Installing Station Modules
The Pro- C controller is supplie d with a factory-i nstalled base
module fo r up to 4 stations. Additi onal modules may be a dded
in incremen ts of 3 stations (PC M-300) or a singl e 9-station
(PCM-90 0) to expand the controll er’s station capabil ity to 16
stations. Additional modules are sold separately.
The Pro- C utilizes automatic mo dule recognition fi rmware to
identif y when PCM modul es are installed or rem oved from the
controller. This feat ure will recognize the cor rect number of
station s without having to rese t or cycle power to the cont roller.
Installing PCM Modules
The Pro- C controller is designe d with a simple to use “Power
Lock” featur e that assures that the mo dules are energized a nd

Connecting a Hunter “Clik” Weather Sensor (continued)
Testing the Weather Sensor
The Pro-C provides simplified testing of a rain sensor when
the sensor is wired into the sensor circuit. You can manually
test proper operation of the rain sensor by using the One
Touch Manual Start (see page 26). During the Manual cycle,
pressing the test button on the “Clik-type” sensor
(eg. Mini-Clik®) will interrupt watering.
NOTE
The Manua l single station fu nction ignores a ny attached sens or
and will allo w watering to occur.
Manually Bypassing the Weather Sensor
If the rain sensor is interrupting irrigation,
you can bypass it by using the bypass switch
on the front of the controller.
Slide the switch to the Bypass position
to disable the rain sensor from the system to
allow for controller operation. You can also bypass the weather
sensor for manual operation by using the Manual function.
The Bypass switch does not affect the Seasonal Adjust update
when using the Solar Sync sensor.

Connecting to the Hunter Solar Sync
®
The Solar Sync is a sensor system that, when connected
to Hunter Pro-C, will automatically adjust your controller
watering based upon changes in local climate conditions.
The Solar Sync utilizes a solar and temperature sensor
to measure on-site weather conditions used to determine
evapotranspiration (ET), or the rate at which plants and turf
use water. In addition, the Solar Sync sensor includes
a Hunter Rain-Clik and Freeze-Clik sensor that will shut down
your irrigation system when it rains and/or during freezing
conditions.
The controller will automatically increase or decrease watering
run times based on changes in weather. The result is a new
water-efficient irrigation product that promotes water
conservation and healthier plants. You simply program your
controller like you normally would, and the Solar Sync takes
over from there, eliminating the need to manually adjust your
watering schedule.
For installation and programming instructions of your Hunter
Solar Sync, please refer to the Solar Sync owner’s manual.

Cycle and Soak
The Cycle and Soak feature allows you to split a station’s
run time into more usable, shorter watering durations. This
feature is useful when applying water to slopes and tight soils
because it automatically applies water more slowly, helping to
prevent runoff from occurring. You should enter the Cycle time
as a fraction of the station’s watering time, and the Soak time
as the minimum number of minutes required before watering
can occur again for the next Cycle. The total number of cycles
is determined by taking the total programmed station run
time and dividing it by the Cycle time.
Accessing the Cycle and Soak Menu:
The Cycle and Soak feature is accessed by placing the dial
in the RUN position, pressing and holding the j button for
3 seconds; while holding the j button rotate the dial to the
RUN TIME dial position, then release the button.
Example of Cycle screen upon
entering
Example of Cycle screen with

Setting the Cycle Time:
Initially Station 1 will be displayed. To access other stations,
press the h or i button.
Once the desired station is displayed, use the j or k button
to increase or decrease the Cycle time. The user can set the
time from 1 minute to 4 hours in 1 minute increments or to OFF
if no Cycle is desired.
NOTE
Before 1 hour, only minutes are displayed (e.g. 36). At 1 hour
or above, the display will change to include the hour digit (e.g.
1:13 and 4:00).
If a station’s Run Time is less than or equal to the Cycle time,
then no Cycle will be applied.

menu then Station 2 will be displayed upon pressing the
n b utton).
NOTE
The Soak menu cannot be accessed without a programmed
Cycle time.
Setting the Soak Time:
To access the other stations, press the h or i button.
NOTE
When changing the stations, if a station without a Cycle time
is encountered, the screen will revert back to the Cycle time.
Move to the next station with a Cycle Time and press the n
button to return.
Once the desired station is displayed, the user can use
the j or k button to increase or decrease the Soak time.
The user can set the Soak time from 1 minute to 4 hours
in 1 minute increments.

Cycle and Soak Situations:
Station 1 requires 20 minutes of
watering, but after 5 minutes,
runoff occurs. However, after 10
