Pro-C Controller
Start Time Stacking…
Prevent hydraulic overload 
Preventing hydraulic overload is very 
important when designing irrigation sys-
tems, especially residential ones. All elec-
tronic controllers such as the Pro-C allow 
the user to input start times into the pro-
grams that could cause the controller to 
overlap station run times. This occurs 
when the station run times add up to 
more minutes than the amount of time pro-
grammed between the start times. In the 
Pro-C, the start times will stack and not 
begin to actually water until the previous 
start time has completed its run through of 
all zones programmed. This great feature 
will eliminate the possibility of more than 
one zone operating at a time, causing the 
system to perform poorly when water pres-
sure and ow are minimal. 
Multi-language Capability…
User friendly in all parts of the world 
The Pro-C line is available as a multi-
language controller family. Separate cus-
tomization kits are available in Spanish 
(INT-451), French (INT-452), Italian 
(INT-453), and German (INT-454). These 
kits include an owner’s operation manual, 
door instruction card and a faceplate 
overlay that replaces the English version 
included with the controller. 
PC Programming Option…

Are you looking for 
ways to reduce eld 
time at the controller? 
Write an irrigation 
schedule in your ofce 
on your PC using SRP 
software version 2.0 or 
greater. Download your 
program into the Hunter SRP Programmer 
tool. Take the SRP tool to the controller, 
attach it to the SmartPort
®
 connector (fur-
nished with controller) and upload the pro-
gram into the controller. It takes less than a 
minute! The SRP Programmer will accept 
two independent programs for two differ-
ent applications. 
Operate Three 7.2 VA Solenoids 
Simultaneously…
Able to accommodate larger water 
volume systems 
The Pro-C has the power capacity to oper-
ate up to three 7.2 VA solenoids simulta-
neously. There are times when the need 
to operate two valve solenoids off of one 
station terminal (and one solenoid on the 
pump start/MV terminal) is required. This 
type of operation may be the result of 
reduced watering windows, a retrot with 
a city water system switching over to a 
water well system, or low volume (drip) 
zones added to regular zones. Whatever the 
reason may be, the Pro-C can handle it.
Assign Zones to Any or All Programs…
Complete versatility for any watering 
requirement
Any station can be assigned to any or all 
programs in the Pro-C, making the Pro-C 
a truly versatile controller. This feature 
allows zones to have more than one water-
ing schedule if required by the landscape. 
Automated Chronological Ordering of 
Start Times…
No more “phantom” starts!
When more than one start time is entered 
into a program, in any order of sequence, 
the Pro-C automatically shifts the start 
times in ascending order from the earliest 
start time to the latest start time. The Pro-C 
will also shift or “rubber band” the start
