Problem

The controller repeats itself or continuously waters, even when it should not be on (cycling repeatedly).

Cause

Too many start times (user error).

Solution

Only one start time per active program is required. The Start Time numbers do not represent station numbers.

Problem

There is no display.

Cause

Check AC power wiring.

Solution

Correct any errors. Make sure slide bar is in "Power On" position. Install 9v battery inside panel, if still no display replace Pro-C panel.

Problem

The display reads "SP ERR".

Cause

Electrical noise is entering the system.

Solution

Check the SmartPort® wiring harness. Verify that the red wire is attached to the AC1 terminal, the white wire to the AC2 terminal and the blue wire to the REM terminal. If the wires were extended then they will need to be replaced with shielded cable. Contact your local distributor for information on shielded cable.

Problem

The display reads “P ERR”.

Cause

  • Faulty pump relay or master valve wiring.
  • Incompatible or defective relay of solenoid.
  • Under sized wire to the pump or master valve.

Solution

  • Check the master valve or pump start wire for continuity. Replace or repair the shorted wire. Check that all wire connections are good and watertight.
  • Check electrical specifications for pump relay - Do not exceed controller's electrical rating. Replace defective pump relay or solenoid.
  • Replace wire with larger gauge wire.

Problem

The display reads a station number and ERR, such as “2 ERR”.

Cause

Short in valve wiring circuit, or faulty solenoid on the station number indicated.

Solution

Check wire circuit or solenoid for the valve number indicated. repair short or replace solenoid. Press any button to clear the "ERR" from the display.

Problem

The display reads “NO AC”.

Cause

There is no AC power present (the controller is not receiving power).

Solution

Check to see if the transformer is properly installed.

Problem

The display reads “SENSOR OFF”.

Cause

The rain sensor is interrupting irrigation or the sensor jumper is not installed.

Solution

Slide the Rain Sensor switch on front panel to the BYPASS position to bypass rain sensor circuit, or install the sensor jumper.

Problem

Rain sensor will not shut off system.

Cause

  • Incompatible rain sensor or the jumper was not removed when sensor was installed.
  • Manual Single Station Mode Used.

Solution

  • Make sure sensor is micro-switch type such as Mini-Clik®. Check that the jumper has been removed from the SEN terminals. Confirm proper operation (see “Testing the Weather Sensor”).
  • Manual Single Station Mode will override the sensor. Use Manual All Station Mode to test sensor.

Problem

The controller does not have a start time for each station.

Cause

Programming error, dial in incorrect position.

Solution

Be sure the dial is in correct position. Total number of stations can be easily checked by placing dial in the RUN TIMES position and pressing the back arrow.

Problem

Valve will not turn on.

Cause

  • Short in wiring connections.
  • Bad solenoid.

Solution

  • Check field wiring.
  • Replace solenoid.

Problem

Frozen display, or showing incorrect information

Cause

  • Power surge

Solution

  • Reset the controller

Problem

Automatic irrigation does not start at the start time and controller is not in the System Off mode

Cause

  • AM/PM of time of day not set correctly
  • AM/PM of start time not set correctly
  • Start Time is disabled (set for Off)

Solution

  • Correct AM/PM of time of day
  • Correct AM/PM of start time
  • See Setting Program Start Times

Problem

The display shows dashes when the dial is in the Solar Sync Settings position

Cause

  • The Solar Sync sensor is not connected to the controller
  • The Solar Sync sensor wires may have a break in them or a bad connection

Solution

  • Connect the Solar Sync to the "SEN" positions on the wiring terminal - The display will then show the Region and Water Adjustment setting
  • Check Solar Sync wiring

Problem

Run times for a particular station are too short/too long when using a Solar Sync sensor

Cause

  • Program Run Time too long/short

Solution

    Solar Sync provides a global seasonal adjustment to the controller - If a particular station has run times too long or too short, make the appropriate adjustment to the program in the controller - Make sure to change seasonal adjust back to 100% before making changes to program run times - Do this by turning the dial to the Seasonal Adjust position and increasing/decreasing the value to 100%

Problem

Seasonal Adjust seems low

Cause

  • Region too high
  • Water Adjustment too low
  • Location of Sensor does not allow for full sun

Solution

    Increase the value on the Water Adjustment scale (the default setting is 5) - If you max out on the Water Adjustment scale at 10 and still require more seasonal adjustment, move down one Region (from 4 to 3, for example) and start at Water Adjustment setting 5 - Solar Sync will immediately update the Seasonal Adjust on the controller - If it is still too high, repeat the adjustment until the desired seasonal adjust is showing on the controller

Problem

Seasonal Adjust seems high

Cause

  • Region too low
  • Water Adjustment setting too high

Solution

    Decrease the value of the Water Adjustment setting. If you minimize the Water Adjustment scale at 1 and still require reduced seasonal adjustment, move up one Region (from 2 to 3, for example) and start at Water Adjustment setting 5 - Solar Sync will immediately update the Seasonal Adjust on the Controller - If it is still too high, repeat the adjustment until the desired seasonal adjust is showing on the controller

Problem

Solar Sync still sending Seasonal Adjust when Controller Bypass switch is in the "Bypass" position

Cause

    Solar Sync’s automated Seasonal Adjustment cannot be de-activated by the Bypass switch. The Bypass switch only controls the Rain/Freeze shutoff function of the Solar Sync

Problem

After removing the Solar Sync sensor from the controller, the seasonal adjust value cannot be changed manually

Cause

  • The Solar Sync sensor needs to be uninstalled if permanently removing it from the controller

Solution

  • After removing the Solar Sync sensor from the controller, turn the knob to SOLAR SYNC. The screen should show dashed lines - The sensor is now uninstalled

Problem

Display shows "no SS"

Solution

  • Uninstall Solar Sync sensor if intent is to permanently remove sensor from controller
  • Check Solar Sync sensor wiring connection to controller
