CONTENTS
This unit has been designed to provide reasonable
protection against harmful interference in a residential
install. This equipment uses, generates and can radiate
radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful
interference to radio communications. There is no
guarantee that interference will not occur in any
particular install.
If the equipment does cause harmful interference to
radio or television reception, which can be determined
by turning the equipment off and back on again, the
user is encouraged to try to correct the interference
by (1) reorient or relocate the receiving antenna; (2)
increase the separation between the equipment and
receiver; (3) connect the equipment into an outlet on
a different circuit from the receiver; (4) consult the
dealer or an experienced radio / TV technician for help.
Changes or modifications to this equipment could
void the user’s authority to use the equipment as well
as the warranty.
INTRODUCTION

04
Installation, Programming and Operation Manual
The purpose of a rain sensor is to stop
automatic watering when sufficient
precipitation has been reached.
The rain sensor select button allows the
user to bypass the rain sensor. If a rain
sensor has been installed, and BYPASSED
has been selected, then BYPASSED will
be displayed in the upper left corner
of the LCD.
NOTE When the rain sensor select button
is in the ON position a rain sensor or wire
jumper must be installed in order to run a
program.
Refer to page 19 for further details.
A key feature of the Pro EX 2.0 controller
is its large easy-to-read LCD display.
The display is also backlit when primary
power is being supplied to the controller,
and if any buttons are pushed.
As the program dial is rotated the display
automatically changes. The flashing value
within the display can be increased or
decreased by pressing the DOWN or UP
buttons. To go back or advance to the next
value press the BACK or NEXT buttons.
Because of variations in plant watering
needs the Pro EX 2.0 controller has three
separate programming options A, B and C.
Each program is completely independent
of each other and the controller will
automatically stack programs that overlap.
This allows for all programmed watering
to occur because only one program will
run at a time and in alphabetical order.
Only one start time per program
(A, B or C) is required to operate
all stations with a run time.
The controller automatically and
numerically advances operation
to the next station without the
need or additional start times.
For additional watering, each program can
be set with up to four separate start times.
This allows for greater irrigating efficiency
when all watering can’t be done during a
single operation (cycle and soak).
NOTE: A program must contain at least
one start time, watering day(s) and one
station wit a run time in order to operate.

Installation, Programming and Operation Manual
The Pro EX 2.0 controller can be installed
either indoors or outdoors and must be done
in compliance with local electrical codes.
For the best viewing and ease of programming
we recommend installation at eye level.
The mounting location should have access
to 115VAC or 220VAC electrical power and allow
enough bottom clearance for the installation of
conduit or a “junction” box if required.
Installation should be done at least 15 feet
away from a pump start relay or any high
draw motors, such as air conditioners and
refrigerators.
For ease of installation the enclosure door
and main panel can be removed. 12 inches
of horizontal clearance to the left is necessary
to fully open the hinged door.
1. Making sure the door is unlocked, open
the enclosure door and swing it to the left
until fully open.
2. Using both hands grasp both the top and
bottom portions of the door at the hinge
location.
3. Gently pull either the top or bottom portion
of the door forward until the door releases.
1. Open the front panel by grasping the
finger hold on the top right side of the
front panel. Swing the panel open to
the left.
2. Disconnect the ribbon cable from
the rear of the main panel by gently
pulling the ribbon connector straight
out of the socket.
3. Using both hands grasp both the top
and bottom portions of the main panel
at the hinge location.
4. Gently push the main panel upwards
until the hinge pin is free of the
enclosure socket.

FIELD WIRE ENTRANCESMOUNTING THE CONTROLLER
17
The Pro EX 2.0 controller has a single
keyhole slot on the top / back of the controller.
Three circular mounting holes are located at
the bottom / back of the controller. One of the
three mounting holes is located inside the
115VAC or 220VAC connection box.
Use a pencil to mark the eye level position
on the mounting wall. Or, use the template
provided for easy installation.
Drive an appropriate fastening device for
the type of wall material into the mark for
the keyhole.
Hang the controller on the keyhole slot
making sure the fastener is secured on
the narrow neck area of the keyhole slot.
Making sure the controller is level,
drive an appropriate fastener(s) in
the lower circular hole(s).
The Pro EX 2.0 controller has four
“knockout” plugs available for routing
valve, pump start and sensor wires.
All four are located on the bottom of
the cabinet and sized to 1/2”, 3/4” or
1” PVC male adapters.
In the combination “knockout” plugs,
tap a screwdriver in the groove around
the knockout in several places to remove
the smaller knockout.

RAIN SENSOR INSTALLATION PUMP START RELAY / MASTER VALVE WIRING
19
This section is only for systems that require a
pump start relay or master valve. The controller
does not provide main power for a pump.
Master Valve or Pump Start
Relay wiring terminals
“COM” & “MV/PS” are
located at the lower right
corner of the cabinet.
NOTE: JUMPERS FOR
UNUSED STATIONS
To prevent pump or system
damage w en using a pump
start relay, use a jumper to
connect all unused stations
to t e last station wit a
run time.
Unused station(s) wit out a
jumper could cause pump or
system damage s ould t e
unused station be turned on.
Pump operation wit no flow
(dead- ead), could cause
over-pressurization of t e
system or t e pump to
over eat.
All electrical connections and wiring must
be made according to local building codes.
1. Open the cabinet door.

to the two terminals marked SENSOR
located in the lower right corner of
the cabinet.
NOTE: If a rain sensor as not been
installed in t e Pro EX 2.0 controller, t e
preinstalled jumper wire must remain
installed on t e SENSOR terminals.
For wireless rain sensors needing
an additional power source, use the
VT terminal for 24VAC and use the
COM terminal for the common.
Both are located in the lower left
corner of the cabinet.
