The EC controller uses a numbered seven-day calendar to schedule the days to water. The display will show the days of the week as numbers 1–7.

When programming the current time and day, you can select a number to represent the current day of the week. The number can be changed to represent the user's preference. Many people think of Sunday as day 1 while others think of Monday as day 1. The day number can be set to whatever works best for you.

Easy Retrieve Program Memory

The Pro-C controller is equipped with a delay between stations function. This feature allows the user to select a time delay between the end of one station run time and the start of another station's run time. The delay can be as short as a one second or up to 4 hours. The delay is a convenient feature when working with slow closing valves or slow well water recovery.

This feature allows the user to select a time delay between the end of one station run time and the start of another station's run time. The delay can be set for 1 second up to 4 hours. The delay is a convenient feature when working with slow closing valves or slow well water recovery.

Step 1. Check the controller programming

• Is there a watering Start Time programmed into the controller?
• Is the Watering Start Time programmed with correct time of day (i.e. AM or PM)?
• Is the Current Time set correctly (i.e. AM or PM)?
• Is today a Water Day? (i.e. Controller may be set for Even Days and today is the 21st)
• Is the controller set on Interval watering days?
• Are there Station Run Times programmed into the controller?

Step 2. Check the controller operation

If your controller shows irrigation running (Flashing Sprinkler Icon), and your sprinklers are not working, you may have a wiring problem at the valves or the irrigation water supply has been shut down.

If you have a master valve on your system (check for wire on the P/MV terminal), then your master valve may not be opening up. Check the wiring connections at the master valves for loose or corroded connections, or a bad solenoid.

Arc Adjustment

Adjustable heads are preset to approximately 180 degrees. The PGP-ADJ is adjustable from 40-360 degrees. The PGP Ultra is adjustable from 50-360 degrees. Sprinklers may be adjusted with water on or off. It is recommended that initial adjustments be made before installation. Note: Reference illustration above for arc adjustment socket location.

Hunter rotary sprinklers operate on a “gear drive” system. When in operation, water turns a small turbine in the base of the sprinkler, which drives a series of gears that cause the head to rotate. The Hunter gear drive mechanism is sealed from dirt and debris. Age, excessive pressure, or poor water quality may eventually allow particles of contamination to enter the gear drive.

If the sprinkler is no longer rotating and the water flow coming out of the sprinkler has decreased, you can first try cleaning out the filter by removing the pop-up assembly from the main body.
