful when immediate irrigation is
required, without the delay of
controller programming.
The 3-position valve handle [A] is
located on the solenoid Manual
valve, and functions as follows:
Closed [1], Automatic Operation
[AUTO], Open [2]. Note that the
Open and Closed positions in
2-Way and 3-Way valves are
reversed (see drawing below).
* Figure 3
* 2-Way Valve 3-Way Valve
Important! For automatic irrigation operation, the valve handle must be in
the middle (AUTO) position.
2. 3. Battery Installation
Rotate the battery compartment
cover handle to the 11 o’clock
position to remove the cover. Insert
batteries (see drawing). All
controller display elements will
briefly appear on the display,
followed by the blinking time
“12:00”. The controller is now
ready to be programmed.
Important! Make sure to replace the battery compartment cover with its
handle in the 11 o’clock position to avoid possible cover guide pin
breakage.

2. 4. Installing the Controller In the Irrigation System
If the mounting plate [2] is attached
to the controller, remove it.
1. Insert the mounting coupling [1]
into the mounting plate, aligning
the words “TOP”, which are
stamped on both the coupling,
and the plate (see Fig. 4).
2. Press the mounting plate, with
the mounting coupling inserted,
against the irrigation controller
back.
* The controller mounting plate [2]
can be mounted on a wall using
two screws, in which case
mounting coupling [1] is not
used. The distance between the
controller and the solenoid is
limited by the length of their
connecting cable.

2. 5. Wiring the Solenoid and the Sensor
2. 5. 1. Model DC1S–6051 WP
solenoid wires are permanently connected to the irrigation controller. This
model includes no connection block nor sensor option.
2. 5. 2. Models DC1S–6051 SN, DC4S–6054 SN
1. Remove the bottom cover [1] from the irrigation controller.
2. Connect the solenoid cables to the connection block [2]:
A three-wire cable (white, red and black) emerges from each solenoid.
Connect the White solenoid wire leads (W) to connection “C” on the
connection block.
3. Connect the Red and Black wire leads from each individual solenoid to
its corresponding valve position on the connection block (R=Red wire,
B=Black wire), where each Red and Black wire pair is connected to

the valve number marked. Valve numbers are marked: V1 = first valve,
V2 = second valve, etc.
4. Connect the program lockout sensor (option): Connect the sensor wires
to the connection block positions marked SNSR [3] in any order.
2. 5. 3. Models DC4S–6054 WP, DC1S–6051 WP SN, DC4S–6054 WP
Four of the cables exiting from the controller(1) are the same color and
are marked 1 through 4 . The fifth cable is not marked. The end of each
cable is protected by a plastic covering that must be removed prior to
connection. Cables 1 through 4 should be connected to the four
electrically operated valves (3) and the fifth cable, to the sensor (4).
The controller and its connections are waterproof. In order to maintain the
waterproofing, it is important to ensure the following:
* Do not remove protective coverings from cables that are not connected
to a valve. Exposed cable ends can short-circuit between themselves or
with other conductors.
* The controller cable connections to the valve cables (3) are made using
special waterproof connectors (2) which are included with the product.
See illustration.
1. Cut the plastic protective covering from the controller cables (1) near
the point of their connection. The solenoid cables have three wires:
white, red and black. Strip 3-4 cm of the outer insulation. Do NOT
strip the wires themselves. If the wires' leads are exposed, cut them to
the colored insulation. METAL LEADS SHOULD NOT BE
INSERTED INTO THE WATERPROOF CONNECTOR.

2. Connect each of the wires to the waterproof connector (2).
3. Three wires exit from each of the solenoids: white, red and black.
Connect the white wire of the solenoid to the connector to which you
connected the white wire from the controller. Press the center disc
firmly towards the wires until its surface aligns with the connector's
perimeter. Connect the red and black wires according to the same
principle. Refer to the diagram.
4. Connect the remaining controller cables to the solenoid cables
according to the number of valves in the system. Make sure that the
valve numbers correspond with the numbers on the cables from the
controller.
Sensor connection (optional): The sensor is connected to the additional,
unmarked cable. This cable contains only two wires and should be
connected using a waterproof connection, as described 
Important: Do not program a valve which is not in use or is not
connected using a waterproof connection.

3. Programming the Irrigation Controller
This section details programming steps for a simple irrigation program.
The following section deals with more advanced irrigation controller
applications.
The Computerized Irrigation Controller is programmed with the aid of 4
buttons:
Programming Step Selector - used to select the desired programming
mode
(e.g., clock setting mode)
Parameter Selection Button - used to select the parameter to be
changed (e.g.,
hour, minute, etc.). Only a blinking parameter can be changed.
Data Increment Button (Increase) - raises the value of the selected
parameter
(e.g., when hours selected, from 06:00 to 07:00).
Data Decrement Button (Decrease) - lowers the value of the
selected
parameter (e.g., when hours selected, from 06:00 to 05:00).

the display if an attempt is made
to operate a previously
scheduled valve opening while
the irrigation controller is
suspended.
4. 7. Program Lockout Sensor
(This option is not included in model DC1S–6051 WP)
An advanced feature of the Irrigation Controller enables irrigation
monitoring using a lockout sensor. The lockout sensor contacts remained
closed as long as the pre-defined conditions do not exist. For example, if a
rain sensor is connected to the irrigation controller, irrigation takes place
as long as the sensor remains dry. If rain falls, the sensor prevents all valve
openings.
Each individual valve can be operated in conjunction with the sensor. To
associate the sensor to a particular valve(s), select the desired valve(s) and
activate the sensor (see the explanation below).

Programming Options

SENSOR.
3. Press to activate the sensor in
the irrigation program for the
selected valve.

existence of a defined program
lockout condition) the symbol
blinks on the display. In this
situation, irrigation will not take
place through valves associated
with the sensor.
4.Press to disable the sensor.
The word “OFF” appears on the
