when extra watering is needed or if you 
would like to scroll through the stations to 
inspect your system.
Seasonal Adjustment…
Seasonal Adjust is used to make global run 
time changes without re-programming the 
entire controller. This feature is perfect for 
making small changes that are necessary 
as the weather changes without reprogram-
ming the entire controller. For instance, 
hotter times of the year may require a 
bit more water. Seasonal adjust can be 
increased so that the stations will run 
longer than the programmed time. Con-
versely, as Fall approaches, the seasonal 
adjust can be reduced to allow for short 
watering durations.
To use the seasonal adjust, simply press 
the up or down seasonal adjust buttons to 
set the percentage desired. Each bar on the 
graph can be adjusted from 10% to 150% 
of original program. The season adjust can 
be changed at any time regardless of the 
programming dial position. To view the 
new adjusted run time, simply turn the 
rotary dial to the Set Run Times position, 
the displayed run time will be updated 
accordingly as the seasonal adjustment is 
made.
Test Program…
You can activate all stations for a set 
number of minutes.
1.  Hold the   button for 2 seconds.
2.  Station run time will ash in the dis-
play. Use the   or   buttons to select 
the amount of run time from 1 to 15 
minutes.
3.  After a 2 second pause the test pro-
gram will run each station for the set 
run time.
This feature is great for a quick system 
check or to activate valves during winter-
ization.
Advanced Features…
There are three advanced features avail-
able to customize the Pro-C to more com-
plex watering requirements. One of these 
features is “hidden” to make accidentally 
programming them nearly impossible.
1) Set Pump/Master Valve Operation
The default is for all stations to have the 
master valve/pump start circuit ON. The 
master valve/pump start can be set ON or 
OFF by station, regardless of which pro-
gram the station is assigned. This feature 
may be utilized on systems where it is 
desirable for a booster pump not to operate 
with certain zones.
To program pump operation:
1.  Turn the dial to 
SET PUMP 
OPERATION 
position.
2.  Press the   or 
 buttons to 
toggle the master 
valve/pump start 
ON or OFF for 
the specic station.
3.  Press the   button to advance to the 
next station.
4.  Repeat steps 2 and 3 for all necessary 
stations.
2) Programmable Rain Off
This feature permits the user to stop all 
programmed waterings for a designated 
period from 1 to 7 days. At the end of the 
programmable rain off period, the control-
ler will resume normal automatic opera-
tion.
1.  Turn the dial to the SYSTEM OFF 
position.
2.  Press the 
 button and a 1 will be
