Pro-C® No Zones Running

Pro-C - Flashing Sprinkler Icon, No Zones Running

If the controller display shows a station running, flashing sprinkler icon, or arrow pointing towards running, it sounds like the controller is doing its part. Maybe the water has been shut off to the zone valves. Go to the zone valve and turn the solenoid (where the wires are connected) 1/2 turn counter clockwise. If the valves have water, the sprinklers will come on even without the controller. See illustration below for activating the valve solenoid manually:

If the sprinklers turn on manually by twisting the solenoid, then the next step is to check for the proper voltage.

To confirm the proper voltage is getting to the valves using a voltmeter, follow the steps below:

If you need a new solenoid for the valve, Hunter makes our products and replacement parts available through our network of authorized distributors.

Step 1

Turn dial to MANUAL-ONE STATION position. Station run time will flash in the display. Use the arrow button to move to the desired station. You may use the plus (+) or minus (-)button to select the amount of time for a station to water. Turn the dial clockwise to the RUN position to run the station.
Step 2

Use a volt meter to confirm there is 25-28 volts VAC at the screw terminals marked "C" and the corresponding station screw terminal ("C" and "2" for example).
Step 3

Next, go to the valve in question and check the same two wires connected to the valve for the same voltage.
Step 4

If there is no voltage or low voltage at the valve, you may have a damaged wire or bad connection from the controller.
Step 5

If you have necessary voltage (25-28 VAC) at the valve then the solenoid may need to be replaced.

Any idea where zone valves are typically located?

2006 Model Pro-c 400 with two PCM 300 modules added. I test 24Vdc on the main module and all four zones work/test ok. I don’t detect any voltage on both of the pcm 300s. I’ve reseated them and reset the system several times. If I move a wire from zone five to zone four. That zone works so believe the wiring and solenoid to be Okay.
Since both PCM 300s are not showing any Vdc at any of the terminals. How do I know it’s the module, controller or both.

What’s the PM/V mean? My Pro-C has a loose black wire and PM/V has nothing connected to it. My display says “1 Err” . And will say “1 running” sometimes.

What if all 12 zones read 24 volts simultaneous, not just the one that should be running?
