MOUNTING THE CONTROLLER TO WALL

NOTE: The indoor EC is not water or weather resistant,

and must be installed indoors or in a protected area.

1. Secure one 25 mm screw (A) into the wall. Note: Install screw

anchors if attaching to drywall or masonry wall.

2. Slide the keyhole (B) on top of the controller over the screw.

3. Secure controller in place by installing screws in the holes (C)

below the terminal strip area.

Do not plug transformer into power source until the con-

troller is mounted and all valves have been connected.

Installing the Conduit Cover

(For indoor controller installations)

The conduit cover is provided to cover the field wires as they exit the

conduit into the bottom of the controller. The conduit cover can be

used with ½" or ¾" diameter conduit.

To install the Conduit Cover:

1. Remove the lower access panel

on the EC.

2. Slide the conduit cover on the

bottom edge of the controller.

3. Bring the conduit and field wires to the bottom

of the controller. Make sure that there is a

sufficient length of conduit so it enters the

conduit cover. There are two small notches on

the left side of the cover to route the 24VAC

wires from the external transformer, or wires

from the sensor and P/MV (if applicable).

4. Secure the conduit cover to the wall with the

screws and anchors provided.

5. Replace the lower access panel on the EC.

CONNECTING VALVES AND TRANSFORMER

1. Route control wires between valve location and controller. Typi-

cally it is recommended that at least 1 mm diameter conductor

cable be used.

2. At the valves, attach the common wire to either solenoid wire of

the valve. This is most commonly a white colored wire. Attach a

separate control wire to the remaining solenoid wire and make a

note of the color corresponding to each valve and the watering

station it controls.

3. Secure the wires with a waterproof wire connector to protect the

connection.

4. Secure the white valve common wire to the screw on the terminal

marked C. Connect the color-coded wires from the valves to their

appropriate station numbers and tighten the screws.

Conduit

Cover

5. Indoor model: route transformer cable through the left side of the

controller and connect the wires to the two screws marked AC.

CONNECTING THE BATTERY

Connect a 9-volt alkaline battery (not

included) to the battery wire clip located in

the lower left-hand side of the controller.

The battery will allow you to program the

controller without AC power. However, the

battery will not be able to activate any of

the station valves. AC power must resume

before watering will continue.

CONNECTING A MASTER VALVE

NOTE: Complete this section only if you have a master valve

installed. A master valve is a “normally closed” valve

installed at the supply point of the main line that opens only

when the controller initiates a watering program.

1. At the Master Valve, attach the common wire to either solenoid

wire of the valve. Attach a separate control wire to the remaining

solenoid wire.

2. The common wire will still go to the screw slot marked C. The ad-

ditional wire coming from the master valve will go in the screw slot

marked P.

Outdoor model: transformer wires are already connected to the

AC slots so all that is required is to connect primary power to the

junction box from a power source.

E – High Voltage Wiring Compartment (Outdoor Model only)

NOTE: Outdoor model is water and weather resistant.

Connecting the outdoor EC to the primary power should

only be done by a licensed electrician following all

local codes. Improper installation could result in shock

or fire hazard.

Route AC power cable and conduit through the ½" (13 mm) conduit

opening on the the left side of the bottom of the cabinet and connect

one wire to each of the two wires inside the junction box. Do not

connect high voltage wires to the AC terminals inside the controller.

Wire nuts are provided to make these wire connections. Note: For -E

models, connect the wires to the AC terminal strip located inside the

junction box.

Do not plug transformer into power source until the con-

troller is mounted and all valves have been connected.

Pump Start Relay

4.5 Meters Minimum (15')

To Pump

CONNECTING A PUMP START RELAY

NOTE: Complete this section only if you have a pump

start relay installed. A pump start relay is a device that

uses a signal from the controller to actuate a separate

electrical circuit to energize a pump to provide water to

your system.

The controller should be mounted at least 4.5 m away from both the

pump start relay and the pump.

1. Route a wire pair from the pump relay into the controller housing.

2. Connect common wire to the screw slot C (Common) and the

remaining wire from the pump relay to the P screw slot.

Relay holding current draw must not exceed .28 amps. Do not connect

controller directly to pump—damage to controller can result.

CONNECTING A WEATHER SENSOR

A Hunter weather sensor or other type of micro-switch weather sensor

can be connected to the EC. The purpose of this sensor is to stop

watering when weather conditions dictate.

1. Remove the jumper that is attached across the SEN terminals of

the controller.

2. Connect one wire to the SEN terminal and one to the other

SEN terminal.

NOTE: If the rain sensor is interrupting irrigation you can

bypass it by using any of the following: MANUAL-ONE

STATION, MANUAL-ALL STATIONS, or ONE TOUCH START

AND ADVANCE. See section “Rain Sensor Bypass” for

more information.

POWER FAILURES

Due to the possibility of power failures, the controller has non-volatile

memory. Programmed information will never be lost. The controller

will keep the correct time for up to 1 month without power. Normal

watering will resume when AC power is restored.

PROGRAMMING THE CONTROLLER

The EC display shows time and day when the controller is idle. The

display changes when the dial is rotated to indicate the specific

programming information to enter. When programming, the flashing

portion of the display can be changed by pressing the or

buttons. To change something that is not flashing, press the button

until the desired field is flashing.

Three programs A, B and C each with the ability to have four daily

start times, permit plants with different watering requirements to be

separated on different day schedules.

NOTE: A basic programming rule is that whatever symbol

or character is flashing will be the item programmed.

For instance, if the hour is flashing when setting the

time, the hour can be changed or programmed. For illus-

tration purposes, flashing characters are in GRAY type.

Setting the Date and Time

1. Turn the dial to the CURRENT TIME/DAY

position.

2. Hours will be flashing. Press the or

button to change the hour shown on the

display. Press the to proceed to setting

the minutes.

3. Minutes will be flashing. Use the or

button to change the minutes shown on the

display. Press the to proceed to select

AM, PM, or 24 hour time.

4. The time will be displayed, and an arrow will

be flashing on AM. Press the and but-

tons to select AM, PM, or 24 hour. Press the

to proceed to setting the day of the week.

5. The number for day 1 will be flashing. Press

the and to select the day of the week

corresponding to the day.

The time and day have now been set. You can turn the dial to

AUTOMATIC to display the current time.

Setting Watering Start Times

1. Turn the dial to the START TIMES position.

2. The factory preset is set on program A. If

necessary, you can select program B or C

by pressing the button.

3. Use the or button to change the start

time. (The start times advance in

15 minute increments).

4. Press the button to select the next start time, or press for

the next program.

NOTE: One start time will activate all stations sequen-

tially in that program. This eliminates the need to

enter each station’s start time. Multiple start times in a

program can be used for separate morning, afternoon, or

evening watering cycles.

Eliminating a Program Start Time

With the dial set to the SET WATERING START

TIMES position, push the or button until

you reach 12:00 am (Midnight). From here push

the button once to reach the OFF position.
