Pro-C Controller
may be selected. This allows the user to 
water on certain days of the week such as 
Monday, Wednesday and Friday or water 
on a repeating day cycle (Interval) such as 
every third day, or odd/even days in any or 
all three of the programs. 
365-day Calendar with Leap 
Year Intelligence…
True odd or even day programming 
In many areas of the United States, 
summer water rationing çs a way of life. 
With its 365-day, leap year intelligent cal-
endar the Pro-C makes programming true 
Odd/Even day watering possible, automat-
ically correcting for 31-day months. Inter-
val or Day of the Week scheduling is pos-
sible as well, to cover any watering day 
restrictions that may be enacted. 
Superior Surge Protection…
All microcircuits are protected from elec-
trical spikes/lightning 
The Pro-C is equipped with electronic 
components called MOV’s (Metal-Oxide 
Varistor). These MOV’s are designed 
to shunt electrical 
surges away from 
microcircuits 
through the 
controller’s 
grounding circuit. 
The Pro-C uses 
these MOV’s to 
protect the controller from minor power 
surges coming in through the primary 
(110/230VAC) imput side and also the 
secondary output side (24VAC).
Note: For 
proper results, 
the ground cir-
cuit must mea-
sure 10 ohms 
or less. 
Global Water Budget/Seasonal 
Adjustment…
Changing run times could not be easier, 
from 10% to 150% 
The water budget/seasonal adjustment set-
ting allows the user to make global 
changes to the run times of each zone 
from 10-150 percent of the original pro-
grammed run time in 10 percent incre-
ments. This feature is perfect for making 
small changes that are necessary as the 
weather changes, without reprogramming 
the entire controller. A unique bar graph 
(thermometer display) in the large LCD 
display lets the programmer know at a 
glance what percent from the original 
settings the controller is operating the sta-
tion run times. 
The ability to 
immediately 
view the recal-
culated run 
times for each 
of the zones is another unique feature built 
into the seasonal adjustment.
Note: The controller should always 
be initially programmed in the seasonal 
adjustment in the 100% position.
