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.

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

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

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.
