DECLARATION OF CONFORMITY 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 modications to this equipment could void the user’s
authority to use the equipment as well as the warranty.
INTRODUCTION
The PRO EX 2.0 WiFi Enabled Controller is available as indoor or
outdoor models, with both modules utilizing a WiFi enabled Hub.
The unit consists of a master valve/pump start, test, common,
sensor terminals and one factory installed module which will
operate four electric valves. The controller is expandable by
installing separately purchased four station modules which are
installed internally in the controller.
In addition, the WiFi enabled controller includes a separated WiFi
Hub (Photo), RF Module (Installed in Controller) and optional Long-
Range Antenna.

NOTE: Pressing any button will momentarily
display the current “Revision Number,”
“K-RAIN” or full display screen.
1. Turn the dial to “AUTO”
When the dial is in the “AUTO” position
the controller will run in automatic mode.
The display will show the selected program,
the day of the week and the time of day.
The controller will turn on automatically to
meet ANY programmed water schedules.
If the controller has been turned OFF via iOS,
Android or web browser, the display will
show BYPASS WiFi. Simply turn the dial to
OFF then back to AUTO to make the controller
run in AUTO mode.
The PRO EX 2.0 controller has three
separate programs, A, B and C.
Multiple programs allow valves

RAIN SENSOR SELECT BUTTON PROGRAMMING
The purpose of a rain sensor is to stop
automatic watering when sufcient
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, or if the
program or controller is being accessed
via smartphone, tablet or web browser.
As the program dial is rotated the display
automatically changes. The ashing 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 for additional start times.
For additional watering, each program
can be set with up to four separate
start times. This allows for greater
irrigating efciency 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 with a run time in order to operate.

SEASONAL ADJUST STATION DELAY/OVERLAP PUMP ON / OFF
SPECIAL FEATURES
The seasonal adjust feature allows the user to
increase or decrease station run times globally,
for all stations, without re-programming each
individual station. Run times can be reduced to
as little as 10% or as high as 200%.
This feature is used to decrease or increase
watering times during seasonal temperature
changes. The seasonal adjust % is calculated
on the programmed run time for each station.
For example: if a station is programmed to run
10 minutes, and the seasonal adjust is adjusted
downward 80%, the station will now run for
8 minutes. Conversely, if you set the adjustment
upwards to 120%, the same station will now
run for 12 minutes.
1. Turn the dial to SPECIAL FEATURES. Display
will show “SEASONAL ADJUST % 100.”
2. Press UP or DOWN buttons to set the
percentage in 10 degree increments.
3. Return the dial to AUTO.

via smartphone, tablet or browser.
The station delay / overlap feature allows the user to
insert a global time delay or overlap between the end
of any station’s watering cycle & the beginning of the
next station’s watering cycle.
Station delay is used in systems that have slow
closing valves or pump systems operating with
a slow recovery time.
Station overlap is used to reduce hydraulic
overload (water hammer).
1. Turn the dial to SPECIAL FEATURES. Display
show “SEASONAL ADJUST % 100.”
2. Press NEXT button to enter the delay/overlap
feature. The display will show “DELAY 0:00.”

5. Return the dial to AUTO.
NOTE: This feature is not able to be set
remotely via smartphone, tablet or browser.
The PUMP ON/OFF feature allows the user
to enable or disable the MV/PS terminal for
each individual station.
The ON/OFF feature is used in irrigation
systems where it is desirable for a pump to
operate or not operate for a specic station(s).
1. Turn dial to SPECIAL FEATURES. Display
will show “SEASONAL ADJUST % 100.”
2. Press NEXT button until “PUMP” is

SET OPTIONAL HI/LO FLOW LIMITS
Using the HI/LO ow limits feature allows you to ne
tune your ow sensing. Setting these limits helps in
diagnosing or pinpointing where you may have a wa-
ter management issue, a line break, a broken head or
even a clogged line, for example. You can either keep
them very general and set the limits by program or be
very specic and set the limits by individual zone.

1. Turn the dial to SPECIAL FEATURES. Display
will show ”SEASONAL ADJUST % 100.
2. Press the NEXT or BACK button until
SET MTR is displayed.
3. Push the BACK and NEXT buttons at the
same time to get to the HI/LO limit settings.

toggle between OFF and ON using the
UP or DOWN button. Press NEXT.
This default is set to “BY PROGRAM”,
but you can toggle with the UP or DOWN
button to switch to BY ZONE.
